Throughout this clause, unless otherwise stated, requirements are given in terms of power levels at the antenna connector of the equipment. For equipment with integral antenna only, a reference antenna with 0 dBi gain shall be assumed.

For GMSK modulation, the term output power refers to the measure of the power when averaged over the useful part of the burst (see annex B).

For QPSK, AQPSK, 8-PSK, 16-QAM and 32-QAM modulation, the term output power refers to a measure that, with sufficient accuracy, is equivalent to the long term average of the power when taken over the useful part of the burst as specified in 3GPP TS 45.002 with any fixed TSC and with random encrypted bits.

The term peak hold refers to a measurement where the maximum is taken over a sufficient time that the level would not significantly increase if the holding time were longer.

NOTE: From a system perspective the over the air antenna performance is relevant. To determine the MS over the air performance the Total Radiated Power has been defined. Its definition can be found in 3GPP TS 25.144, and a test method is specified in 3GPP TS 34.114.

4.1 Output power

4.1.1 Mobile Station

The MS maximum output power and lowest power control level shall be, according to its class, as defined in the following tables.

i) MS maximum output power

NOTE 1: Power class E4 applies only to GSM 850 and E-GSM 900.

The maximum power for power class E1-E3 is corrected for the different modulations according to the table below

Table 4.1-3 Correction factor of maximum power for different modulations in table 4.1-2

Modulation	Correction factor (dB)
QPSK	0
8-PSK	0
16-QAM	-2
32-QAM	-2
NOTE: In the case and only in the case of EGPRS2-B with the spectrally wide pulse shaping filter and the tight spectrum requirement at 400 kHz offset from the carrier (see section 4.2.1), the actual maximum output power may be up to 2 dB lower than the lower limit of the maximum output power’s tolerance range defined by the power class table above and the correction factors of this table. In this case and only in this case, the MS need not use the highest power control level or the two highest power control levels for the respective modulation.

Maximum output power for GMSK in any one band shall always be equal to or higher than maximum output power for all other modulations for the same equipment in the same band.

A multi band MS has a combination of the power class in each band of operation from the table above. Any combination may be used.

For EC-GSM-IoT capable mobile stations only GMSK modulation is mandatory. 8-PSK modulation is optional.
For EC-GSM-IoT mobile stations at GMSK modulation only power classes 4 and 6 apply for GSM 850 and E-GSM 900, and power classes 1 and 6 apply for DCS 1800 and PCS 1900. Corresponding power classes for 8-PSK modulation are E2 and E4 for all bands.

The PCS 1 900, including its actual antenna gain, shall not exceed a maximum of 2 Watts (+33 dBm) EIRP per the applicable FCC rules for wideband PCS services [FCC Part 24, Subpart E, Section 24.232]. Power Class 3 is restricted to transportable or vehicular mounted units.

For GSM 850 MS, including its actual antenna gain, shall not exceed a maximum of 7 Watts (+38,5 dBm) ERP per the applicable FCC rules for public mobile services. [FCC Part 22, Subpart H, Section 22.913]

For GSM 700 MS, including its actual antenna gain, shall not exceed a maximum of 3 Watts (+35 dBm) ERP for handheld devices and maximum of 30 Watts (+45 dBm) ERP for other mobile devices per the applicable FCC rules. [FCC Part 27, Subpart C, Section 27.50].

ii) The different power control levels needed for adaptive power control and open-loop (EC-)RACH power control (see 3GPP TS 45.008) shall have the nominal output power as defined in the tables below, starting from the power control level for the lowest nominal output power up to the power control level for the maximum nominal output power corresponding to the class of the particular MS as defined in the tables above. Whenever a power control level commands the MS to use a nominal output power equal to or greater than the maximum nominal output power for the power class of the MS, the nominal output power transmitted shall be the maximum nominal output power for the MS class, and the tolerance specified for that class (see tables 4.1-1, 4.1-2 and 4.1-3 above) shall apply.

NOTE 1: This requirement applies only to MS that do not support EC-GSM-IoT. NOTE 2: The power control levels apply to EC-GSM-IoT MS.

NOTE 1: For DCS 1 800, the power control levels 29, 30 and 31 are not used when transmitting the parameter MS_TXPWR_MAX_CCH on BCCH, for cross phase compatibility reasons. If levels greater than 30 dBm are required from the MS during a random access attempt, then these shall be decoded from parameters broadcast on the BCCH as described in 3GPP TS 45.008.

Furthermore, the difference in output power actually transmitted by the MS between two power control levels where the difference in nominal output power indicates an increase of 2 dB (taking into account the restrictions due to power class), shall be +2 ± 1,5 dB. Similarly, if the difference in output power actually transmitted by the MS between two power control levels where the difference in nominal output power indicates an decrease of 2 dB (taking into account the restrictions due to power class), shall be ‑2 ± 1,5 dB.

NOTE 2: A 2 dB nominal difference in output power can exist for non‑adjacent power control levels e.g. power control levels 18 and 22 for GSM 400 and GSM 900; power control levels 31 and 0 for class 3 DCS 1 800 and power control levels 3 and 6 for class 4 GSM 400 and GSM 900.

A change from any power control level to any power control level may be required by the base transmitter. The maximum time to execute this change is specified in 3GPP TS 45.008.

NOTE 1: Tolerance for MS Power Classes 1 and 2 is 2 dB normal and 2,5 dB extreme at Power Control Levels 0 and 3 respectively. NOTE 2: This requirement applies only to MS that do not support EC-GSM-IoT. NOTE 3: The power control levels apply to EC-GSM-IoT MS.

The output power actually transmitted by the MS at each of the power control levels shall form a monotonic sequence, and the interval between power steps shall be 2 dB 1,5 dB except for the step between power control levels 30 and 31 where the interval is 1 dB 1 dB.

The MS transmitter may be commanded by the BTS to change from any power control level to any other power control level. The maximum time to execute this change is specified in 3GPP TS 45.008.

For CTS transmission, the nominal maximum output power of the MS shall be restricted to:

– 11 dBm (0,015 W) in GSM 900 i.e. power control level 16;

– 12 dBm (0,016 W) in DCS 1 800 i.e. power control level 9.

iii) In order to manage mobile terminal heat dissipation resulting from transmission on multiple uplink timeslots, a mobile station that is not in EC operation may reduce its maximum output power by up to the values in table 4.1-5. A mobile station in EC operation shall be capable of transmitting at the declared nominal output power for the duration of uplink data transfer, for any number of timeslots used.

Table 4.1-5 MS power reduction when transmitting on multiple uplink timeslots

Number of timeslots in uplink assignment	Permissible nominal reduction of maximum output power, (dB)
Number of timeslots in uplink assignment	Permissible nominal reduction of maximum output power, (dB)
1	0
2	3,0
3	4,8
4	6,0
5	7,0
6	7,8
7	8,5
8	9,0

The actual supported maximum output power shall be in the range indicated by the parameters XXX_MULTISLOT_POWER_PROFILE (See 3GPP TS 24.008) for n assigned uplink timeslots:

a  MS maximum output power  min(MAX_PWR, a + b)

Where:

a = min (MAX_PWR, MAX_PWR + XXX_MULTISLOT_POWER_PROFILE – 10log(n));

MAX_PWR equals to the MS maximum output power according to the relevant power class;

XXX_MULTISLOT_POWER_PROFILE refers either to GMSK_MULTISLOT_POWER PROFILE or 8‑PSK_MULTISLOT_POWER_PROFILE depending on the modulation type concerned, and

XXX_MULTISLOT_POWER_PROFILE 0 = 0 dB;

XXX_MULTISLOT_POWER_PROFILE 1 = 2 dB;

XXX_MULTISLOT_POWER_PROFILE 2 = 4 dB;

XXX_MULTISLOT_POWER_PROFILE 3 = 6 dB.

For DCS 1800 and PCS 1900 frequency bands b = 3 dB, for all other bands b = 2 dB.

For QPSK, 16-QAM and 32-QAM modulations 8-PSK_MULTISLOT_POWER_PROFILE shall apply, corrected for the difference in MAX_PWR for each modulation.

The supported maximum output power for each number of uplink timeslots shall form a monotonic sequence. The maximum reduction of maximum output power from an assignment of n uplink timeslots to an assignment of n+1 uplink timeslots shall be equal to the difference of maximum permissible nominal reduction of maximum output power for the corresponding number of timeslots, as defined in the table 4.1-5 above.

As an exception, in case of a multislot uplink assignment, the first power control step down from the maximum output power is allowed to be in the range 0…2 dB.

In case the MS transmits on more uplink slots than assigned (e.g. due to a polling response, see 3GPP TS 44.060), the MS may reduce uplink power as above for a multislot uplink configuration but as a function of the number of active uplink slots on a TDMA frame basis.

On a multislot uplink configuration the MS may restrict the interslot output power control range to a 10 dB window, on a TDMA frame basis. On those timeslots where the ordered power level is more than 10 dB lower than the applied power level of the highest power timeslot, the MS shall transmit at a lowest possible power level within 10 dB range from the highest applied power level, if not transmitting at the actual ordered power level.

4.1.2 Base station

a) Requirements for base stations except multicarrier BTS

For a normal BTS, the maximum output power measured at the input of the BSS Tx combiner, shall be, according to its class, as defined in the following table.

Table 4.1-6 Normal BTS power classes

GSM 400 & GSM 900 & ER-GSM 900 & GSM 850 & MXM 850 and GSM 700		DCS 1 800 & PCS 1 900 & MXM 1900

8	2,5 ‑ (< 5) W

For a micro‑BTS or a pico-BTS, the maximum output power per carrier measured at the antenna connector after all stages of combining shall be, according to its class, defined in the following table.

Table 4.1-7 Micro BTS and Pico BTS power classes

GSM 900 & ER-GSM 900 & GSM 850 & MXM 850 and GSM 700 micro and pico‑BTS		DCS 1 800 & PCS 1 900 & MXM 1900 micro and pico‑BTS

Pico		Pico
P1	(> 13) ‑ 20 dBm	P1	(> 16) ‑ 23 dBm

For BTS supporting QPSK, AQPSK, 8-PSK, 16-QAM and/or 32-QAM the manufacturer shall declare the maximum output power capability for GMSK and for each additionally supported combination of modulation and symbol rate.

The TRX power class is defined by the highest single carrier output power capability for any modulation.

b) Requirements for multicarrier BTS

For BTS belonging to a multicarrier BTS class, the manufacturer shall declare the maximum output power per carrier in case that all carriers are operated at the same nominal output power. The declaration shall be given for each modulation and for all supported number of carriers up to the maximum number on each antenna port. Additionally, the maximum total power supported shall be declared.

The maximum total output power measured at the antenna connector after all stages of combining shall be as declared by the manufacturer but within the limits of the multicarrier BTS class, specified in table 4.1-8.

Table 4.1-8 Multicarrier BTS classes

All bands
Multicarrier BTS class	Total output power limit per antenna port
Wide Area	(NOTE 2)
Medium Range	38 dBm
Local Area	24 dBm
NOTE 1: Medium Range and Local Area classes are not applicable for MXM 850 and MXM 1900 NOTE 2: There is no upper power limit for the Wide Area multicarrier BTS

c) Requirements for all types of base stations

The tolerance of the actual maximum output power of the BTS for each supported modulation shall be ±2 dB under normal conditions and ±2,5 dB under extreme conditions. Settings shall be provided to allow the output power to be reduced from the maximum level for the modulation with the highest output power capability in at least six steps of nominally 2 dB with an accuracy of ±1 dB for each modulation to allow a fine adjustment of the coverage by the network operator. In addition, the actual absolute output power for each supported modulation at each static RF power step (N), with the exception below for the highest RF power level for 8-PSK, AQPSK, QPSK, 16-QAM and 32-QAM shall be 2*N dB below the absolute output power at static RF power step 0 for the modulation with the highest output power capability with a tolerance of ±3 dB under normal conditions and ±4 dB under extreme conditions. The static RF power step 0 shall be the actual output power according to the TRX power class.

As an option the BSS can utilize downlink RF power control. In addition to the static RF power steps described above, the BSS may then for each supported modulation utilize up to 15 steps of power control levels with a step size of 2 dB ± 1,5 dB, in addition the actual absolute output power for each supported modulation at each power control level (N), with the exception below for the highest power level for QPSK, AQPSK, 8-PSK, 16-QAM and 32-QAM, shall be 2*N dB below the absolute output power at power control level 0 for the modulation with the highest output power capability with a tolerance of ±3 dB under normal conditions and ±4 dB under extreme conditions. The power control level 0 shall be the set output power according to the TRX power class and the six power settings defined above.

The output power for GMSK, QPSK, AQPSK, 8-PSK, 16-QAM and 32-QAM shall be nominally the same for any supported static RF power step and power control level. An exception is allowed for the maximum output power levels of respectively QPSK, AQPSK, 8-PSK, 16-QAM and 32-QAM which may be lower than the GMSK output power for the same power step or power control level. The nominal size of the first step down from the respective maximum power level of QPSK, AQPSK, 8-PSK, 16-QAM and 32-QAM may be in the range 0…2 dB. The output power for the GMSK, QPSK, AQPSK, 8-PSK, 16-QAM and 32-QAM at this power control level shall still be considered the same when required in 3GPP TS 45.008. The output power of QPSK, AQPSK, 8-PSK, 16-QAM and 32-QAM for the remaining power steps or power control levels shall be the same as the GMSK power for the corresponding power step or power control level within a tolerance of ±1 dB. The number of static RF power steps and the total number of power control steps may be different for GMSK and other modulations.

Network operators or manufacturers may also specify the BTS output power including any Tx combiner, according to their needs.

d) Requirements for base stations supporting EC-GSM-IoT

Additionally, when the base station transmits for an EC-PDTCH/EC-PACCH using four blind physical layer transmissions per TDMA frame (i.e. CC2, CC3 or CC4) with the same USF value in subsequent timeslots, then the equivalent combined power according to Annex T shall be at static RF power step 0 (without downlink RF power control) at least equal to:

– The declared maximum output power + 10 dB (under normal conditions)

– The declared maximum output power + 9.5 dB (under extreme conditions)

There are no separate performance requirements for EC-PDTCH/2TS or EC-PACCH/2TS.

4.1.2.1 Additional requirements for PCS 1 900 and MXM 1900 Base stations

The BTS transmitter maximum rated output power per carrier, measured at the input of the transmitter combiner, shall be, according to its TRX power class, as defined in the table 4.1-6 above. The base station output power may also be specified by the manufacturer or system operator at a different reference point (e.g. after transmitter combining).

The maximum radiated power from the BTS, including its antenna system, shall not exceed a maximum of 1 640 W EIRP, equivalent to 1 000 W ERP, per the applicable FCC rules for wideband PCS services [FCC part 24, subpart E, section 24.237].

4.1.2.2 Additional requirements for GSM 850 and MXM 850 Base stations

The maximum radiated power from the BTS, including its antenna system, shall not exceed a maximum of 500 W ERP, per the applicable FCC rules for public mobile services [FCC part 22, subpart H, section 22.913].

4.1.2.3 Additional requirements for GSM 700 Base stations

The maximum radiated power from the BTS, including its antenna system, shall not exceed a maximum 1000 W ERP for GSM 700 BTS per the applicable FCC rules [FCC Part 27, Subpart C, Section 27.50].

4.1.2.4 Additional requirements for ER-GSM 900 Base stations

The BTS transmitter maximum rated output power per carrier, measured at the input of the transmitter combiner, shall be, according to its TRX power class, as defined in the table 4.1-6 above.

The BTS transmitter maximum rated output power per carrier shall be subject to regulatory coordination to avoid uncoordinated system impacts (RF scenarios for ER-GSM introduction and the MCL to be used are given in 3GPP TR 45.050) based on the case of uncoordinated or coordinated deployment in the same geographical area with other systems in the E-GSM band as specified in this clause.

4.1.2.4.1 Uncoordinated deployment

In case of uncoordinated deployment with other systems in the E-GSM band, in order to prevent blocking, the BTS transmitter maximum rated output power per carrier, measured at the input of the transmitter combiner, in the frequency range 918-921 MHz, shall be at most:

i) -40.4 dBm + MCL + (f-918.2)*6 dB in case of coexistence with GSM BTS

ii) -58.7 dBm + MCL + (f-918.2)*11 dB in case of coexistence with UTRA and E-UTRA BS

where f = DL frequency in MHz, 918.2 ≤ f ≤ 921.0 and MCL=67dB.

4.1.2.4.2 Coordinated deployment

In case of coordinated deployment with other systems in the E-GSM band, MCL higher than 67 dB can be taken into account to allow higher output power from an ER-GSM BTS transmitting in 918-921 MHz.

4.2 Output RF spectrum

The specifications contained in this subclause apply to both BTS and MS, in frequency hopping as well as in non frequency hopping mode, except that beyond 1800 kHz offset from the carrier the BTS is not tested in frequency hopping mode.

Due to the bursty nature of the signal, the output RF spectrum results from two effects:

– the modulation process;

– the power ramping up and down (switching transients).

The two effects are specified separately; the measurement method used to analyse separately those two effects is specified in 3GPP TS 51.010 and 3GPP TS 51.021. It is based on the "ringing effect" during the transients, and is a measurement in the time domain, at each point in frequency.

The limits specified thereunder are based on a 5‑pole synchronously tuned measurement filter.

Unless otherwise stated, for the BTS, only one transmitter is active for the tests of this subclause.

4.2.1 Spectrum due to the modulation and wide band noise

4.2.1.1 General requirements for all types of Base stations and MS

The output RF modulation spectrum is specified in the tables in 4.2.1.3. A mask representation of this specification is shown in annex A. This specification applies for all RF channels supported by the equipment.

The specification applies to the entire of the relevant transmit band and up to 2 MHz either side.

The specification shall be met under the following measurement conditions:

– for BTS up to 1800 kHz from the carrier and for MS in all cases:

– zero frequency scan, filter bandwidth and video bandwidth of 30 kHz up to 1800 kHz from the carrier and 100 kHz at 1800 kHz and above from the carrier, with averaging done over 50 % to 90 % of the useful part of the transmitted bursts, excluding the midamble, and then averaged over at least 200 such burst measurements. Above 1800 kHz from the carrier only measurements centred on 200 kHz multiples are taken with averaging over 50 bursts.

– for BTS at 1800 kHz and above from the carrier:

– swept measurement with filter and video bandwidth of 100 kHz, minimum sweep time of 75 ms, averaging over 200 sweeps. All slots active, frequency hopping disabled.

– when tests are done in frequency hopping mode, the averaging shall include only bursts transmitted when the hopping carrier corresponds to the nominal carrier of the measurement. The specifications then apply to the measurement results for any of the hopping frequencies.

The figures in tables ax), bx) and cx) in 4.2.1.3, at the vertically listed power level (dBm) and at the horizontally listed frequency offset from the carrier (kHz), are then the maximum allowed level (dB) relative to a measurement in 30 kHz on the carrier.

NOTE: This approach of specification has been chosen for convenience and speed of testing. It does however require careful interpretation if there is a need to convert figures in the tables in subclause 4.2.1.3 into spectral density values, in that only part of the power of the carrier is used as the relative reference, and in addition different measurement bandwidths are applied at different offsets from the carrier. Appropriate conversion factors for this purpose are given in 3GPP TS 45.050.

For the BTS, the power level is the "actual absolute output power" defined in subclause 4.1.2. If the power level falls between two of the values in the tables in subclause 4.2.1.3, the requirement shall be determined by linear interpolation.

4.2.1.2 Additional requirements for multicarrier BTS

In case of multicarrier BTS, the requirements for spectrum due to modulation and wideband noise are based on the superposition of the single carrier spectrum requirements for all active carriers taking the different frequency offsets from each carrier into account. In addition to the measurements on a single carrier (4.2.1.1), the output spectrum shall be measured for frequency offsets between 400 kHz above the uppermost and below the lowermost carrier, respectively, and 10 MHz outside the transmit band with all carriers operating at full power at minimum carrier frequency spacing as well as with the carriers distributed across the declared maximum Base Station RF bandwidth as described in 3GPP TS 51.021 [18], specified for the BSS configuration under test. The following requirements apply:

– Depending on the active carrier number N, for frequency offsets higher than or equal to 1.8 MHz, the value of the spectrum due to modulation and wideband noise given for the measurement with single carrier may not increase by more than calculated from the expression 10∙log (N) dB, or fulfil the requirement according to the applicable multicarrier BTS class in subclause 4.7.2, whichever less stringent.

– For frequency offsets less than 1.8 MHz, the unwanted emission must not exceed a mask defined by the cumulation of the spectrum due to modulation and wideband noise from each carrier as well as the possibly occurring IM products.

– In addition, a number of allowable exceptions are defined as stated in vi) and vii).

NOTE: This approach has been chosen to limit the wideband noise in the multicarrier operation by aligning with the performance of normal BTSs transmitting several carriers. These BTSs use combiner stages to feed the antenna which leads to a degradation of the noise performance at the antenna in the way as specified above. Above 1.8 MHz frequency offset a generic expression as stated above is applied. For a frequency offset below 1.8 MHz there is no corresponding simple generic expression as the spectrum will be dependent on the output power, carrier spacing as well as the number of active carriers.

In case of non-contiguous frequency allocation and a multicarrier BTS supporting non-contiguous frequency allocations as defined in clause 3, spectrum due to modulation and wideband noise shall be measured for frequency offsets above the uppermost carrier and frequency offsets below the lowermost carrier as specified above depending on the total number of active carriers N. In addition it shall be measured inbetween the two frequency groups with the first frequency group located at carrier frequency A and lower frequencies and a second frequency group located at carrier frequency B and higher frequencies, where the bandwidth (B – A) specifies the bandwidth between the innermost carriers A and B. The following requirements apply for the range between the two frequency groups:

– Depending on the active carrier number N, for frequency offsets higher than or equal to 1.8 MHz both above the uppermost carrier A of the lower frequency group and below the lowermost carrier B of the upper frequency group the value of the spectrum due to modulation and wideband noise given for the measurement of the closest carrier of the innermost carriers A and B may not increase by more than calculated from the expression 10∙log (N) dB, or fulfil the requirement according to the applicable multicarrier BTS class in subclause 4.7.2, whichever less stringent.

– For frequency offsets less than 1.8 MHz above the uppermost carrier A of the lower frequency group or below the lowermost carrier B of the upper frequency group, the unwanted emission must not exceed a mask defined by the cumulation of the spectrum due to modulation and wideband noise from each of the N carriers and the IM products.

– In addition, a number of allowable exceptions are defined as stated in vii) and viii).

4.2.1.3 Tables for spectrum requirements due to modulation and wideband noise

Two types of requirements are specified, depending on symbol-rate and pulse-shaping filter used:

Case 1: Normal symbol rate using linearised GMSK pulse-shaping filter and higher symbol rate using spectrally narrow pulse shaping filter

Case 2: Higher symbol rate using spectrally wide pulse shaping filter

For definition of pulse-shaping filters, see 3GPP TS 45.004.

The spectrally narrow pulse shaping filter in Case 1 and the spectrally wide pulse shaping filter in Case 2 are in this specification referred to as narrow and wide pulse shaping filter respectively.

vii) At offsets larger than 600 kHz from the carrier, if a requirement in tables a2), b2) and c2), adjusted according to applicable multicarrier BTS requirements, is more stringent than lower limit in table 4.2-3a, the latter requirement shall be applied instead.

viii) The following applies in case of a non-contiguous frequency allocation as defined in clause 3: The same total number of exceptions M for N active carriers apply as given in vi) including the range of frequency offsets between 0.6 MHz above the uppermost carrier of the lower frequency group and 0.6 MHz below the lowermost carrier of the upper frequency group.

4.2.2 Spectrum due to switching transients

4.2.2.1 General requirements

Those effects are also measured in the time domain and the specifications assume the following measurement conditions: zero frequency scan, filter bandwidth 30 kHz, peak hold, and video bandwidth 100 kHz.

In case of the multicarrier BTS class, the measurement of the switching transients outside the BTS transmit band is covered by a measurement procedure stated in subclause 4.3 (Spurious emissions). For measurements of switching transients inside the transmit band, the measurement is performed with a single active carrier at maximum declared power..

The example of a waveform due to a burst as seen in a 30 kHz filter offset from the carrier is given thereunder (figure 1).

	400 kHz	600 kHz	1 200 kHz	1 800 kHz
39 dBm	‑21 dBm	‑26 dBm	‑32 dBm	‑36 dBm
 37 dBm	‑23 dBm	‑26 dBm	‑32 dBm	‑36 dBm

NOTE 1: The relaxation’s for power level 39 dBm is in line with the modulated spectra and thus causes negligible additional interference to an analogue system by a GSM signal.

NOTE 2: The near‑far dynamics with this specification has been estimated to be approximately 58 dB for MS operating at a power level of 8 W or 49 dB for MS operating at a power level of 1 W. The near‑far dynamics then gradually decreases by 2 dB per power level down to 32 dB for MS operating in cells with a maximum allowed output power of 20 mW or 29 dB for MS operating at 10 mW.

NOTE 3: The possible performance degradation due to switching transient leaking into the beginning or the end of a burst, was estimated and found to be acceptable with respect to the BER due to cochannel interference (C/I).

b) Base transceiver station:

The maximum level measured, after any filters and combiners, at the indicated offset from the carrier, is:

Table 4.2-4b Requirements for switching transients – BTS

	Maximum level measured
	400 kHz	600 kHz	1 200 kHz	1 800 kHz
GSM 400 & GSM 900 & ER-GSM 900 & GSM 850 & MXM 850 & GSM 700 (GMSK)	‑57 dBc	‑67 dBc	‑74 dBc	‑74 dBc
GSM 400 & GSM 900 & ER-GSM 900 & GSM 850 & MXM 850 & GSM 700 (QPSK, 8-PSK, 16-QAM, 32-QAM)	‑52 dBc	‑62 dBc	‑74 dBc	‑74 dBc
DCS 1 800 & PCS 1 900 & MXM 1900 (GMSK)	‑50 dBc	‑58 dBc	‑66 dBc	‑66 dBc
DCS 1 800 & PCS 1 900 & MXM 1900 (QPSK, 8-PSK, 16-QAM, 32-QAM)	‑50 dBc	‑58 dBc	‑66 dBc	‑66 dBc

Or ‑36 dBm, whichever is the higher.

dBc means relative to the output power at the BTS, measured at the same point and in a filter bandwidth of at least 300 kHz.

NOTE 4: Some of the above requirements are different from those specified in subclause 4.3.2.

4.3 Spurious emissions

The limits specified thereunder are based on a 5‑pole synchronously tuned measurement filter.

In addition to the requirements of this section, the PCS 1 900 & MXM 1900 BTS and PCS 1 900 MS shall also comply with the applicable limits for spurious emissions established by the FCC rules for wideband PCS services [FCC Title 47 CFR Part 24].

In addition to the requirements of this section, the GSM 850 & MXM 850 BTS and GSM 850 MS shall also comply with the applicable limits for spurious emissions established by the FCC rules for public mobile services [FCC Part 22, Subpart H].

In addition to the requirements of this section, the GSM 700 BTS and GSM 700 MS shall also comply with the applicable limits for spurious emissions established by the FCC [FCC Part 27, Subpart C, Section 27.53].

Note: This may introduce more stringent requirements than specified in this subclause for frequency bands dedicated for public safety services.

4.3.1 Principle of the specification

In this subclause, the spurious transmissions (whether modulated or unmodulated) and the switching transients are specified together by measuring the peak power in a given bandwidth at various frequencies. The bandwidth is increased as the frequency offset between the measurement frequency and, either the carrier, or the edge of the MS or BTS transmit band, increases. The effect for spurious signals of widening the measurement bandwidth is to reduce the allowed total spurious energy per MHz. The effect for switching transients is to effectively reduce the allowed level of the switching transients (the peak level of a switching transient increases by 6 dB for each doubling of the measurement bandwidth). The conditions are specified in the tables 4.3-1 and 4.3-2, a peak‑hold measurement being assumed.

In case of multicarrier BTS, instead of a peak-hold measurement an average measurement is assumed.

Furthermore, the measurement configuration as defined in 4.2.1 for multicarrier BTS shall be applied.

The measurement conditions for radiated and conducted spurious are specified separately in 3GPP TS 51.010 and 3GPP TS 51.02x series. The frequency bands where these are actually measured may differ from one type to the other (see 3GPP TS 51.010 and 3GPP TS 51.02x series).

a) Measurement bandwidth for inband measurements of spurious emissions

Table 4.3-1 Measurement bandwidth for inband measurements

Band	Frequency offset	Measurement bandwidth
	(offset from carrier)
relevant transmit	 1,8 MHz	30 kHz
band	 6 MHz	100 kHz

b) Measurement bandwidth for out-of-band measurements of spurious emissions

Band	Frequency offset	Measurement bandwidth
100 kHz to 50 MHz	‑	10 kHz
50 MHz to 500 MHz and outside the relevant transmit band	(offset from edge of the relevant transmit band)
	 2 MHz	30 kHz
	 5 MHz	100 kHz
500 MHz to 1000 MHz and	(offset from edge of the
outside the relevant transmit band	relevant transmit band)
	 2 MHz	30 kHz

	 5 MHz	100 kHz
	 10 MHz	300 kHz / 1 MHz ^(note)
	 20 MHz	1 MHz
	 30 MHz	3 MHz
NOTE: 1 MHz measurement bandwidth applies only to BTS belonging to a multicarrier BTS class.

The measurement settings assumed correspond, for the resolution bandwidth to the value of the measurement bandwidth in the table, and for the video bandwidth to approximately three times this value.

NOTE: For radiated spurious emissions for MS with antenna connectors, and for all spurious emissions for MS with integral antennas, the specifications currently only apply to the frequency band 30 MHz to 4 GHz. The specification and method of measurement outside this band are under consideration.

c) Relation to definitions and requirements in CEPT/ERC/REC 74-01 and ITU-R SM.329

In this subclause for all equipment the term Spurious emission out-of-band is used for all spurious transmissions outside the relevant transmit band (whether modulated or unmodulated), comprised of contributions from noise, intermodulation and non-harmonic emissions. For multicarrier BTS the definition of the requirements are aligned with the definitions in ITU-R SM.329 [34] and REC 74-01 in that

– Unwanted emissions in multicarrier operation are specified in subclause 4.2.1 (including the reference to intermodulation subclause 4.7.2) in present specification, both for inband and out-of band emissions from 0 MHz up to 2*BW frequency offset from edge of relevant transmit frequency band.

– Minimum required frequency allocation for each operator is assumed to be 5 MHz, i.e. BW is 5 MHz.

– Spurious emissions according to REC 74-01 definition are specified in subclause 4.3.2 from 2*BW = 10 MHz and higher frequency offsets. The 10 MHz spurious domain boundary applies also for larger transmitter bandwidths.

– In addition there is an upper limit for the unwanted emissions from 0 to 10 MHz frequency offset outside the relavant transmit band edge according to 4.3.2.1.

– The relevant transmit bands are defined in clause 2.

4.3.2 Base Transceiver Station

4.3.2.1 General requirements

i) The power measured in the conditions specified in subclause 4.3.1a shall be no more than ‑36 dBm. In case of multicarrier BTS, the requirements in subclause 4.2.1 for single carrier operation apply for the case of declared maximum output power.

ii) The power measured in the conditions specified in subclause 4.3.1b shall be no more than:

Table 4.3-3 Requirements for spurious emissions – out of relevant transmit band

		All BTS except multicarrier BTS	Multicarrier BTS
Band	Frequency offset outside relevant transmit band	Maximum power limit	Maximum power limit
			Wide Area	Medium Range	Local Area
9 kHz to 1 GHz	 2 MHz	-36 dBm (250 nW)	-25 dBm	-33 dBm	-46 dBm
	 5 MHz	-36 dBm	-20-4,2* (Δf – 5) dBm (Note)	-28-2,6* (Δf – 5) dBm (Note)	-41 dBm
	 10 MHz	-36 dBm	-36 dBm	-36 dBm	-36 dBm
1 GHz to 12.75 GHz	 2 MHz	-30 dBm (1 µW)	-25 dBm	-33 dBm	-45 dBm
	 5 MHz	-30 dBm	-20-3* (Δf – 5) dBm (Note)	-28-1.4* (Δf – 5) dBm (Note)	-40 dBm
	 10 MHz	-30 dBm	-30 dBm	-30 dBm	-30 dBm
Note: Δf is the frequency offset outside relevant transmit band in MHz

In case of multicarrier BTS, for frequency offsets between 0 and 10 MHz, the most stringent requirements of the requirements in the table above and the requirements in subclause 4.2.1 for multicarrier BTS with more than one carrier active apply.

In addition, applicable protection of critical services, in frequency bands outside the relevant TX band needs to be considered and measures taken to assure uninterrupted operation, according to additional requirements as defined by the regional regulator.

NOTE 1: For radiated spurious emissions for BTS, the specifications currently only apply to the frequency band 30 MHz to 4 GHz. The specification and method of measurement outside this band are under consideration.

iii) In the BTS receive band, the power measured using the conditions specified in subclause 4.2.1, with a filter and video bandwidth of 100 kHz shall be no more than :

Table 4.3-4 Requirements for spurious emissions – BTS receive band

	GSM 900 & ER-GSM 900 & GSM 850 & MXM 850 & GSM 700 (dBm)	DCS 1800 & PCS 1900 & MXM 1900 (dBm)

ER-GSM 900 BTS	-89
Wide Area multicarrier BTS	-98	-98

Local Area multicarrier BTS	-84	-84

These values assume a 30 dB coupling loss between transmitter and receiver. If BTSs of different classes are co‑sited, the coupling loss must be increased by the difference between the corresponding values from the table above.

iv) In case of BTSs belonging to a multicarrier BTS class, the measurement of the spurious emissions outside the BTS transmit band shall be conducted for the case of maximum supported number of carriers at maximum nominal power for each carrier while performing burst on/off keying. For measurements inside the relevant transmit band the measurement conditions and requirement in 4.2.1 regarding operation with one carrier active apply.

4.3.2.2 Additional requirements for co-existence with GSM systems on other frequency bands

i) For co-existence in the same geographic area, the powers measured in the conditions specified in subclause 4.2.1, with a filter and video bandwidth of 100 kHz, shall be no more than specified in table below:

NOTE 2: These requirements should also be applied to GSM 850 & MXM 850 BTS and PCS 1900 & MXM 1900 BTS built to a HW specification for R99 or earlier.

NOTE 3: These requirements should also be applied to any additional combination of BTSs in different frequency bands operating in the same geographic area.

ii) Measures must be taken for mutual protection of receivers when BTS of different bands are co‑sited.

NOTE 4: Thus, for this case, then the power measured from the BTS transmitter in the conditions specified in subclause 4.2.1, with a filter and video bandwidth of 100 kHz should be no more than the values in the table 4.3-4 in subclause 4.3.2.1, assuming the coupling losses stated in the same subclause, to protect co-sited BTS receivers for

– GSM 400 in the bands 450.4 – 457.6 MHz and 478.8 – 486.0 MHz

– T-GSM 810 in the band 806– 821 MHz

4.4 Radio frequency tolerance

The radio frequency tolerance for the base transceiver station and the MS is defined in 3GPP TS 45.010.

4.5 Output level dynamic operation

NOTE: The term "any transmit band channel" is used here to mean:

– any RF channel of 200 kHz bandwidth centred on a multiple of 200 kHz which is within the relevant transmit band.

4.5.1 Base Transceiver Station

The BTS shall be capable of not transmitting a burst in a time slot not used by a logical channel or where DTX applies. The output power relative to time when sending a burst is shown in annex B. The reference level 0 dB corresponds to the output power level according to subclause 4. In the case where the bursts in two (or several) consecutive time slots are actually transmitted, at the same frequency, the template of annex B shall be respected during the useful part of each burst and at the beginning and the end of the series of consecutive bursts. The output power during the guard period between every two consecutive active timeslots shall not exceed the level allowed for the useful part of the first timeslot, or the level allowed for the useful part of the second timeslot plus 3 dB, whichever is the highest. The residual output power, if a timeslot is not activated, shall be maintained at, or below, a level of ‑30 dBc on the frequency channel in use. All emissions related to other frequency channels shall be in accordance with the wide band noise and spurious emissions requirements.

A measurement bandwidth of at least 300 kHz is assumed.

4.5.2 Mobile Station

The output power can be reduced by steps of 2 dB as listed in subclause 4.1.

The transmitted power level relative to time when sending a burst is shown in annex B. The reference level 0 dB corresponds to the output power level according to subclause 4. In the case of Multislot Configurations where the bursts in two or more consecutive time slots are actually transmitted at the same frequency, the template of annex B shall be respected during the useful part of each burst and at the beginning and the end of the series of consecutive bursts. The output power during the period between the useful parts of every two consecutive active timeslots shall not exceed the level allowed for the useful part of the first timeslot, or the level allowed for the useful part of the second timeslot plus 3 dB, whichever is the highest. As an exception, in the case of a normal burst being transmitted with a high timing advance immediately after an access burst, a minimum of 8.25 symbol guard period shall be allowed for the MS power ramping and the useful part requirements for the concerned bursts are allowed to be adjusted correspondingly. The timing of the transmitted burst is specified in 3GPP TS 45.010. Between the active bursts, the residual output power shall be maintained at, or below, the level of:

‑ ‑59 dBc or ‑54 dBm, whichever is the greater for GSM 400, GSM 900, ER-GSM 900, GSM 850 and GSM 700, except for the time slot preceding the active slot, for which the allowed level is ‑59 dBc or ‑36 dBm whichever is the greater;

‑ ‑48 dBc or ‑48 dBm, whichever is the greater for DCS 1 800 and PCS 1 900;

in any transmit band channel.

A measurement bandwidth of at least 300 kHz is assumed.

The transmitter, when in idle mode, will respect the conditions of subclause 4.3.3.

4.6 Modulation accuracy

4.6.1 GMSK modulation

When transmitting a burst, the phase accuracy of the signal, relative to the theoretical modulated waveforms as specified in 3GPP TS 45.004, is specified in the following way.

For any 148‑bits subsequence of the 511‑bits pseudo‑random sequence, defined in CCITT Recommendation O.153 fascicle IV.4, the phase error trajectory on the useful part of the burst (including tail bits), shall be measured by computing the difference between the phase of the transmitted waveform and the phase of the expected one. The RMS phase error (difference between the phase error trajectory and its linear regression on the active part of the time slot) shall not be greater than 5° with a maximum peak deviation during the useful part of the burst less than 20°.

NOTE: Using the encryption (ciphering mode) is an allowed means to generate the pseudo‑random sequence.

The burst timing of the modulated carrier in the active part of the time slot shall be chosen to ensure that all the modulating bits in the useful part of the burst (see 3GPP TS 45.004) influence the output phase in a time slot.

4.6.2 QPSK, AQPSK, 8-PSK, 16-QAM and 32-QAM modulations

The modulation accuracy is defined by the error vector between the vector representing the actual transmitted signal and the vector representing the error-free modulated signal. The magnitude of the error vector is called Error Vector Magnitude (EVM). For definition of the different measures of EVM, see annex G.

When transmitting a burst, the magnitude of the error vector of the signal, relative to the theoretical modulated waveforms as specified in 3GPP TS 45.004, is specified in the following way.

The magnitude of the error vector shall be computed by measuring the error vector between the vector representing the transmitted waveform and the vector representing the ideal one on the useful part of the burst (excluding tail symbols). When measuring the error vector a receive filter at baseband shall be used, defined as

– a raised-cosine filter with roll-off 0,25 and single side-band 6 dB bandwidth 90 kHz for normal symbol rate and for higher symbol-rate using narrow pulse-shaping filter.

– a raised-cosine filter with roll-off 0,25 and single side-band 6 dB bandwidth 108 kHz for higher symbol-rate using wide pulse-shaping filter.

The measurement filter is windowed by multiplying its impulse response by a raised cosine window given as:

where T is the normal symbol period.

The transmitted waveforms shall be Normal Bursts for QPSK, AQPSK, 8-PSK, 16-QAM and 32-QAM as defined in 3GPP TS 45.002, with encrypted bits generated using consecutive bits from the 32767 bit length pseudo random sequence defined in ITU-T Recommendation O.151 (1992).

4.6.2.2 Origin Offset Suppression

The origin offset shall be measured over at least 200 bursts. For each burst a value shall be calculated using the formula for the origin offset suppression shown in annex G, but before taking the logarithm the average over the number of bursts shall be computed.

The 95:th percentile is the point where 95% of the individual EVM values, measured at each symbol interval, is below that point. That is, only 5% of the symbols are allowed to have an EVM exceeding the 95:th-percentile point. The EVM values are acquired during the useful part of the burst, excluding tail bits, over 200 bursts.

– The measured 95:th-percentile value shall be < 15 % for MS under normal and extreme conditions.

4.6.3 Phase and amplitude coherency when using blind physical layer transmissions

4.6.3.1 General

Phase and amplitude coherency for blind physical layer transmissions is achieved by repeating a Tx burst in subsequent timeslots with the same amplitude and phase. As an exception, different USF values are allowed in different DL timeslots.

No coherency of blind physical layer transmissions between TDMA frames is required.

4.6.3.2 EC-GSM-IoT MS

Using the same pseudo‑random encrypted bits in all active timeslots, the error vector of the useful part of the burst (including tail bits), shall be measured by computing the difference between the phase and amplitude of any two bursts of the blind physical layer transmissions over consecutive timeslots within a given TDMA frame.

The normalized coherency error () is defined in Annex S.

The between any two bursts of the blind physical layer transmissions transmitted over consecutive timeslots in CC2, CC3, CC4 shall not exceed -23 dB at received signal levels from the maximum applicable level for NER, specified for static conditions at a bit error rate of 10^-3 in subclause 6.1.1.2, down to the reference sensitivity level of EC-SCH, see table 1aa. For CC5 EC-RACH using EDAB the between first 82 symbols of the first burst and first 82 symbols of the second burst shall not exceed -23dB at received signal levels from the maximum applicable level for NER, specified for static conditions at a bit error rate of 10^-3 in subclause 6.1.1.2, down to the reference sensitivity level of EC-SCH, see table 1aa.

The phase and amplitude coherency requirement applies to the 2 TS EC-RACH mapping for CC2 to CC4, CC5 using EDAB format, EC-PDTCH, EC-PDTCH/2TS, EC-PACCH and EC-PACCH/2TS, see 3GPP TS 45.002 for how the bursts of a block for a specific logical channel are mapped onto the physical channel(s). The requirement applies for any given Overlaid CDMA code assigned, see 3GPP TS 44.018.

4.6.3.3 BTS supporting EC-GSM-IoT

Phase and amplitude coherency for blind physical layer transmissions according to subclause 4.6.3.1 is required for EC-PDTCH and EC-PACCH (see subclause 4.1.2 d) as well as EC-PDTCH/2TS and EC-PACCH/2TS.

4.7 Intermodulation attenuation

The intermodulation attenuation is the ratio of the power level of the wanted signal to the power level of an intermodulation component. It is a measure of the capability of the transmitter to inhibit the generation of signals in its non‑linear elements caused by the presence of the carrier and an interfering signal reaching the transmitter via the antenna, or by non linear combining and amplification of multiple carriers.

4.7.1 Base transceiver station

An interfering CW signal shall be applied to the transmit antenna port, within the relevant BTS TX band at a frequency offset of  800 kHz, and with a power level 30 dB below the power level of the wanted signal.

The intermodulation products shall meet the requirements in subclause 4.7.2.

4.7.2 Intra BTS intermodulation attenuation

In a BTS intermodulation may be caused by combining several RF channels or amplification of multiple carriers to feed a single antenna, or when operating them in the close vicinity of each other.

i) The BTS shall be configured with each transmitter operating at the maximum allowed power, with a full complement of transceivers and with modulation applied.
The requirement specified for the multicarrier BTS shall apply for all supported configurations of the multicarrier BTS independently of the number of active carriers, assuming equal power distribution between all carriers, and independently of the modulation type.

ii) For the measurement in the transmit band the equipment shall be operated at equal and minimum carrier frequency spacing as well as with the carriers distributed across the declared maximum Base Station RF bandwidth as described in 3GPP TS 51.021 [18], specified for the BSS configuration under test.

iii) For the measurement in the receive band the equipment shall be operated with such a channel configuration that at least 3rd order intermodulation products fall into the receive band.
