6.8 Transmit modulation

25.1013GPPRelease 17TSUser Equipment (UE) radio transmission and reception (FDD)

Transmit modulation defines the modulation quality for expected in-channel RF transmissions from the UE. The requirements apply to all transmissions including the PRACH pre-amble and message parts and all other expected transmissions. In cases where the mean power of the RF signal is allowed to change versus time e.g. PRACH, DPCH in compressed mode, change of TFC, inner loop power control and for HSDPA transmissions with non-constant HS-DPCCH code power, the EVM, Peak Code Domain Error and E-DCH Code Domain Error requirements do not apply during the 25 us period before and after the nominal time when the mean power is expected to change.

6.8.1 Transmit pulse shape filter

The transmit pulse shaping filter is a root-raised cosine (RRC) with roll-off =0.22 in the frequency domain. The impulse response of the chip impulse filter RC0(t) is:

Where the roll-off factor =0.22 and the chip duration is

6.8.1A Additional requirement for UL OLTD

6.8.1B Additional requirement for UL CLTD

For UE with two active transmit antenna connectors in UL CLTD activation state 1, the transmit pulse shape filter requirements specified in sub-clause 6.8.1 apply at each transmit antenna connector.

For UE configured in UL CLTD activation state 2 or activation state 3, the transmit pulse shape filter requirements specified in sub-clause 6.8.1 apply at the active transmit antenna connector.

6.8.1C Additional requirement for UL MIMO

For UE with two active transmit antenna connectors in UL MIMO operation, the transmit pulse shape filter requirements specified in sub-clause 6.8.1 apply at each transmit antenna connector.

6.8.1D Additional requirement for DB-DC-HSUPA

For UE supporting DB-DC-HSUPA operation, the transmit pulse shape filter requirements specified in sub-clause 6.8.1 apply per carrier.

6.8.2 Error Vector Magnitude

The Error Vector Magnitude is a measure of the difference between the reference waveform and the measured waveform. This difference is called the error vector. Both waveforms pass through a matched Root Raised Cosine filter with bandwidth 3,84 MHz and roll-off =0,22. Both waveforms are then further modified by selecting the frequency, absolute phase, absolute amplitude and chip clock timing so as to minimise the error vector. The EVM result is defined as the square root of the ratio of the mean error vector power to the mean reference power expressed as a %. The measurement interval is one timeslot except when the mean power between slots is expected to change whereupon the measurement interval is reduced by 25 μs at each end of the slot. For the PRACH preamble the measurement interval is 4096 chips less 25 μs at each end of the burst (3904 chips).

When the UE uses 16QAM modulation on any of the uplink code channels in a carrier, the error minimization step also includes selecting an IQ origin offset besides selecting the frequency, absolute phase, absolute amplitude and chip clock timing to minimise the error vector. The IQ origin offset shall be removed from the evaluated signal before calculating the EVM; however, the removed relative IQ origin offset power (relative carrier leakage power) also has to satisfy the applicable requirement.

For signals containing more than one spreading code in a carrier where the slot alignment of the codes is not the same and the code power is varying, the period over which the nominal mean power in that carrier remains constant can be less than one timeslot. For such time-varying signals it is not possible to define EVM across one timeslot since this interval contains an expected change in mean power, and the exact timing and trajectory of the power change is not defined. For these signals, the EVM minimum requirements apply only for intervals of at least one half timeslot (less any 25μs transient periods) during which the nominal code power of each individual code is constant.

NOTE: The reason for setting a lower limit for the EVM measurement interval is that for any given impaired signal, the EVM would be expected to improve for measurement intervals less than one timeslot while the frequency error would be expected to degrade.

6.8.2.1 Minimum requirement

When 16QAM modulation is not used on any of the uplink code channels, the Error Vector Magnitude shall not exceed 17.5 % for the parameters specified in Table 6.15.

6.8.2.1E Additional requirement for DB-DC-HSUPA

For UE supporting DB-DC-HSUPA operation, the EVM requirements specified in sub-clause 6.8.2.1 apply at each carrier.

6.8.3 Peak code domain error

The Peak Code Domain Error is computed by projecting power of the error vector (as defined in 6.8.2) onto the code domain at a specific spreading factor. The Code Domain Error for every code in the domain is defined as the ratio of the mean power of the projection onto that code, to the mean power of the composite reference waveform. This ratio is expressed in dB. The Peak Code Domain Error is defined as the maximum value for the Code Domain Error for all codes. The measurement interval is one timeslot except when the mean power between slots is expected to change whereupon the measurement interval is reduced by 25 μs at each end of the slot.

The requirement for peak code domain error is only applicable for multi-code DPDCH transmission and therefore does not apply for the PRACH preamble and message parts.

6.8.3.1 Minimum requirement

The peak code domain error shall not exceed -15 dB at spreading factor 4 for the parameters specified in Table 6.15. The requirements are defined using the UL reference measurement channel specified in subclause A.2.5.

For UE with two active transmit antenna connectors in UL CLTD activation state 1, the peak code domain error shall not exceed -15 dB at spreading factor 4 for the parameters specified in Table 6.15. The requirements are defined using the UL reference measurement channel specified in subclause A.2.5A.

For UE configured in UL CLTD activation state 2 or activation state 3, the Peak code domain error requirements specified in sub-clause 6.8.3.1 apply at the active transmit antenna connector.

6.8.3.1C Additional requirement for DB-DC-HSUPA operating simultaneously with CS

For UE supporting DB-DC-HSUPA operating simultaneously with CS, the peak code domain error requirements specified in sub-clause 6.8.3.1 apply for the primary carrier.

6.8.3a Relative code domain error

6.8.3a.1 Relative Code Domain Error

The Relative Code Domain Error is computed by projecting the error vector (as defined in 6.8.2) onto the code domain. Only the code channels with non-zero betas in the composite reference waveform are considered for this requirement. The Relative Code Domain Error for every non-zero beta code in the domain is defined as the ratio of the mean power of the projection onto that non-zero beta code, to the mean power of the non-zero beta code in the composite reference waveform. This ratio is expressed in dB. The measurement interval is one timeslot except when the mean power between slots is expected to change whereupon the measurement interval is reduced by 25 μs at each end of the slot.

In the mode of DC-HSUPA, the requirement and corresponding measurements apply to each individual carrier when the total power in each of the assigned carriers is equal to each other.

The Relative Code Domain Error is affected by both the spreading factor and beta value of the various code channels in the domain. The Effective Code Domain Power (ECDP) is defined to capture both considerations into one parameter. It uses the Nominal CDP ratio (as defined in 6.2.3), and is defined as follows for each used code, k, in the domain:

ECDPk = (Nominal CDP ratio)k + 10*log10(SFk/256)

When 16QAM is not used on any of the UL code channels in a carrier, the requirements for Relative Code Domain Error are not applicable when either or both the following channel combinations occur:

– when the ECDP of any code channel is < -30dB

– when the nominal code domain power of any code channel is < -20 dB

When 16QAM is used on any of the UL code channels in a carrier, the requirements for Relative Code Domain Error are not applicable when either or both the following channel combinations occur:

– when the ECDP of any code channel is < -30dB

– when the nominal code domain power of any code channel is < -30 dB

The requirement for Relative Code Domain Error also does not apply for the PRACH preamble and message parts.

6.8.3a.1.1 Minimum requirement

6.8.5 Phase discontinuity for HS-DPCCH

Phase discontinuity for HS-DPCCH is the change in phase due to the transmission of the HS-DPCCH. In the case where the HS-DPCCH timeslot is offset from the DPCCH timeslot, the period of evaluation of the phase discontinuity shall be the DPCCH timeslot that contains the HS-DPCCH slot boundary. The phase discontinuity for HS-DPCCH result is defined as the difference between the absolute phase used to calculate the EVM for that part of the DPCCH timeslot prior to the HS-DPCCH slot boundary, and the absolute phase used to calculate the EVM for remaining part of the DPCCH timeslot following the HS-DPCCH slot boundary. In all cases the subslot EVM is measured excluding the transient periods of 25 μs.
