6.3.2EA Minimum Output Power for UE category M1

36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

6.3.2EA.1 Test purpose

To verify the UE’s ability to transmit with a broadband output power below the value specified in the test requirement when the power is set to a minimum value.

6.3.2EA.2 Test applicability

This test case applies to all types of E-UTRA UE release 13 and forward of UE category M1.

6.3.2EA.3 Minimum conformance requirements

The minimum output power is defined as the mean power in one sub-frame (1ms). The minimum output power shall not exceed the values specified in Table 6.3.2EA.3-1.

Table 6.3.2EA.3-1: Minimum output power

	Channel bandwidth / minimum output power / measurement bandwidth
	1.4 MHz	3.0 MHz	5 MHz	10 MHz	15 MHz	20 MHz
Minimum output power	-40 dBm
Measurement bandwidth	1.08 MHz	2.7 MHz	4.5 MHz	9.0 MHz	13.5 MHz	18 MHz

The normative reference for this requirement is TS 36.101 [2] clause 6.3.2.1.

Minimum output power test verifies the UE’s ability to transmit with a broadband output power below the specified limit when the power is set to a minimum value. The broadband output power is defined as the power in the channel bandwidth, for all transmit bandwidth configurations (resource blocks).

An excess minimum output power potentially increases the Rise Over Thermal (RoT) and therefore reduces the cell coverage area for other UEs.

6.3.2EA.4 Test description

6.3.2EA.4.1 Initial condition

Initial conditions are a set of test configurations the UE needs to be tested in and the steps for the SS to take with the UE to reach the correct measurement state.

The initial test configurations consist of environmental conditions, test frequencies, and channel bandwidths based on E-UTRA operating bands specified in table 5.2E. All of these configurations shall be tested with applicable test parameters for each channel bandwidth, and are shown in table 6.3.2EA.4.1-1. The details of the uplink reference measurement channels (RMCs) are specified in Annex A.2. Configurations of PDSCH and MPDCCH before measurement are specified in Annex C.2.

Table 6.3.2EA.4.1-1: Test Configuration Table

Initial Conditions
Test Environment as specified in TS 36.508 [7] subclause 4.1		Normal, TL/VL, TL/VH, TH/VL, TH/VH
Test Frequencies as specified in TS 36.508 [7] subclause 4.3.1		Low range, Mid range, High range
Test Channel Bandwidths as specified in TS 36.508 [7] subclause 4.3.1		5MHz
Test Parameters for Channel Bandwidths
	Downlink Configuration		Uplink Configuration
Ch BW	N/A for min output power test		Mod’n	RB allocation
				FDD and HD-FDD	TDD	Narrowband index (Note 1)
5MHz			QPSK	6	6	0
Note 1: Denote where in the channel bandwidth the narrowband shall be placed. Narrowband and narrowband index are defined in TS 36.211, 5.2.4. Note 2: Test Channel Bandwidths are checked separately for each E-UTRA band, the applicable channel bandwidths are specified in Table 5.4.2.1-1.

1. Connect the SS to the UE antenna connectors as shown in TS 36.508 [7] Annex A, in Figure A.3 using only main UE Tx/Rx antenna.

2. The parameter settings for the cell are set up according to TS 36.508 [7] subclause 4.4.3.

3. Downlink signals are initially set up according to Annex C.0, C.1, and C.3.0, and uplink signals according to Annex H.1 and H.3.0.

4. The UL Reference Measurement channel is set according to Table 6.3.2EA.4.1-1

5. Propagation conditions are set according to Annex B.0.

6. Ensure the UE is in State 3A-RF-CE according to TS 36.508 [7] clause 5.2A.2AA. Message contents are defined in clause 6.3.2EA.4.3.

6.3.2EA.4.2 Test procedure

1. SS sends uplink scheduling information for each UL HARQ process via MPDCCH DCI format 6-0A for C_RNTI to schedule the UL RMC according to Table 6.3.2EA.4.1-1. Since the UE has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL RMC.

2. Send continuous uplink power control "down" commands in the uplink scheduling information to the UE to ensure that the UE transmits at its minimum output power.

3. Measure the mean power of the UE in the associated measurement bandwidth specified in Table 6.3.2EA.5-1 for the specific channel bandwidth under test. The period of measurement shall be the continuous duration of one sub-frame (1ms). For TDD slots with transient periods are not under test. For HD-FDD slots with transient periods and Half-duplex guard subframe are not under test.

6.3.2EA.4.3 Message contents

Message contents are according to TS 36.508 [7] subclause 4.6.

6.3.2EA.5 Test requirements

The minimum output power measured shall not exceed the values specified in Table 6.3.2EA.5-1.

Table 6.3.2EA.5-1: Minimum output power for UE category M1

	Channel bandwidth / minimum output power / measurement bandwidth
	1.4 MHz	3.0 MHz	5 MHz	10 MHz	15 MHz	20 MHz
Minimum output power	For carrier frequency f ≤ 3.0GHz: ≤ -39 dBm For carrier frequency 3.0GHz < f ≤ 4.2GHz: ≤ -38.7 dBm
Measurement bandwidth (Note 1)	1.08 MHz	2.7 MHz	4.5 MHz	9.0 MHz	13.5 MHz	18 MHz
Note 1: Different implementations such as FFT or spectrum analyzer approach are allowed. For spectrum analyzer approach the measurement bandwidth is defined as an equivalent noise bandwidth.
