38.521-23GPPNRPart 2: Range 2 StandaloneRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
6.3.4.1 General
The requirements on power control accuracy apply under normal conditions and are defined as a directional requirement. The requirements are verified in beam locked mode on beam peak direction.
6.3.4.2 Absolute power tolerance
Editor’s Note: The following aspects are either missing or not yet determined:
- Testing of extreme conditions for FR2 is FFS.
- UE transmitted power for PC 1, 2 and 4 are FFS
- The reduction of the impact of DL MU by choosing alpha < 1 is FFS.
6.3.4.2.1 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.
To verify the ability of the UE transmitter to set its initial output power to a specific value at the start of a contiguous transmission or non-contiguous transmission with a long transmission gap, i.e. transmission gap is larger than 20 ms.
6.3.4.2.2 Test applicability
This test case applies to all types of NR UE release 15 and forward.
6.3.4.2.3 Minimum conformance requirements
The absolute power tolerance is the ability of the UE transmitter to set its initial output power to a specific value for the first sub-frame (1ms) at the start of a contiguous transmission or non-contiguous transmission with a transmission gap larger than 20 ms. The tolerance includes the channel estimation error RSRP estimate.
The minimum requirements specified in Table 6.3.4.2.3-1 apply in the power range bounded by the minimum output power as specified in sub-clause 6.3.1 (Pmin) and the maximum output power as specified in sub-clause 6.2.1.1 as minimum peak EIRP (‘Pmax’). The intermediate power point ‘Pint‘ is defined in table 6.3.4.2.3-2.

6.3.4.3.4.2 Test procedure
The procedure is separated in various subtests to verify different aspects of relative power control. The power patterns of the subtests are described in Figure 6.3.4.3.4.2-1 through Figure 6.3.4.3.4.2-3. The power patterns and corresponding sub frame numberings are derived from Table A.2.3-1.

Figure 6.3.4.3.4.2-2: TDD ramping down test power patterns, SCS 60kHz
Figure 6.3.4.3.4.2-3: Alternating Test Power patterns, SCS 60kHz
1. Sub test: ramping up pattern
1.1 SS sends uplink scheduling information for each UL HARQ process via PDCCH DCI format 0_1 for C_RNTI to schedule the UL RMC according to Table 6.3.4.3.4.1-1. Since the UE has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL RMC.
1.2 Set the UE in the Tx beam peak direction found with a 3D EIRP scan as performed in Annex K.1.1. Allow at least BEAM_SELECT_WAIT_TIME (NOTE 1) for the UE Tx beam selection to complete.
1.3 Send the appropriate TPC commands in the uplink scheduling information to UE until the UE EIRP measured by the test system is within the Uplink power control window, defined as +MU to +(MU + Uplink power control window size) dB of the target power level Pmin, where:
– Pmin is the minimum output power according to subclause 6.3.1.3.
– MU is the test system uplink power measurement uncertainty and is specified in Table F.1.2-1 for the carrier frequency f and the channel bandwidth BW.
– Uplink power control window size = 1dB (UE power step size) + 5dB (UE power step tolerance) + (Test system relative power measurement uncertainty), where, the UE power step tolerance is specified in TS 38.101-2 [3], Table 6.3.4.3-1 and is 5dB for 1dB power step size, and the Test system relative power measurement uncertainty is specified in Table F.1.2-1.
Allow at least BEAM_SELECT_WAIT_TIME (NOTE 1) for the UE Tx beam selection to complete.
1.4 SS activates the UE Beamlock Function (UBF) by performing the procedure as specified in TS 38.508-1 [10] clause 4.9.2 using condition Tx only.
1.5 Schedule the UE’s PUSCH data transmission as described in Figure 6.3.4.3.4.2-1 (TDD) pattern A: Uplink RB allocation as defined in Table 6.3.4.3.5-1. On the PDCCH format 0_1 for the scheduling of the PUSCH the SS will transmit +1dB TPC commands over a sequence of 75 (NOTE 2) active uplink sub-frames to ensure that the UE reaches maximum power threshold. Note that the measurement need not be done continuously, provided that interruptions are whole numbers of frames, and TPC commands of 0dB are sent during the interruption.
1.6 Measure UE EIRP in the Tx beam peak direction in the channel bandwidth of the radio access mode according to the test configuration, to verify the UE relative power control meet test requirements in 6.3.4.3.5. EIRP test procedure is defined in Annex K.1.3. EIRP is calculated considering both polarizations, theta and phi. Measurement of the power is not required in sub-frame after the mean power has exceeded the maximum power threshold. For power transients between sub-frames, transient periods of 40us between sub-frames are excluded. For ON/OFF or OFF/ON transients, transient periods of 20 us at the beginning of the sub-frames are excluded.
1.7 Repeat the subtest different pattern B, C to move the RB allocation change at different points in the pattern as described in Table 6.3.4.3.5-1 to force different UE power steps at various points in the power range.
1.8 SS deactivates the UE Beamlock Function (UBF) by performing the procedure as specified in TS 38.508-1 [10] clause 4.9.3.
2. Sub test: ramping down pattern
2.1 SS sends uplink scheduling information for each UL HARQ process via PDCCH DCI format 0_1 for C_RNTI to schedule the UL RMC according to Table 6.3.4.3.4.1-1. Since the UE has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL RMC.
2.2 Set the UE in the Tx beam peak direction found with a 3D EIRP scan as performed in Annex K.1.1. Allow at least BEAM_SELECT_WAIT_TIME (NOTE 1) for the UE Tx beam selection to complete.
2.3 Send the appropriate TPC commands in the uplink scheduling information to UE until the UE EIRP measured by the test system is within the Uplink power control window, defined as +MU to +(MU + Uplink power control window size) dB of the target power level PUMAX, where:
– PUMAX is the maximum output power according to subclause 6.2.1.1.3.
– MU is the test system uplink power measurement uncertainty and is specified in Table F.1.2-1 for the carrier frequency f and the channel bandwidth BW.
– Uplink power control window size = 1dB (UE power step size) + 1dB (UE power step tolerance) + (Test system relative power measurement uncertainty), where, the UE power step tolerance is specified in TS 38.101-2 [3], Table 6.3.4.3-2 and is 1dB for 1dB power step size, and the Test system relative power measurement uncertainty is specified in Table F.1.2-1.
Allow at least BEAM_SELECT_WAIT_TIME (NOTE 1) for the UE Tx beam selection to complete.
2.4 SS activates the UE Beamlock Function (UBF) by performing the procedure as specified in TS 38.508-1 [10] clause 4.9.2 using condition Tx only.
2.5. Schedule the UE’s PUSCH data transmission as described in Figure 6.3.4.3.4.2-2 (TDD) pattern A: Uplink RB allocation as defined in Table 6.3.4.3.5-2. On the PDCCH format 0_1 for the scheduling of the PUSCH the SS will transmit -1dB TPC commands over a sequence of 75 (NOTE 2) active uplink sub-frames to ensure that the UE reaches minimum power threshold. Note that the measurement need not be done continuously, provided that interruptions are whole numbers of frames, and TPC commands of 0dB are sent during the interruption.
2.6. Measure UE EIRP in the Tx beam peak direction in the channel bandwidth of the radio access mode according to the test configuration, to verify the UE relative power control meet test requirements in 6.3.4.3.5. EIRP test procedure is defined in Annex K.1.3. EIRP is calculated considering both polarizations, theta and phi. Measurement of the power is not required in sub-frame after the mean power has exceeded the maximum power threshold. For power transients between sub-frame, transient periods of 40us between sub-frame are excluded. For ON/OFF or OFF/ON transients, transient periods of 20 us at the beginning of the sub-frame are excluded.
2.7. Repeat the subtest different pattern B, C to move the RB allocation change at different points in the pattern as described in Table 6.3.4.3.5-2 to force different UE power steps at various points in the power range.
2.8 SS deactivates the UE Beamlock Function (UBF) by performing the procedure as specified in TS 38.508-1 [10] clause 4.9.3.
3. Sub test: alternating pattern
3.1 SS sends uplink scheduling information for each UL HARQ process via PDCCH DCI format 0_1 for C_RNTI to schedule the UL RMC according to Table 6.3.4.3.4.1-1. Since the UE has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL RMC. The initial uplink RB allocation is defined as the smaller uplink RB allocation value specified in Table 6.3.4.3.4.1-1. The power level and RB allocation are reset for each sub-test.
3.2 Set the UE in the Tx beam peak direction found with a 3D EIRP scan as performed in Annex K.1.1. Allow at least BEAM_SELECT_WAIT_TIME (NOTE 1) for the UE Tx beam selection to complete.
3.3 Send the appropriate TPC commands in the uplink scheduling information to UE until the UE EIRP measured by the test system is within the Uplink power control window, defined as +MU to +(MU + Uplink power control window size) dB of the target power level 0 dBm, where:
– MU is the test system uplink power measurement uncertainty and is specified in Table F.1.2-1 for the carrier frequency f and the channel bandwidth BW.
– Uplink power control window size is same as defined in step 1.3.
Allow at least BEAM_SELECT_WAIT_TIME (NOTE 1) for the UE Tx beam selection to complete.
3.4 SS activates the UE Beamlock Function (UBF) by performing the procedure as specified in TS 38.508-1 [10] clause 4.9.2 using condition Tx only.
3.5. Schedule the UE’s PUSCH data transmission as described in Figure 6.3.5.2.4.2-3 for 5 frames with an uplink RB allocation alternating pattern as defined in Table 6.3.4.3.5-3 while transmitting 0dB TPC command for PUSCH via the PDCCH.
3.6. Measure UE EIRP in the Tx beam peak direction in the channel bandwidth of the radio access mode according to the test configuration, to verify the UE relative power control meet test requirements in 6.3.4.3.5. EIRP test procedure is defined in Annex K.1.3. EIRP is calculated considering both polarizations, theta and phi. Measurement of the power is not required in sub-frame after the mean power has exceeded the maximum power threshold. For power transients between sub-frames, transient periods of 40us between sub-frames are excluded. For ON/OFF or OFF/ON transients, transient periods of 20 us at the beginning of the sub-frame are excluded.
3.7 SS deactivates the UE Beamlock Function (UBF) by performing the procedure as specified in TS 38.508-1 [10] clause 4.9.3.
NOTE 1: The BEAM_SELECT_WAIT_TIME default value is defined in Annex K.1.1.
NOTE 2: These numbers of TPC commands are given as examples. The actual number of TPC commands transmitted in these steps shall be enough to ensure that the UE reaches the relevant maximum or minimum power threshold in each step, as shown in Figure 6.3.4.3.4.2-1 through 6.3.4.3.4.2-3.
6.3.4.3.4.3 Message contents
Message contents are according to TS 38.508-1 [10] subclause 4.6 with TRANSFORM_PRECODER_ENABLED condition in Table 4.6.3-118 PUSCH-Config.
6.3.4.3.5 Test requirement
Each UE power step measured in the test procedure 6.3.4.3.4.2 should satisfy the test requirements specified in Table 6.3.4.3.5-1 through 6.3.4.3.5-3.
For a test pattern that is either a monotonically increasing or monotonically decreasing power sweep over the range specified for Tables 6.3.4.3.3-1and 6.3.4.3.3-2, 3 exceptions are allowed for each of the test patterns. For these exceptions, the power tolerance limit is a maximum of ± (11.0 + TT) dB. If there is an exception in the power step caused by the RB change for all test patterns (A, B, C) then fail the UE.

1. Connection between SS and UE is shown in TS 38.508-1 [10] Annex A, Figure A.3.3.1.1 for TE diagram and Figure A.3.4.1.1 for UE diagram.
2. The parameter settings for the cell are set up according to TS 38.508-1 [10] clause 4.4.3.
3. Downlink signals are initially set up according to Annex C, and uplink signals according to Annex G.
4. For PUCCH subtest, the UL and DL Reference Measurement Channels are set according to Table 6.3.4.4.4.1-1. For PUSCH subtest, the UL Reference Measurement Channel is set according to Table 6.3.4.4.4.1-2.
5. Propagation conditions are set according to Annex B.0.
6. Ensure the UE is in State RRC_CONNECTED with generic procedure parameters Connectivity NR, Connected without release On, Test Mode On and Test Loop Function On according to TS 38.508-1 [10] clause 4.5. Message contents are defined in clause 6.3.4.4.4.3.
6.3.4.4.4.2 Test procedure
The procedure is separated in two subtests to verify PUCCH and PUSCH aggregate power control tolerance respectively. The uplink transmission patterns are described in Figure 6.3.4.4.4.2-1.
Figure 6.3.4.4.4.2-1: Test uplink transmission
1. PUCCH subtest:
1.1. Set the UE in the Tx beam peak direction found with a 3D EIRP scan as performed in Annex K.1.1.
1.2. SS activates the UE Beamlock Function (UBF) by performing the procedure as specified in TS 38.508-1 [10] clause 4.9.2 using condition Tx only.
1.3. The SS transmits PDSCH via PDCCH DCI format 1_1 for C_RNTI to transmit the DL RMC according to Table 6.3.4.4.4.1-1. The SS sends downlink MAC padding bits on the DL RMC. The transmission of PDSCH will make the UE send uplink ACK/NACK using PUCCH. Send uplink power control commands for PUCCH to the UE using 1dB power step size to ensure that the UE output power measured by the test system is within PW of the target power level specified in Table 6.3.4.4.4.2-1 according to the power class with power ID = 1. PW is the power window according to Table 6.3.4.4.4.2-2 for the carrier frequency f and the channel bandwidth BW.
1.4. Every 10 sub-frames (10ms) transmit to the UE downlink PDSCH MAC padding bits as well as 0 dB TPC command for PUCCH via the PDCCH to make the UE transmit ACK/NACK on the PUCCH for 1 sub-frame (1ms). The downlink transmission is scheduled in the appropriate slots to make the UE transmit PUCCH as described in Figure 6.3.4.4.4.2-1.
1.5. Measure the UE EIRP of 3 consecutive PUCCH transmissions in the Tx beam peak direction of in the measurement bandwidth specified in Table 6.3.1.5-1 and Table 6.3.1.5-2 to verify the UE transmitted PUCCH power is maintained within 21ms. EIRP test procedure is defined in Annex K. EIRP is calculated considering both polarizations, theta and phi. For TDD slots with transient periods are not under test.
1.6. SS deactivates the UE Beamlock Function (UBF) by performing the procedure as specified in TS 38.508-1 [10] clause 4.9.3.
1.7. Repeat test steps 1.2 to 1.6 for measurement for power ID = 2 in Table 6.3.4.4.4.2-1.
2. PUSCH subtest:
2.1. Set the UE in the Tx beam peak direction found with a 3D EIRP scan as performed in Annex K.1.1.
2.2. SS activates the UE Beamlock Function (UBF) by performing the procedure as specified in TS 38.508-1 [10] clause 4.9.2 using condition Tx only.
2.3. The SS sends uplink scheduling information via PDCCH DCI format 0_1 for C_RNTI to schedule the PUSCH. Since the UE has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL RMC. Send uplink power control commands for PUSCH to the UE using 1dB power step size to ensure that the UE output power measured by the test system is within PW of the target power level specified in Table 6.3.4.4.4.2-1 according to the power class with power ID = 1. PW is the power window according to Table 6.3.4.4.4.2-2 for the carrier frequency f and the channel bandwidth BW.
2.4. Every 10 sub-frames (10ms) schedule the UE’s PUSCH data transmission for 1 sub-frame (1ms)and transmit 0 dB TPC command for PUSCH via the PDCCH to make the UE transmit PUSCH. The uplink transmission patterns are described in Figure 6.3.4.4.4.2-1.
2.5. Measure the UE EIRP of 3 consecutive PUSCH transmissions in the Tx beam peak direction of in the measurement bandwidth specified in Table 6.3.1.5-1 and Table 6.3.1.5-2 to verify the UE transmitted PUSCH power is maintained within 21ms. EIRP test procedure is defined in Annex K. EIRP is calculated considering both polarizations, theta and phi. For TDD slots with transient periods are not under test.
2.6. SS deactivates the UE Beamlock Function (UBF) by performing the procedure as specified in TS 38.508-1 [10] clause 4.9.3.
2.7. Repeat test steps 2.2 to 2.6 for measurement for power ID = 2 in Table 6.3.4.4.4.2-1.
