6.4D Transmit signal quality for UL MIMO

38.521-23GPPNRPart 2: Range 2 StandaloneRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification

6.4D.0 General

For a UE supporting UL MIMO, the transmit modulation quality requirements in clause 6.4 apply but with all references to sub-clauses 6.3.1.3.x in clause 6.4 redirected to sub-clauses 6.3D.1.3.x, where ‘x’ depends on power class. The requirements apply when the UE is configured for 2-layer UL MIMO transmission as specified in Table 6.2D.1.0-1.

The requirement may alternatively be verified in each of the single layer UL MIMO configurations as specified in Table 6.4D.0-1. In this case, the transmit modulation quality requirements in clause 6.4 apply without modification.

6.4D.1.4.2 Test procedure

1. Retrieve the LO position from the parameter txDirectCurrentLocation in UplinkTxDirectCurrent IE.

2. SS transmits PDSCH via PDCCH DCI format 1_1 for C_RNTI to transmit the DL RMC according to Table 6.4D.1.4.1-1. The SS sends downlink MAC padding bits on the DL RMC.

3. 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 6.4D.1.4.1-1. Since the UL has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL RMC.

5. Set the UE in the Inband Tx beam peak direction and apply the associated polarization for the DL, both found with a 3D EIRP scan as performed in Annex K.1.1. Connect the SS (System Simulator) with the DUT through the measurement antenna with polarization reference PolLink to form the TX beam towards the TX beam peak direction and respective polarization. Allow at least BEAM_SELECT_WAIT_TIME (NOTE 1) for the UE Tx beam selection to complete.

4. Send continuously uplink power control "up" commands to the UE in every uplink scheduling information to the UE so that the UE transmits at PUMAX level for the duration of the test. Allow at least 200ms starting from the first TPC Command for the UE to reach PUMAX level. Allow at least BEAM_SELECT_WAIT_TIME (NOTE 1) for the UE Tx beam selection to complete.

7. Measure the Frequency Error using Global In-Channel Tx-Test (Annex E) at each layer for the θ- and φ-polarization of the UL. For TDD, only slots consisting of only UL symbols are under test.

NOTE 1: The BEAM_SELECT_WAIT_TIME default value is defined in Annex K.1.1.

6.4D.2.1.1 Test purpose

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.

6.4D.2.1.2 Test applicability

This test case applies to all types of NR UE release 15 and forward that support UL MIMO.

6.4D.2.1.3 Minimum conformance requirements

For a UE supporting UL MIMO, the RMS average of the basic EVM measurements for the average EVM case, and for the reference signal EVM case, for the different modulation schemes shall not exceed the values specified in Table 6.4D.2.1.3-1 for the parameters defined in Table 6.4D.2.1.3-2 or Table 6.4D.2.1.3-3 depending on UE power class. For EVM evaluation purposes, all 13 PRACH preamble formats and all 5 PUCCH formats are considered to have the same EVM requirement as QPSK modulated.

6.4D.2.3 In-band emissions for UL MIMO

Editor’s note: This clause is incomplete. The following aspects are either missing or not yet determined:

– OTA test procedure for UL MIMO is still under investigation.

– Test config table is FFS.

– TP analysis is FFS.

– Measurement Uncertainty and Test Tolerances are FFS.

6.4D.2.3.1 Test purpose

The purpose of this test is to exercise the UE transmitter to verify its modulation quality in terms of in-band emissions.

6.4D.2.3.2 Test applicability

This test case applies to all types of NR UE release 15 and forward that support UL MIMO.

6.4D.2.3.3 Minimum conformance requirements

For a UE supporting UL MIMO, the in-band emission is defined as the average across 12 sub-carriers and as a function of the RB offset from the edge of the allocated UL transmission bandwidth. The in-band emission is measured as the ratio of the UE output power in a non–allocated RB to the UE output power in an allocated RB. The IBE requirement does not apply if UE declares support for mpr-PowerBoost-FR2-r16, UL transmission excluding Pi/2 BPSK is such that MPRf,c = 0 and when NS_200 applies, and the network configures the UE to operate with mpr-PowerBoost-FR2-r16.

The basic in-band emissions measurement interval is identical to that of the EVM test.

The requirement is verified with the test metric of In-band emission (Link=TX beam peak direction, Meas=Link angle).

The relative in-band emission shall not exceed the values specified in Table 6.4D.2.3.3-1 for power class 1 UEs.

The average of the in-band emission measurement over 10 sub-frames shall not exceed the values specified in Table 6.4D.2.3.3-1 for power class 1, Table 6.4D.2.3.3-2 for power class 2, Table 6.4D.2.3.3-3 for power class 3 and Table 6.4D.2.3.3-4 for power class 4 UEs.

6.4D.2.3.4.2 Test procedure

Test procedure for PUSCH:

1.1 Retrieve the LO position from the parameter txDirectCurrentLocation in UplinkTxDirectCurrent IE.

1.2 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 6.4D.2.3.4.1-1. Since the UE has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL RMC.

1.3 Set the UE in the Inband 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 2) for the UE Tx beam selection to complete.

1.4 Send the appropriate TPC commands in the uplink scheduling information to the UE until UE output power is Preq + PW ± PW, where Preq is the power level specified in Tables 6.4D.2.3.4.2-1 according to the power class with power ID = 1. PW is the power window according to Table 6.4D.2.3.4.2-2 for the carrier frequency f and the channel bandwidth BW. Allow at least BEAM_SELECT_WAIT_TIME (NOTE 2) for the UE Tx beam selection to complete.

1.5 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 TxRx.

1.6 Measure In-band emission IEθ, IEφ using Global In-Channel Tx-Test (Annex E) for the θ- and φ-polarizations, respectively. For TDD, only slots consisting of only UL symbols are under test. Calculate IE = IEθ + IEφ, where the calculation is based on linear power ratios.

1.7 SS deactivates the UE Beamlock Function (UBF) by performing the procedure as specified in TS 38.508-1 [10] clause 4.9.3.

1.8 Repeat steps 1.3 through 1.6 until In-band emissions have been measured for all power IDs in Table 6.4D.2.3.4.2-1.

NOTE 1: When switching to DFT-s-OFDM waveform, as specified in Table 6.4D.2.3.4.1-1, send an NR RRCReconfiguration message according to TS 38.508-1 [10] clause 4.6.3 Table 4.6.3-118 PUSCH-Config with TRANSFORM_PRECODER_ENABLED condition.

2.3 Set the UE in the Inband 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.

2.4 Send the appropriate TPC commands in the uplink scheduling information for PUCCH to the UE until UE output power is Preq + PW ± PW, where Preq is the power level specified in Tables 6.4D.2.3.4.2-1 according to the power class with power ID = 1. PW is the power window according to Table 6.4D.2.3.4.2-2 for the carrier frequency f and the channel bandwidth BW.
