6.4.2.1_1.1 Test Purpose
The purpose of this test is to verify that the reported rank indicator accurately represents the channel rank. The accuracy of RI reporting is determined by the relative increase of the throughput obtained when transmitting based on the reported rank compared to the case for which a fixed rank is used for transmission.
6.4.2.1_1.2 Test applicability
This test applies to all types of NR UE release 15 and forward.
This test also applies to all types of EUTRA UE release 15 and forward supporting EN-DC.
6.4.2.1_1.3 Minimum Conformance Requirements
The minimum performance requirement in Table 6.4.2.1_1.3-2 is defined as:
a) The ratio of the throughput obtained when transmitting based on UE reported RI and that obtained when transmitting with fixed rank 1 shall be ≥ ;
b) The ratio of the throughput obtained when transmitting based on UE reported RI and that obtained when transmitting with fixed rank 2 shall be ≥ ;
For the parameters specified in Table 6.4.2.1_1.3-1, and using the downlink physical channels specified in Annex C.3.1, the minimum requirements are specified in Table 6.4.2.1_1.3-2.

This test applies to all types of NR UE release 15 and forward.
This test also applies to all types of EUTRA UE release 15 and forward supporting EN-DC.
6.4.2.2_1.3 Minimum Conformance Requirements
The minimum performance requirement in Table 6.4.2.2_1.3-2 is defined as:
a) The ratio of the throughput obtained when transmitting based on UE reported RI and that obtained when transmitting with fixed rank 1 shall be ≥ ;
b) The ratio of the throughput obtained when transmitting based on UE reported RI and that obtained when transmitting with fixed rank 2 shall be ≥ ;

7. The SS shall send PDSCH via PDCCH DCI format 1_1 for C_RNTI to transmit the DL RMC according to the UE reported CQI (wideband CQI), PMI and RI. The SS sends downlink MAC padding bits on the DL RMC. Measure
according to Annex G.3.3.
If the ratio (
/ 
) satisfies the requirement in Table 6.4.2.2_1.5-1, then pass the UE for this test and go to step 8. Otherwise, declare a FAIL verdict.
8. If all tests have not been done, then repeat the same procedure (steps 1 to 7) with test conditions according to the Table 6.4.2.2_1.3-2 for the other Tests as appropriate. Otherwise, declare a PASS verdict.

6.4.3.1_1.4 Test Description
6.4.3.1_1.4.1 Initial conditions
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, test channel bandwidths and sub-carrier spacing based on NR operating bands specified in Table 5.3.5-1 of 38.521-1.
Configurations of PDSCH and PDCCH before measurement are specified in Annex C.
Test Environment: Normal as defined in TS 38.508 [6] clause 4.1.
Frequencies to be tested: Mid Range as defined in TS 38.508 [6] clause 5.2.2.
For EN-DC within FR1 operation, setup the LTE link according to Annex D
1. Connect the SS, the faders and AWGN noise source to the UE antenna connectors as shown in TS 38.508-1 [6] Annex A, in Figure A.3.1.7.4 or A.3.1.7.5 for TE diagram and section A.3.2.5 for UE diagram.
2. The parameter settings for the cell are set up according to Table 6.1.2-1, Table 6.4.3.1_1.3-1 as appropriate.
3. Downlink signals for NR cell are initially set up according to Annexes C.0, C.1, C.2, C.3.1 and uplink signals according to Annexes G.0, G.1, G.2, G.3.1 of TS 38.521-1 [7].
4. Propagation conditions for the NR cell are set according to Annex B.0.
5. Ensure the UE is in state RRC_CONNECTED with generic procedure parameters Connectivity NR, Connected without release On and Test Mode ON for SA or (EN-DC, DC bearer MCG and SCG, Connected without release On for NSA according to TS 38.508-1 [6] clause 4.5. Message contents are defined in clause 6.4.3.1_1.4.3.
6.4.3.1_1.4.2 Test procedure
1. Set the parameters of bandwidth, reference channel, the propagation condition, antenna configuration, antenna correlation, Codebook configuration, Beamforming Model, RI configuration and SNR according to Table 6.4.3.1_1.3-1 as appropriate.
2. The SS shall send PDSCH via PDCCH DCI format 1_1 for C_RNTI to transmit the DL RMC according to the UE reported CQI (wideband CQI), PMI and fixed RI as defined in Table 6.4.3.1_1.3-1. The SS sends downlink MAC padding bits on the DL RMC. Measure the
according to Annex G.3. 3.
3. Propagation conditions are set according to Annex B.2. 4
4. The SS shall transmit an RRC Connection Reconfiguration message to set codebookSubsetRestriction as for UE reported RI according to Table 6.4.3.1_1.3-1.
5. The UE shall transmit RRC Connection Reconfiguration Complete message.
6. Propagation conditions are set according to Table 6.4.3.1_1.3-1.
7. The SS shall send PDSCH via PDCCH DCI format 1_1 for C_RNTI to transmit the DL RMC according to the UE reported CQI (wideband CQI), PMI and RI. The SS sends downlink MAC padding bits on the DL RMC. Measure
according to Annex G.3.3.
If the ratio (
/ 
) satisfies the requirement in Table 6.4.3.1_1.5-1, then pass the UE for this test and go to step 8. Otherwise, declare a FAIL verdict.
8. If all tests have not been done, then repeat the same procedure (steps 1 to 7) with test conditions according to the Table 6.4.3.1_1.3-2 for the other Tests as appropriate. Otherwise, declare a PASS verdict.

The normative reference for this requirement is TS 38.101-4 [2] clause 6.4.3.2.
6.4.3.2_1.4 Test Description
6.4.3.2_1.4.1 Initial conditions
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, test channel bandwidths and sub-carrier spacing based on NR operating bands specified in Table 5.3.5-1 of 38.521-1[7].
Configurations of PDSCH and PDCCH before measurement are specified in Annex C.
Test Environment: Normal as defined in TS 38.508-1 [6] clause 4.1.
Frequencies to be tested: Mid Range as defined in TS 38.508-1 [6] clause 5.2.2.
For EN-DC within FR1 operation, setup the LTE link according to Annex D
1. Connect the SS, the faders and AWGN noise source to the UE antenna connectors as shown in TS 38.508-1 [6] Annex A, in Figure A.3.1.7 for TE diagram and section A.3.2.5 for UE diagram.
2. The parameter settings for the cell are set up according to Table 6.1.2-1 and Table 6.4.3.2_1.3-1 as appropriate.
3. Downlink signals for NR cell are initially set up according to Annexes C.0, C.1, C.2, C.3.1 and uplink signals according to Annexes G.0, G.1, G.2, G.3.1 of TS 38.521-1 [7].
4. Propagation conditions are set according to Annex B.0.
5. Ensure the UE is in state RRC_CONNECTED with generic procedure parameters Connectivity NR, Connected without release On and Test Mode ON for SA or EN-DC, DC bearer MCG and SCG, Connected without release On and Test Mode ON for NSA according to TS 38.508-1 [6] clause 4.5. Message contents are defined in clause 6.4.3.2_1.4.3.
6.4.3.2_1.4.2 Test procedure
1. Set the parameters of bandwidth, reference channel, the propagation condition, antenna configuration, antenna correlation, Codebook configuration, Beamforming Model, RI configuration and SNR according to Table 6.4.3.2_1.3-1 as appropriate.
2. The SS shall send PDSCH via PDCCH DCI format 1_1 for C_RNTI to transmit the DL RMC according to the UE reported CQI (wideband CQI), PMI and fixed RI as defined in Table 6.4.3.2_1.3-1. The SS sends downlink MAC padding bits on the DL RMC. Measure theaccording to Annex G.3.3.
3. Propagation conditions are set according to Annex B.2.
4. The SS shall transmit an RRC Connection Reconfiguration message to set codebookSubsetRestriction as for UE reported RI according to Table 6.4.3.2_1.3-1.
5. The UE shall transmit RRC Connection Reconfiguration Complete message.
6. Propagation conditions are set according to Table 6.4.3.2_1.3-1.
7. The SS shall send PDSCH via PDCCH DCI format 1_1 for C_RNTI to transmit the DL RMC according to the UE reported CQI (wideband CQI), PMI and RI. The SS sends downlink MAC padding bits on the DL RMC. Measure
according to Annex G.3.3.
If the ratio (
/ 
) satisfies the requirement in Table 6.4.3.2_1.5-1, then pass the UE for this test and go to step 8. Otherwise, declare a FAIL verdict.
8. If all tests have not been done, then repeat the same procedure (steps 1 to 7) with test conditions according to the Table 6.4.3.2_1.3-2 for the other Tests as appropriate. Otherwise, declare a PASS verdict.
