9.3.7.1.4.2 Test procedure
1. Set the parameters of bandwidth, reference Channel, the propagation condition, antenna configuration and the SNR according to Table 9.3.7.1.5-2 as appropriate.
For Test1
2. The SS shall transmit PDSCH via PDCCH DCI format 1B for C_RNTI to transmit the DL RMC according to the wideband and subband CQI value sent by the UE and according to the wideband and subband PMI value sent by the UE. Continue transmission of the PDSCH until 2000 wideband CQI reports, wideband PMI reports, full-size subband CQI reports, and full-size subband PMI reports for each full-size subband have been gathered. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission in subframe #0 and subframe #5 to carry the PUSCH CQI feedback via PDCCH DCI format 0 with CQI request bit set to 1 and I_MCS=29 and N_PRB allocated to be less or equal to 4. In this process the SS collects wideband CQI reports every 5 ms and also cases where UE transmits nothing in its CQI timing are counted as wideband CQI and full-size subband CQI reports.
3. The SS shall transmit PDSCH via PDCCH DCI format 1B for C_RNTI to transmit the DL RMC according to the wideband CQI value and wideband PMI value. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission in subframe #0 and subframe #5 to carry the PUSCH 3-1 CQI feedback via PDCCH DCI format 0 with CQI request bit set to 1 and I_MCS=29 and N_PRB allocated to be less or equal to 4. Measure the average throughput according to Annex G.5.3. Declare the throughput as
.
4. The SS sends uplink scheduling information via PDCCH DCI format 0 with CQI request bit to 0 to schedule UL RMC in every subframe (Table A.4.1-1).
5. The SS shall transmit an RRC Connection Reconfiguration message to set reporting mode according to Table 9.3.7.1.3-1.
6. The UE shall transmit RRC Connection Reconfiguration Complete message.
7. The SS shall transmit PDSCH via PDCCH DCI format 1B for C_RNTI to transmit the DL RMC according to the wideband CQI value and subband PMI value. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission in subframe #0 and subframe #5 to carry the PUSCH 3-2 CQI feedback via PDCCH DCI format 0 with CQI request bit set to 1 and I_MCS=29 and N_PRB allocated to be less or equal to 4. Measure the average throughput according to Annex G.5.3. Declare the throughput as 
.
8. If the ratio (
/
) ≥ αwhich is specified in Table 9.3.7.1.5-1, pass the UE for this test and go to step 16. Otherwise, go to step 15.
For Test2
9. The SS shall transmit PDSCH via PDCCH DCI format 2C for C_RNTI to transmit the DL RMC according to the wideband and subband CQI value sent by the UE and according to the wideband and subband PMI value sent by the UE. Continue transmission of the PDSCH until 2000 wideband CQI reports, wideband PMI reports, full-size subband CQI reports, and full-size subband PMI reports for each full-size subband have been gathered. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission in subframe #0 and subframe #5 to carry the PUSCH CQI feedback via PDCCH DCI format 0 with CQI request bit set to 1 and I_MCS=29 and N_PRB allocated to be less or equal to 4. In this process the SS collects wideband CQI reports every 5 ms and also cases where UE transmits nothing in its CQI timing are counted as wideband CQI and full-size subband CQI reports.
10. The SS shall send PDSCH via PDCCH DCI format 2C for C_RNTI to transmit the DL RMC according to the wideband CQI value and subband PMI value in each available downlink transmission instance randomly selected full-size subband. Note that each full-size subband is selected in equal probability. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission in subframe #0 and subframe #5 to carry the PUSCH 1-2 CQI feedback via PDCCH DCI format 0 with CQI request bit set to 1 and I_MCS=29 and N_PRB allocated to be less or equal to 4. Measure the average throughput according to Annex G.5.3. Declare the throughput as 
.
11. The SS sends uplink scheduling information via PDCCH DCI format 0 with CQI request bit to 0 to schedule UL RMC in every subframe (Table A.4.1-1).
12. The SS shall transmit an RRC Connection Reconfiguration message to set reporting mode according to Table 9.3.7.1.3-1.

The SS shall transmit PDSCH via PDCCH DCI format 2C for C_RNTI to transmit the DL RMC according to the highest UE reported full-size subband CQI value and ull-size subband PMI value in one full-size subband selected among the subbands in which UE reports the highest full-size subband CQI and full-size subband PMI. Subband differential CQI offset level is selected from {0, 1, 2, -1}. Note that the SS shall send PDSCH in the same full-size subband until next UE report is available. In case when same full-size subbands are reported subsequently as subbands with highest full-size subband CQI, the SS shall select for transmission a different subband with respect to the last selection. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission in subframe #0 and subframe #5 to carry the PUSCH 3-2 CQI feedback via PDCCH DCI format 0 with CQI request bit set to 1 and I_MCS=29 and N_PRB allocated to be less or equal to 4. Measure the average throughput according to Annex G.5.3. Declare the throughput as 
. If the ratio (
/
) ≥ βwhich is specified in Table 9.3.7.1.5-1, pass the UE for this test and go to step 16. Otherwise, go to step15.
15. If both SNR points of the test have not been tested, then repeat the same procedure (steps 1 to 14) for the other SNR point as appropriate. Otherwise fail the UE.
16. If both tests have not been done, then repeat the same procedure (steps 1 to 15) with test conditions according to the Table 9.3.7.1.3-1 for the other Test as appropriate. Otherwise pass the UE.

1. Connect the SS, faders and AWGN noise source to the UE antenna connector (s) as shown in TS 36.508 [7] Annex A, Figure A.11 for UE with 2Rx RF band and Annex A, Figure A.11a for 4Rx capable UE without any 2Rx RF bands.
2. The parameter settings for the cell are set up according to Table 9.3.7.2.3-1.
3. Downlink signals are initially set up according to Annex C.0, C.1 and Annex C.3.2, and uplink signals according to Annex H.1 and H.3.2.
4. Propagation conditions are set according to Annex B.0.
5. Ensure the UE is in State 3A-RF according to TS 36.508 [7] clause 5.2A.2. Message contents are defined in clause 9.3.7.2.4.3.
9.3.7.2.4.2 Test procedure
1. Set the parameters of bandwidth, reference Channel, the propagation condition, antenna configuration and the SNR according to Table 9.3.7.2.5-2 as appropriate.
For Test1
2. The SS shall transmit PDSCH via PDCCH DCI format 1B for C_RNTI to transmit the DL RMC according to the wideband and subband CQI value sent by the UE and according to the wideband and subband PMI value sent by the UE. Continue transmission of the PDSCH until 2000 wideband CQI reports, wideband PMI reports, full-size subband CQI reports, and full-size subband PMI reports for each full-size subband have been gathered. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission in subframe #3 and subframe #8 to carry the PUSCH CQI feedback via PDCCH DCI format 0 with CQI request bit set to 1 and I_MCS=29 and N_PRB allocated to be less or equal to 4. In this process the SS collects wideband CQI reports every 5 ms and also cases where UE transmits nothing in its CQI timing are counted as wideband CQI and full-size subband CQI reports.
3. The SS shall transmit PDSCH via PDCCH DCI format 1B for C_RNTI to transmit the DL RMC according to the wideband CQI value and wideband PMI value. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission in subframe #3 and subframe #8 to carry the PUSCH 3-1 CQI feedback via PDCCH DCI format 0 with CQI request bit set to 1 and I_MCS=29 and N_PRB allocated to be less or equal to 4. Measure the average throughput according to Annex G.5.3. Declare the throughput as
.
4. The SS sends uplink scheduling information via PDCCH DCI format 0 with CQI request bit to 0 to schedule UL RMC in subframe#3 and #8 (Table A.4.1-2).
5. The SS shall transmit an RRC Connection Reconfiguration message to set reporting mode according to Table 9.3.7.2.3-1.
6. The UE shall transmit RRC Connection Reconfiguration Complete message.
7. The SS shall transmit PDSCH via PDCCH DCI format 1B for C_RNTI to transmit the DL RMC according to the wideband CQI value and subband PMI value. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission in subframe #3 and subframe #8 to carry the PUSCH 3-2 CQI feedback via PDCCH DCI format 0 with CQI request bit set to 1 and I_MCS=29 and N_PRB allocated to be less or equal to 4. Measure the average throughput according to Annex G.5.3. Declare the throughput as 
.
8. If the ratio (
/
) ≥ αwhich is specified in Table 9.3.7.2.5-1, pass the UE for this test and go to step 16. Otherwise, go to step 15.
For Test2
9. The SS shall transmit PDSCH via PDCCH DCI format 2C for C_RNTI to transmit the DL RMC according to the wideband and subband CQI value sent by the UE and according to the wideband and subband PMI value sent by the UE. Continue transmission of the PDSCH until 2000 wideband CQI reports, wideband PMI reports, full-size subband CQI reports, and full-size subband PMI reports for each full-size subband have been gathered. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission in subframe #3 and subframe #8 to carry the PUSCH CQI feedback via PDCCH DCI format 0 with CQI request bit set to 1 and I_MCS=29 and N_PRB allocated to be less or equal to 4. In this process the SS collects wideband CQI reports every 5 ms and also cases where UE transmits nothing in its CQI timing are counted as wideband CQI and full-size subband CQI reports.
10. The SS shall send PDSCH via PDCCH DCI format 2C for C_RNTI to transmit the DL RMC according to the wideband CQI value and subband PMI value in each available downlink transmission instance randomly selected full-size subband. Note that each full-size subband is selected in equal probability. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission in subframe #3 and subframe #8 to carry the PUSCH 1-2 CQI feedback via PDCCH DCI format 0 with CQI request bit set to 1 and I_MCS=29 and N_PRB allocated to be less or equal to 4. Measure the average throughput according to Annex G.5.3. Declare the throughput as 
.
11. The SS sends uplink scheduling information via PDCCH DCI format 0 with CQI request bit to 0 to schedule UL RMC in subframe#3 and #8 (Table A.4.1-2).
12. The SS shall transmit an RRC Connection Reconfiguration message to set reporting mode according to Table 9.3.7.2.3-1.
13. The UE shall transmit RRC Connection Reconfiguration Complete message.
14. The SS shall transmit PDSCH via PDCCH DCI format 2C for C_RNTI to transmit the DL RMC according to the highest UE reported full-size subband CQI value and ull-size subband PMI value in one full-size subband selected among the subbands in which UE reports the highest full-size subband CQI and full-size subband PMI. Subband differential CQI offset level is selected from {0, 1, 2, -1}. Note that the SS shall send PDSCH in the same full-size subband until next UE report is available. In case when same full-size subbands are reported subsequently as subbands with highest full-size subband CQI, the SS shall select for transmission a different subband with respect to the last selection. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission in subframe #3 and subframe #8 to carry the PUSCH 3-2 CQI feedback via PDCCH DCI format 0 with CQI request bit set to 1 and I_MCS=29 and N_PRB allocated to be less or equal to 4. Measure the average throughput according to Annex G.5.3. Declare the throughput as 
. If the ratio (
/
) ≥ βwhich is specified in Table 9.3.7.2.5-1, pass the UE for this test and go to step 16. Otherwise, go to step 15.
15. If both SNR points of the test have not been tested, then repeat the same procedure (steps 1 to 14) for the other SNR point as appropriate. Otherwise fail the UE.
16. If both tests have not been done, then repeat the same procedure (steps 1 to 15) with test conditions according to the Table 9.3.7.2.3-1 for the other Test as appropriate. Otherwise pass the UE.
