9.12.1.1.4 Test description
9.12.1.1.4.1 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.
Configurations of PDSCH and PDCCH before measurement are specified in Annex C.2.
Test Environment: Normal as defined in TS 36.508 [7] clause 4.1.
Frequencies to be tested: Mid Range as defined in TS 36.508 [7] clause 4.3.1.1.
Channel Bandwidths to be tested: 10MHz for tests defined in Table 9.12.1.1.3-1 and Table 9.12.1.1.3-2, as defined in TS 36.508 [7] clause 4.3.1.1
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.9 for UE with 2Rx RF band and Annex A, Figure A.9a for 4Rx capable UE without any 2Rx RF bands.
2. The parameter settings for the cell are set up according to Table 9.12.1.1.3-1 for slot-PDSCH and Table 9.12.1.1.3-2 for subslot-PDSCH.
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.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 9.12.1.1.4.3.
9.12.1.1.4.2 Test procedure
1. Set the parameters of bandwidth, the propagation condition, antenna configuration and measurement channel according to Table 9.12.1.1.5-2 for slot-PDSCH and Table 9.12.1.1.5-3 for subslot-PDSCH as appropriate.
2. The SS shall transmit slot/subslot-PDSCH via SPDCCH DCI format 7-1C for C_RNTI to transmit the DL RMC according to CQI value 8 and keep it regardless of the wideband sent by the UE. Continue transmission of the slot-PDSCH until 2000 wideband CQI reports have been gathered. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission every 5 ms to carry the slot-PUSCH CQI feedback via SPDCCH DCI format 7-0A with CQI request bit set to 1. 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.
3. Set up a relative frequency distribution for the reported wideband CQI-values, reported. Calculate the median value (wideband Median CQI is the wideband CQI that is at or crosses 50% distribution from the lower wideband CQI side). This CQI-value is declared as wideband Median CQI value.
4. If less than 2000*(100-)/100 of the wideband CQI values are in the range (Median CQI – 1) ≤ Median CQI ≤ ( Median CQI + 1) then continue with step 5, otherwise go to step 7.
5. The SS shall transmit slot/subslot-PDSCH via SPDCCH DCI format 7-1C for C_RNTI to transmit the DL RMC according to the wideband median-CQI value regardless of UE wideband CQI report. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via SPDCCH DCI format 7-0A with CQI request bit set to 1 to schedule UL RMC every 5 ms. Measure the average throughput according to Annex G.5.3. Declare the throughput as .
6. The SS shall transmit slot/subslot-PDSCH via SPDCCH DCI format 7-1C for C_RNTI to transmit the DL RMC according to the wideband CQI value reported from UE. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via SPDCCH DCI format 7-0A with CQI request bit set to 0 to schedule UL RMC every 5 ms. Measure the average throughput according to Annex G.5.3. Declare the throughput as . For any slot/subslot-PDSCH transmitted by the SS, record the associated ACK, NACK and statDTX responses. The responses are then filtered as follows: for the sequence of responses for each HARQ process, discard all the statDTX responses. If the ratio (
/
) ≥ and ratio (NACK /(ACK + NACK)) is greater or equal to 0.02, then pass the UE for this test and go to step 8. Otherwise go to step 7.
7. If both SNR points of the test have not been tested, then repeat the same procedure (steps 1 to 6) for the other SNR point as appropriate. Otherwise fail the UE.
8. If both tests have not been done, then repeat the same procedure (steps 1 to 7) with test conditions according to the table 9.12.1.1.3-1 for slot-PDSCH or table 9.12.1.1.3-2 for subslot-PDSCH for the other Test as appropriate. Otherwise pass the UE.
Note: For UEs indicating support of combination-22-r15 or combination-27-r15, Test for subslot-PDSCH in Table 9.12.1.1.3-2 is executed. Otherwise Test for slot-PDSCH in Table 9.12.1.1.3-1 is excuted.

1. Connect the SS to the UE antenna connector (s) as shown in TS 36.508 [7] Annex A, Figure A.9.
2. The parameter settings for the cell are set up according to Table 9.12.1.2.3-1.
3. Downlink signals are initially set up according to Annex C0, C.1 and Annex C.3.2, and uplink signals according to Annex 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 9.12.1.2.4.3.
9.12.1.2.4.2 Test procedure
1. Set the parameters of bandwidth, the propagation condition, antenna configuration and measurement channel according to Table 9.12.1.2.3-1 as appropriate.
2. The SS shall transmit slot-PDSCH via SPDCCH DCI format 7-1C for C_RNTI to transmit the DL RMC according to CQI value 8 and keep it regardless of the wideband sent by the UE. Continue transmission of the slot-PDSCH until 2000 wideband CQI reports have been gathered. The SS sends downlink MAC padding bits on the DL RMC. SS schedules the UL transmission every 5 ms to carry the slot-PUSCH CQI feedback via SPDCCH DCI format 7-0A with CQI request bit set to 1. 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.
3. Set up a relative frequency distribution for the reported wideband CQI-values, reported. Calculate the median value (wideband Median CQI is the wideband CQI that is at or crosses 50% distribution from the lower wideband CQI side). This CQI-value is declared as wideband Median CQI value.
4. If less than 2000*(100-)/100 of the wideband CQI values are in the range (Median CQI – 1) ≤ Median CQI ≤ (Median CQI + 1) then continue with step 5, otherwise go to step 7.
5. The SS shall transmit slot-PDSCH via SPDCCH DCI format 7-1C for C_RNTI to transmit the DL RMC according to the wideband median-CQI value regardless of UE wideband CQI report. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via SPDCCH DCI format 7-0A with CQI request bit set to 1 to schedule UL RMC every 5 ms. Measure the average throughput for a duration sufficient to achieve statistical significance according to Annex G.5.3. Declare the throughput as .
6. The SS shall transmit slot-PDSCH via SPDCCH DCI format 7-1C for C_RNTI to transmit the DL RMC according to the wideband CQI value reported from UE. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via SPDCCH DCI format 7-0A with CQI request bit set to 1 to schedule UL RMC every 5 ms. Measure the average throughput for a duration sufficient to achieve statistical significance according to Annex G.5.3. Declare the throughput as . For any slot-PDSCH transmitted by the SS, record the associated ACK, NACK and statDTX responses. The responses are then filtered as follows: for the sequence of responses for each HARQ process, discard all the statDTX responses. If the ratio (
/
) ≥ and ratio (NACK /(ACK + NACK )) is greater or equal to 0.02, then pass the UE and go to step 8. Otherwise go to step 7.
7. If both SNR points of the test have not been tested, then repeat the same procedure (steps 1 to 6) for the other SNR point as appropriate. Otherwise fail the UE.
8. If both tests have not been done, repeat the same procedure (steps 1 to 7) with test conditions according to the table 9.12.1.2.3-1 for the other test as appropriate.

9.12.2.1.4.2 Test procedure
1. Set the parameters of bandwidth, the propagation condition, antenna configuration and measurement channel according to Table 9.12.2.1.5-2 and Table 9.12.2.1.5-3 as appropriate.
2. The SS shall transmit slot/subslot-PDSCH via SPDCCH DCI format 7-1F for C_RNTI to transmit the DL RMC according to CQI value 8 and keep it regardless of the wideband CQI value sent by the UE. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via SPDCCH DCI format 7-0A with CQI request bit set to 1 to schedule UL RMC every 5 ms. Continue transmission of the slot/subslot-PDSCH until 2000 wideband CQI reports have been gathered. 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 reports.
3. Set up a relative frequency distribution for the reported wideband CQI-values, reported. Calculate the median value (wideband Median CQI is the wideband CQI that is at or crosses 50% distribution from the lower wideband CQI side). This CQI-value is declared as wideband Median CQI value.
4. If less than (100-)/100*2000 of the wideband CQI values are in the range (Median CQI – 1) ≤ Median CQI ≤ ( Median CQI + 1) then continue with step 5, otherwise go to step 7.
5. The SS shall transmit slot/subslot-PDSCH via SPDCCH dci format 7-1F for C_RNTI to transmit the DL RMC according to the wideband median-CQI value regardless of UE wideband CQI report. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via SPDCCH DCI format 7-0A with CQI request bit set to 1 to schedule UL RMC in every 5 ms. Measure the average throughput according to Annex G.5.3. Declare the throughput as .
6. The SS shall transmit slot/subslot-PDSCH via SPDCCH DCI format 7-1F for C_RNTI to transmit the DL RMC according to the wideband CQI value reported from UE. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via SPDCCH DCI format 7-0A with CQI request bit set to 1 to schedule UL RMC every 5 ms. Measure the average throughput according to Annex G.5.3. Declare the throughput as . For any slot/subslot-PDSCH transmitted by the SS, record the associated ACK, NACK and statDTX responses. The responses are then filtered as follows: for the sequence of responses for each HARQ process, discard all the statDTX responses. If the ratio (
/
) ≥ and ratio (NACK /(ACK + NACK)) is greater or equal to 0.02, then pass the UE for this test and go to step 8. Otherwise go to step 7.
7. If both SNR points of the test have not been tested, then repeat the same procedure (steps 1 to 6) for the other SNR point as appropriate. Otherwise fail the UE.

9.12.2.2.4 Test description
9.12.2.2.4.1 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.
Configurations of PDSCH and PDCCH before measurement are specified in Annex C.2.
Test Environment: Normal as defined in TS 36.508 [7] clause 4.1.
Frequencies to be tested: Mid Range as defined in TS 36.508 [7] clause 4.3.1.1.
Channel Bandwidths to be tested: 10MHz, as defined in TS 36.508 [7] clause 4.3.1.1.
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 9.12.2.2.3-1.
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.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 9.12.2.2.4.3.
9.12.2.2.4.2 Test procedure
1. Set the parameters of bandwidth, the propagation condition, antenna configuration and measurement channel according to Table 9.12.2.2.5-2 as appropriate.
2. The SS shall transmit slot-PDSCH via SPDCCH DCI format 7-1F for C_RNTI to transmit the DL RMC according to CQI value 8 and keep it regardless of the wideband CQI value sent by the UE. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via SPDCCH DCI format 7-0A with CQI request bit set to 1 to schedule UL RMC every 5 ms. Continue transmission of the slot-PDSCH until 2000 wideband CQI reports have been gathered. 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 reports.
3. Set up a relative frequency distribution for the reported wideband CQI-values, reported. Calculate the median value (wideband Median CQI is the wideband CQI that is at or crosses 50% distribution from the lower wideband CQI side). This CQI-value is declared as wideband Median CQI value.
4. If less than (100-)/100*2000 of the wideband CQI values are in the range (Median CQI – 1) ≤ Median CQI ≤ ( Median CQI + 1) then continue with step 5, otherwise go to step 7.
5. The SS shall transmit slot-PDSCH via SPDCCH DCI format 7-1F for C_RNTI to transmit the DL RMC according to the wideband median-CQI value regardless of UE wideband CQI report. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via SPDCCH DCI format 7-0A with CQI request bit set to 1 to schedule UL RMC in every 5 ms. Measure the average throughput according to Annex G.5.3. Declare the throughput as .
6. The SS shall transmit slot-PDSCH via SPDCCH DCI format 7-1F for C_RNTI to transmit the DL RMC according to the wideband CQI value reported from UE. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via SPDCCH DCI format 7-0A with CQI request bit set to 1 to schedule UL RMC every 5 ms. Measure the average throughput according to Annex G.5.3. Declare the throughput as . For any slot-PDSCH transmitted by the SS, record the associated ACK, NACK and statDTX responses. The responses are then filtered as follows: for the sequence of responses for each HARQ process, discard all the statDTX responses. If the ratio (
/
) ≥ and ratio (NACK /(ACK + NACK)) is greater or equal to 0.02, then pass the UE for this test and go to step 8. Otherwise go to step 7.
7. If both SNR points of the test have not been tested, then repeat the same procedure (steps 1 to 6) for the other SNR point as appropriate. Otherwise fail the UE.
8. If both tests have not been done, repeat the same procedure (steps 1 to 7) with test conditions according to the Table 9.12.2.2.3-1 for the other test as appropriate.
