9.2.5.1 Test purpose

To verify for each subframe set, the variance of the reported CQI value is within the limits defined, the PDSCH BLER of 10% falls between the transport format indicated by median CQI-1 and CQI or the transport format indicated by median CQI and CQI+1, and the difference of the median CQI obtained by reports in CSI subframe sets CCSI,0 and the median CQI obtained by reports in CSI subframe sets CCSI,1 shall be larger than or equal to 3.

9.2.5.2 Test applicability

This test applies to E-UTRA TDD release 12 and forward UEs of Category 2 and onwards which supports eIMTA TDD UL-DL reconfiguration for TDD serving cell(s) via monitoring PDCCH with eIMTA-RNTI and Rel-12 CSI subframe sets.

9.2.5.3 Minimum conformance requirements

The following requirements apply to UE Category ≥2 which supports eIMTA TDD UL-DL reconfiguration for TDD serving cell(s) via monitoring PDCCH with eIMTA-RNTI and Rel-12 CSI subframe sets. For the parameters specified in table 9.2.5.3-1, and using the downlink physical channels specified in Tables C.3.2-1 and C.3.2-2, for each CSI subframe set, the reported CQI value shall be in the range of ±1 of the reported median more than 90% of the time.

Note 4: As specified in Table 4.2-2 in TS 36.211.

Note 5: UL/DL configuration in PDCCH with eIMTA-RNTI is cyclically selected from the given set on a per-DCI basis.

Note 6: To avoid collisions between CQI/PMI reports and HARQ-ACK it is necessary to report both on PUSCH instead of PUCCH. PDCCH DCI format 0 shall be transmitted in downlink SF#1 and #6 to allow periodic CQI/PMI to multiplex with the HARQ-ACK on PUSCH in uplink SF#7 and #2. CQI/PMI reports for CSI subframe set 0 is transmitted in SF#2 and CQI/PMI reports for CSI subframe set 1 is transmitted in SF#7.

Note 7: RI reporting interval is set to the maximum allowable length of 160ms to minimise collisions between RI, CQI/PMI and HARQ-ACK reports. In the case when all three reports collide, it is expected that CQI/PMI reports will be dropped, while RI and HARQ-ACK will be multiplexed. At eNB, CQI report collection shall be skipped every 160ms during performance verification.

The normative reference for this requirement is TS 36.101 [2] clause 9.2.5.

9.2.5.4 Test description

9.2.5.4.1 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 4.3.1.2.

Channel Bandwidths to be tested: 10MHz, as defined in TS 36.508 [7] clause 4.3.1.2

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.10 for UE with 2Rx RF.

2. The parameter settings for the cell are set up according to Table 9.2.5.3-1.

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.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 9.2.5.4.3.

9.2.5.4.2 Test procedure

1. Set the parameters of bandwidth, reference Channel, the propagation condition, antenna configuration and the SNR according to Table 9.2.5.3-1 as appropriate.

2. The SS shall transmit PDSCH via PDCCH DCI format 1A 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 PDCCH DCI format 0 with CQI request bit set to 0 to schedule UL RMC in subframe #2 and subframe #7 (Table A.4.1-2). The UE will send ACK/NACK and periodic CQI report using PUSCH. Continue transmission of the PDSCH until 2000 wideband CQI reports for each CSI subframe sets have been gathered. In this process the SS collects wideband CQI reports for CSI subframe set 0 at every SF#2 and wideband CQI reports for CSI subframe set 1 at every SF#7, and also cases where UE transmits nothing in its CQI timing are counted as wideband CQI reports.

3. For each CSI subframe set, set up a relative frequency distribution for the reported wideband CQI-values. Calculate the median values (wideband Median CQI is the CQI that is at or crosses 50% distribution from the lower wideband CQI side). These CQI-values are declared as wideband Median CQI0 for CSI subframe set 0 and Median CQI1 for CSI subframe set 1.

4. If for both CSI subframe sets, the Median CQIs are not equal to 1 or 15 and 1800 or more of the wideband CQI values are in the range (Median CQI – 1) ≤ Median CQI ≤ ( Median CQI + 1), and the difference between the 2 Median CQIs is larger than or equal to 3, then continue with step 5, otherwise go to step 10.

5. The SS shall transmit PDSCH via PDCCH DCI format 1A for C_RNTI to transmit the DL RMC on CSI subframe set 0 according to the Median CQI0, and on CSI subframe set 1 according to the Median CQI1 and shall not react to the UE’s wideband CQI reports. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via PDCCH DCI format 0 with CQI request bit set to 0 to schedule UL RMC in subframe #2 and subframe #7 (Table A.4.1-2). The UE will send ACK/NACK and periodic CQI report using PUSCH. For any PDSCH transmitted by the SS, record the associated ACK, NACK and statDTX responses for 2 CSI subframe sets respectively. In case statDTX cannot be differentiated from NACK due to multiplexing effect, evaluate the feedback as a NACK. The responses are then filtered as follows: for the sequence of responses for each HARQ process, discard all the statDTX responses. Continue to gather data until the number of filtered ACK+NACK responses for each CSI subframe set reaches 1000.

For the filtered ACK and NACK responses:

if the ratio (NACK / ACK + NACK) in CSI subframe set 0 ≤ 0.1, and the ratio (NACK / ACK + NACK) in CSI subframe set 1 ≤ 0.1, then go to step 6,

if the ratio (NACK / ACK + NACK) in CSI subframe set 0 ≤ 0.1, and the ratio (NACK / ACK + NACK) in CSI subframe set 1 > 0.1, then go to step 7,

if the ratio (NACK / ACK + NACK) in CSI subframe set 0 > 0.1, and the ratio (NACK / ACK + NACK) in CSI subframe set 1 ≤ 0.1, then go to step 8,

if the ratio (NACK / ACK + NACK) in CSI subframe set 0 > 0.1, and the ratio (NACK / ACK + NACK) in CSI subframe set 1 > 0.1, then go to step 9.

6. The SS shall transmit PDSCH via PDCCH DCI format 1A for C_RNTI to transmit the DL RMC on CSI subframe set 0 according to the Median CQI0+1, and on CSI subframe set 1 according to the Median CQI1+1 and shall not react to the UE’s wideband CQI reports. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via PDCCH DCI format 0 with CQI request bit set to 0 to schedule UL RMC in subframe #2 and subframe #7 (Table A.4.1-2). The UE will send ACK/NACK and periodic CQI report using PUSCH. For any PDSCH transmitted by the SS, record and filter the ACK, NACK and statDTX responses as in step 5 until 1000 filtered ACK+NACK responses for each CSI subframe set are gathered. In case statDTX cannot be differentiated from NACK due to multiplexing effect, evaluate the feedback as a NACK

if the ratio (NACK / ACK + NACK) in CSI subframe set 0 > 0.1, and the ratio (NACK / ACK + NACK) in CSI subframe set 1 > 0.1, then pass the UE for this test, otherwise go to step 10.

7. The SS shall transmit PDSCH via PDCCH DCI format 1A for C_RNTI to transmit the DL RMC on CSI subframe set 0 according to the Median CQI0+1, and on CSI subframe set 1 according to the Median CQI1-1 and shall not react to the UE’s wideband CQI reports. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via PDCCH DCI format 0 with CQI request bit set to 0 to schedule UL RMC in subframe #2 and subframe #7 (Table A.4.1-2). The UE will send ACK/NACK and periodic CQI report using PUSCH. For any PDSCH transmitted by the SS, record and filter the ACK, NACK and statDTX responses as in step 5 until 1000 filtered ACK+NACK responses for each CSI subframe set are gathered. In case statDTX cannot be differentiated from NACK due to multiplexing effect, evaluate the feedback as a NACK

if the ratio (NACK / ACK + NACK) in CSI subframe set 0 > 0.1, and the ratio (NACK / ACK + NACK) in CSI subframe set 1 ≤ 0.1, then pass the UE for this test, otherwise go to step 10.

8. The SS shall transmit PDSCH via PDCCH DCI format 1A for C_RNTI to transmit the DL RMC on CSI subframe set 0 according to the Median CQI0-1, and on CSI subframe set 1 according to the Median CQI1+1 and shall not react to the UE’s wideband CQI reports. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via PDCCH DCI format 0 with CQI request bit set to 0 to schedule UL RMC in subframe #2 and subframe #7 (Table A.4.1-2). The UE will send ACK/NACK and periodic CQI report using PUSCH. For any PDSCH transmitted by the SS, record and filter the ACK, NACK and statDTX responses as in step 5 until 1000 filtered ACK+NACK responses for each CSI subframe set are gathered. In case statDTX cannot be differentiated from NACK due to multiplexing effect, evaluate the feedback as a NACK

if the ratio (NACK / ACK + NACK) in CSI subframe set 0 ≤ 0.1, and the ratio (NACK / ACK + NACK) in CSI subframe set 1 > 0.1, then pass the UE for this test, otherwise go to step 10.

9. The SS shall transmit PDSCH via PDCCH DCI format 1A for C_RNTI to transmit the DL RMC on CSI subframe set 0 according to the Median CQI0-1, and on CSI subframe set 1 according to the Median CQI1-1 and shall not react to the UE’s wideband CQI reports. The SS sends downlink MAC padding bits on the DL RMC. The SS sends uplink scheduling information via PDCCH DCI format 0 with CQI request bit set to 0 to schedule UL RMC in subframe #2 and subframe #7 (Table A.4.1-2). The UE will send ACK/NACK and periodic CQI report using PUSCH. For any PDSCH transmitted by the SS, record and filter the ACK, NACK and statDTX responses as in step 5 until 1000 filtered ACK+NACK responses for each CSI subframe set are gathered. In case statDTX cannot be differentiated from NACK due to multiplexing effect, evaluate the feedback as a NACK

if the ratio (NACK / ACK + NACK) in CSI subframe set 0 ≤ 0.1, and the ratio (NACK / ACK + NACK) in CSI subframe set 1 ≤ 0.1, then pass the UE for this test, otherwise go to step 10.

10. If both SNR points of the test have not been tested, then repeat the same procedure (steps 1 to 9) for the other SNR point as appropriate. Otherwise fail the UE.

9.2.5.5 Test requirement

The pass fail decision is as specified in the test procedure in clause 9.2.5.4.2.

There are no parameters in the test setup or measurement process whose variation impacts the results so there are no applicable test tolerances for this test.
