8.12.2.1.1.4 Test description
8.12.2.1.1.4.1 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 NPDSCH and NPDCCH before measurement are specified in C.2.
Test Environment: Normal, as defined in TS 36.508 [7] clause 4.1.
Operation mode: Standalone.
Frequencies to be tested: K.2.1.
Channel Bandwidths to be tested: As specified per test number in Table 8.12.2.1.1.3-1.
1. Connect the SS, the faders and AWGN noise sources to the UE antenna connectors as shown in TS 36.508 [7] Annex A, Figure A.9 using only main UE Tx/Rx antenna.
2. The parameter settings for the cell are set up according to Tables 8.12.2.1-1 and 8.12.2.1.1.3-1 as appropriate.
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.0.1, H.1.1, H.2.1 and Annex H.4.2.
4. Propagation conditions are set according to Annex B.0.
5. Ensure the UE is in State 2A-NB with CP CIoT Optimisation according to TS 36.508 [7] clause 8.1.5. Message contents are defined in clause 8.12.2.1.1.4.3.
8.12.2.1.1.4.2 Test procedure
1. SS transmits NPDSCH via NPDCCH DCI format N1 for C_RNTI to transmit the DL RMC according to Tables 8.12.2.1-1, 8.12.2.1-2 and 8.12.2.1.1.3-1. The details of NPDCCH are specified in Table A.3.13.1. The SS sends downlink MAC padding bits on the DL RMC.
2. Set the parameters of the bandwidth, MCS, reference channel, the propagation condition and the SNR according to Tables 8.12.2.1.1.5-1 as appropriate.
3. Measure the Pm-dsg for a duration sufficient to achieve statistical significance according to Annex G clause G.4. Count the number of NACKs, ACKs and statDTXs on the UL NPUSCH during each subtest. Pm-dsg is the radio (statDTX)/(NACK +ACK+statDTX). If Pm-dsg is less than the value specified in table 8.12.2.1.1.5-1, UE pass the subtest. Otherwise fail the UE.
4. SS release the connection through State 3A-NB and finally ensure the UE is in State 2A-NB with CP CIoT Optimisation according to TS 36.508 [7] clause 8.1.5. Configure the Non-anchor carrier according to table 8.12.2.1.1.4.3-1.
5. Repeat steps from 1 to 3 for subtest 2 in Table 8.12.2.1.1.5-1 as appropriate.
