Note 1: Transport block size under test according to applicable Fixed Reference Channel for sustained data-rate test in annex A.3.9. In case of varying TBS across SFs of the RMC, only the maximum TBS is used for PDCP SDU size calculation. Note 2: Each PDCP SDU is limited to 1500 octets (to keep below maximum SDU size of ESM as specified in TS 24.301 clause 9.9.4.12). The PDCP SDU size of each PDCP SDU is: PDCP SDU size = (TBsize – N*PDCP header size – AMD PDU header size – MAC header size – Size of RLC STATUS PDU) / N, where PDCP header size is 16 bits for the RLC AM and 12-bit SN case; AMD PDU header size is CEIL[(16+(N-1)*12)/8] bytes which includes 16 bit standard AM header and (N-1) Length indicators; and MAC header size = R/R/E/LCID/F/L MAC subheader (24 bits for MAC SDU for RLC STATUS PDU with 15 bit LI) + R/R/E/LCID MAC subheader (8 bits for MAC SDU for RLC Data PDU) = 32 bits. The size of RLC STATUS PDU including one ACK_SN field and one NACK_SN field is 32 bits (if no STATUS PDU is sent or if the size of the STATUS PDU is less than 32 bits then padding will be used to fill the 32 bits). This gives: PDCP SDU size = 8*FLOOR((TBsize – N*16- 8*CEIL((16+(N-1)*12)/8) – 64)/(8*N)) bits. The calculation of PDCP SDU sizes does not consider timing advance MAC CE as timing advance is not transmitted by SS for RF test cases, and the header sizes are informative and may vary during the test. Note 3: 35160 bits for sub-frame 5 Note 4: 71112 bits for sub-frame 5 |
||||||
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.
Resource pool configuration for PSCCH and PSSCH reference measurement channels are set according to Table 14.9.3-1 and Annex A.9 as appropriate.
Test Environment: Normal, as defined in TS 36.508 [7] clause 4.1.
Frequencies to be tested: Mid Range for E-UTRA channel and Mid Range for V2X channel, as defined in TS 36.508 [7] clause 4.3.1.2 (for operating band 47 use clause 4.3.1.2.15).0
Channel Bandwidths to be tested: As specified per test number in Table 14.9.3-2 as defined in TS 36.508 [7] clause 4.3.1.2 (for operating band 47 use clause 4.3.1.2.15).
1. Connect the SS to the UE antenna connectors, connect the SS COM port to the UE COM port as shown in TS 36.508 [7] Annex A, Figure TBD.
2. The parameter settings for the cell and V2X sidelink transmission over PC5 interface are set up according to Table 14.9.3-1, Table 14.9.3-2 and Table 14.9.3-3. Message content exceptions are defined in clause 14.9.4.3.
3. E-UTRA 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. Sidelink physical channels and signals are initially set up according to Table 14.9.3-1 and Annex A.9 as appropriate.
5. Propagation conditions are set according to Annex B.0.
6. Ensure the UE is in State 3A-RF-V2X in Receive Mode according to TS 36.508 [7] clause 5.2A.2C. Message contents are defined in clause 14.9.4.3.
14.9.4.2 Test procedure
1. Propagation conditions are set according to Annex B.1 (No external noise sources are applied).
On E-UTRA carrier:
2. The SS looks up TBsize in Table 14.9.4.1-1 for the tests to be performed depending on the UE category according to Table 14.9.5-4.
3. SS sets the counters NDL_newtx, NDL_retx, NUL_PDCP, and NDL_PDCP to 0.
4. For each new DL HARQ transmission the SS generates sufficient PDCP SDUs to fill up the TB in accordance with Table 14.9.4.1-1 (Note 1). The SS ciphers the PDCP SDUs, concatenates the resultant PDCP PDUs to form an RLC PDU and then a MAC PDU. The SS transmits the MAC PDU. The SS increments then NDL_newtx by one and NDL_PDCP by the number of new PDCP SDUs (Note 1) included in the sent MAC PDU.
5. If PHY requests a DL HARQ retransmission, the SS performs a HARQ retransmission and increments NDL_retx by one.
6. Steps 4 to 5 are repeated at every TTI for at least 300 frames and the SS waits for 300ms to let any HARQ retransmissions and RLC retransmissions to finish.
7. For each PDCP SDU received at the SS, if the content of the data matches that of the truncated version of the original PDCP SDU generated at the SS, the SS increments NUL_PDCP by one.
8. The SS calculates the TB success rate as A = 100%*NDL_newtx/ (NDL_newtx + NDL_retx). Measurements are not based on UE feedback but on SS counters instead (NDL_newtx and NDL_retx) in order to validate HARQ feedback received from the UE.
9. The SS calculates the PDCP SDU loss as B = NDL_PDCP – NUL_PDCP
10. The UE passes the E-UTRA subtest if A ≥ "corresponding TB success rates according to Table 8.7.1.1.5-1" and B = 0.
On Sidelink carrier:
11. Sidelink UE0 ~ UE14 transmit PSSCH one by one circularly via PSCCH SCI format 1 for SL-V-RNTI, according to SL-V2X-Preconfiguration, to transmit their respective sidelink RMC according to Table 14.7.3-2. All sidelink UEs transmit MAC padding bits on their respective sidelink RMC.
12. Set the parameters of the bandwidth, MCS, reference channel, the propagation condition, the correlation matrix and the SNR for each sidelink UE according to Tables 14.9.3-1 and 14.9.5-1 as appropriate.
13. Measure the average PSSCH BLER of all the sidelink UEs for a duration sufficient to achieve statistical significance according to Annex G clause G.8. In order to measure the PSSCH BLER, the SS shall request the UE to report the counter of successful reception of sidelink UE PSSCH transmissions using AT commands as specified in Annex G clause G.8.2 and 36.508 [7] clause 4.7I. The PSSCH BLER of sidelink UEs is calculated as specified in Annex G clause G.8.2. If the measured average PSSCH BLER of sidelink UEs is less than the reference value in Table 14.9.5-1, the UE passes the Sidelink subtest. Otherwise the UE fails the Sidelink subtest.
14. If the UE passes the E-UTRA subtest in step 10, and passes the Sidelink subtest in step 13, pass the UE. Otherwise fail the UE.
NOTE 1: In case of RLC PDU retransmission, the number of new required PDCP SDUs is as many as to fill the rest of TB.
