7.5G Adjacent Channel Selectivity (ACS) for V2X Communication
36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
7.5G.1 Adjacent channel selectivity (ACS) for V2X Communication / Non-concurrent with E-UTRA uplink transmissions
7.5G.1.1 Test Purpose
Adjacent channel selectivity tests the UE’s ability to receive data with a given average throughput for a specified reference measurement channel, in the presence of an adjacent channel signal at a given frequency offset from the centre frequency of the assigned channel, under conditions of ideal propagation and no added noise.
A UE unable to meet the throughput requirement under these conditions will decrease the coverage area when other e-NodeB transmitters exist in the adjacent channel.
7.5G.1.2 Test Applicability
This test applies to all types of UE that support V2X Sidelink Communication and Band 47.
7.5G.1.3 Minimum Conformance Requirements
The V2X UE shall fulfil the minimum requirement specified in Table 7.5G.1.3-1 for all values of an adjacent channel interferer up to -25 dBm. However it is not possible to directly measure the ACS, instead the lower and upper range of test parameters are chosen in Table 7.5G.1.3-2 and Table 7.5G.1.3-3 where the throughput shall be ≥ 95% of the maximum throughput of the reference measurement channels as specified in Annex A.8.2.

Note 1: V2X con-current band configurations are checked separately for each band configuration, which applicable aggregated channel bandwidths are specified in Table 5.4.2G.1-2. Note 2: Depending on E-UTRA band, only the appropriate Uplink RB allocation value according to table 7.3G.0-4 is tested per Test Channel Bandwidth. The allocation shall be located as close as possible to the downlink operating band but confined within the transmission bandwidth configuration for the channel bandwidth (Table 5.4.2G.1-2). |

1. Connect the SS to the UE antenna connectors as shown in TS 36.508 [7] Annex A, Figure A.93c.
2. The parameter settings for the cell are set up according to TS 36.508 [7] subclause 4.4.3. Message content exceptions are defined in clause 7.5G.2.4.3.
3. Downlink signals are initially set up according to Annex C.0, C.1, and C.3.0, and uplink signals according to Annex H.1 and H.3.0.
4. The UL and V2X Reference Measurement Channels are set according to Table 7.5G.2.4.1-1.
5. Propagation conditions are set according to Annex B.0.
6. Ensure the UE is in State 3A-RF-V2X according to TS 36.508 [7] clause 5.2A.2C. Message content exceptions are defined in clause 7.5G.2.4.3.
7.5G.2.4.2 Test Procedure
1. The SS transmits PDSCH via PDCCH DCI format 1A for C_RNTI to transmit the DL RMC according to Tables 7.5G.2.4.1-1 on E-UTRA Band. The SS sends downlink MAC padding bits on the DL RMC.
2. SS simultaneously sends uplink scheduling information for each UL HARQ process via PDCCH DCI format 0 for C_RNTI to schedule the UL RMC and V2X scheduling information via PDCCH DCI format 5A for SL_V_RNTI to schedule the V2X RMC according to Table 7.5G.2.4.1-1. Since the UE has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL and V2X RMCs.
3. Set the Downlink signal level for V2X band and E-UTRA band to the value as defined in Table 7.5G.2.5-2 (Case 1). Send Uplink power control commands to the UE (less or equal to 1dB step size should be used), to ensure that the UE output power is within +0, – 3.4 dB of the target level in Table 7.5G.2.5-2 (Case 1) for carrier frequency f ≤ 3.0GHz or within +0, -4.0 dB of the target level for carrier frequency 3.0GHz < f ≤ 4.2GHz or within +0, -4.3 dB of the target level for carrier frequency f ≤ 6.0GHz, for at least the duration of the Throughput measurement.
4. Set the Interferer signal level to the value as defined in Table 7.5G.2.5-2 (Case 1) and frequency below and above the wanted signal, using a modulated interferer bandwidth as defined in Annex D of the present document.
5. Measure the mean power of the UE in the channel bandwidth for each test point in table 7.5G.1.5-2 according to the test configuration from Table 7.5G.2.4.1-1. The period of measurement shall be at least continuous duration of one sub-frame (1ms).
6. Set the Downlink signal level for V2X band and E-UTRA band to the value as defined in Table 7.5G.2.5-3 (Case 2). Send Uplink power control commands to the UE (less or equal to 1dB step size should be used), to ensure that the UE output power is within +0, – 3.4 dB of the target level in Table 7.5G.2.5-2 (Case 1) for carrier frequency f ≤ 3.0GHz or within +0, -4.0 dB of the target level for carrier frequency 3.0GHz < f ≤ 4.2GHz or within +0, -4.3 dB of the target level for carrier frequency f ≤ 6.0GHz, for at least the duration of the Throughput measurement.
7. Set the Interferer signal level to the value as defined in Table 7.5G.2.5-3 (Case 2) and frequency below and above the wanted signal, using a modulated interferer bandwidth as defined in Annex D of the present document.
8. Measure the average throughput for a duration sufficient to achieve statistical significance according to Annex G.2.

The initial test configurations consist of environmental conditions, test frequencies, and channel bandwidths based on E-UTRA operating bands specified in Table 5.4.2G.1-2. All of these configurations shall be tested with applicable test parameters for each channel bandwidth, and are shown in table 7.5G.3.4.1-1. The details of the uplink, downlink and V2X reference measurement channels (RMCs) are specified in Annexes A.2, A.3 and A.8.3 respectively and the GNSS configuration in TS 36.508 [7] subclause 4.11.

1. Connect the SS and GNSS simulator to the UE antenna connector as shown in TS 36.508 [7] Annex A, Figure A.92d.
2. The parameter settings for the V2X sidelink communication over PC5 are pre-configured according to TS 36.508 [7] subclause 4.10.1. Message content exceptions are defined in clause 7.5G.3.4.3.
3. Downlink signals are initially set up according to Annex C.0, C.1, and C.3.0, and uplink signals according to Annex H.1 and H.3.0.
4. The UL and V2X Reference Measurement Channels are set according to Table 7.5G.3.4.1-1.
4a. The GNSS simulator is configured for Scenario #1: static in Geographical area #1, as defined in TS36.508 [7] Table 4.11.2-2. Geographical area #1 is also pre-configured in the UE.
5. Propagation conditions are set according to Annex B.0.
6. Ensure the UE is in State 5A-V2X according to TS 36.508 [7] clause 4.5.9.
7. Trigger the UE to reset UTC time. (NOTE: The UTC time reset may be performed by MMI or AT command (+CUTCR).)
8. The GNSS simulator is triggered to start step 1 of Scenario #1 to simulate a location in the centre of Geographical area #1. Wait for the UE to acquire the GNSS signal and start to transmit.
7.5G.3.4.2 Test Procedure
1. The UE starts to perform the V2X sidelink communication according to SL-V2X-Preconfiguration and to schedule the V2X RMC according to Table 7.5G.3.4.1-1.
2. Set the Interferer signal level to the value as defined in Table 7.5G.3.5-2 (Case 1) and frequency below and above the wanted signal, using a modulated interferer bandwidth as defined in Annex D of the present document.
3. Set the Interferer signal level to the value as defined in Table 7.5G.3.5-3 (Case 2) and frequency below and above the wanted signal, using a modulated interferer bandwidth as defined in Annex D of the present document.
4. Measure the average throughput for a duration sufficient to achieve statistical significance according to Annex G.2 .
7.5G.3.4.3 Message Contents
Message contents are according to TS 36.508 [7] subclause 4.6.
7.5G.3.5 Test Requirement
The throughput shall be ≥ 95% of the maximum throughput of the reference measurement channels as specified in Annex A.8.2 with parameters specified in Table 7.5G.3.5-2, and also under the conditions specified in table 7.5G.3.5-3.
