7.5D.0 Minimum conformance requirements
The UE shall fulfil the minimum requirement specified in Table 7.5D.0-1 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 7.5D.0-2 and Table 7.5D.0-3 where the throughput shall be ≥ 95% of the maximum throughput of the reference measurement channels as specified in Annex A.6.2.

7.5D.1 Adjacent Channel Selectivity (ACS) for ProSe Direct Discovery
Editor’s note: This test case is not complete. Following aspects are either missing or not yet determined:
– ProSe UE authentication is not handled in the test case and is still under investigation.
– Use of OCNG for Downlink has not been considered and is still FFS.
– Message exceptions content needs further investigation (some values still TBD).
– Test time is FFS.
7.5D.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.
7.5D.1.2 Test Applicability
This test applies to all types of E-UTRA UE release 12 and forward which support ProSe Direct Discovery, but not ProSe Direct Communication.
7.5D.1.3 Minimum Conformance Requirements
The minimum conformance requirements are defined in clause 7.5D.0.
7.5D.1.4 Test Description
7.5D.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.
The initial test configurations consist of environmental conditions, test frequencies, and channel bandwidths based on E-UTRA ProSe bands specified in table 5.4.2D.1-1. All of these configurations shall be tested with applicable test parameters for each channel bandwidth, and are shown in table 7.5D.1.4.1-1. The details of the downlink, uplink and sidelink reference measurement channels (RMCs) are specified in Annexes A.2, A.3 and A.6.

Note 1: Test Channel Bandwidths are checked separately for each E-UTRA ProSe and Operating band, according to the applicability specified respectively in Table 5.4.2D.1-1 and Table 5.4.2.1-1. Note 2: After DRX configuration, DL-RMC (PDSCH) and DCI-0 for scheduling UL-RMC (PUSCH) are applied only in the DRX On subframes. Note 3: The RB start for the transmission of Sidelink RMC is RB#0. Note 4: Sidelink uses the frequencies defined for Uplink. |

1. Connect the SS to the UE antenna connectors as shown in TS 36.508 [7] Annex A, Figure A.70.
2. The parameter settings for the cell are set up according to TS 36.508 [7] clause 4.4.3.
3. Downlink signals are initially set up according to Annex C.0, C.1 and C.3.1, and uplink signals according to Annex H.1 and H.3.1.
4. The UL and DL Reference Measurement channels are set according to Table 7.5D.1.4.1-1.
5. Propagation conditions are set according to Annex B.0.
6. Ensure the UE is in State 2A-RF according to TS 36.508 [7] clause 5.2A.1A. Message contents exceptions are defined in clause 7.5D.1.4.3.
7. SS continues with the generic procedures described in TS 36.508 [7] clause 4.5.3A.3 and 4.5.4.3 and ensures the UE is in State 4 according to TS 36.508 [7] clause 4.5.4 and the UE test loop Mode D is activated.
7.5D.1.4.2 Test Procedure
1. SS shall transmit an RRCConnectionReconfiguration message to configure DRX. Message contents exceptions (only those marked with "…Step 1…") are defined in clause 7.5D.1.4.3.
2. The UE shall transmit RRCConnectionReconfigurationComplete message.
3. Initialise the variables Ptot and Pok as 0.
4. SS transmits PDSCH via PDCCH DCI format 1A for C_RNTI to transmit the DL RMC according to Table 7.5D.1.4.1-1. The SS sends downlink MAC padding bits on the DL RMC.
5. SS sends uplink scheduling information via PDCCH DCI format 0 for C_RNTI to schedule the UL RMC according to Table 7.5D.1.4.1-1. When the UE has no payload data to send, it transmits uplink MAC padding bits on the UL RMC.
6. SS transmits PSDCH to transmit the SL RMC according to Table 7.5D.1.4.1-1. Set the Sidelink signal level to the appropriate value defined in Table 7.5D.1.4.1-1 to the value as defined in Table 7.5D.1.5-2 (Case 1)
7. Set the Interferer signal level to the value as defined in Table 7.5D.1.5-2 (Case 1) and frequency below the wanted signal, using a modulated interferer bandwidth as defined in Annex D of the present document.
8. SS shall send SL Discovery Packets (MAC padding bits) on the SL RMC for the test time [FFS]. SS stores the number of the transmitted Discovery Packets in the current test iteration in the variable Ptot.
9. SS shall send (on the available PDSCH) a "UE TEST LOOP PROSE MODE D SIDELINK DIRECT DISCOVERY PACKET COUNTER REQUEST" message and wait for the UE to respond (on the available PUSCH) with a "UE TEST LOOP PROSE MODE D SIDELINK DIRECT DISCOVERY PACKET COUNTER RESPONSE".
10. SS calculates the variable Pok as (current counter value – counter value at last test iteration).
11. SS shall compute the throughput as following:
TP = Pok / Ptot * 100%
12. Repeat steps from 6 to 12, using an interfering signal above the wanted signal in Case 1 at step 7.
13. SS transmits PSDCH to transmit the SL RMC according to Table 7.5D.1.4.1-1. Set the Sidelink signal level to the appropriate value defined in Table 7.5D.1.4.1-1 to the value as defined in Table 7.5D.1.5-3 (Case 2)
14. Set the Interferer signal level to the value as defined in Table 7.5D.1.5-3 (Case 2) and frequency below the wanted signal, using a modulated interferer bandwidth as defined in Annex D of the present document.
15. SS shall send SL Discovery Packets (MAC padding bits) on the SL RMC for the test time [FFS]. SS stores the number of the transmitted Discovery Packets in the current test iteration in the variable Ptot.
16. SS shall send (on the available PDSCH) a "UE TEST LOOP PROSE MODE D SIDELINK DIRECT DISCOVERY PACKET COUNTER REQUEST" message and wait for the UE to respond (on the available PUSCH) with a "UE TEST LOOP PROSE MODE D SIDELINK DIRECT DISCOVERY PACKET COUNTER RESPONSE".
17. SS calculates the variable Pok as (current counter value – counter value at last test iteration).
18. SS shall compute the throughput as following:
TP = Pok / Ptot * 100%
19. Repeat steps from 13 to 18, using an interfering signal above the wanted signal in Case 2 at step 14.
