7.6.2D.0 Minimum conformance requirements

The throughput shall be ≥ 95% of the maximum throughput of the reference measurement channels as specified in Annex A.6.2 with parameters specified in Tables 7.6.2.1D.0-1, 7.6.2.1D.0-2 and 7.6.2.1D.0-3.

7.6.2D.1 Out-of-band blocking 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.

7.6.2D.1.1 Test Purpose

Out-of-band blocking for ProSe is defined for an unwanted CW interfering signal falling more than 15 MHz below or above the ProSe band, at which a given average throughput shall meet or exceed the requirement for the specified measurement channels in aggregated signals.

For the first 15 MHz below or above the ProSe band the appropriate in-band blocking or adjacent channel selectivity in sub-clause 7.5D and sub-clause 7.6.1D shall be applied.

The lack of out-of-band blocking ability will decrease the coverage area when other e-NodeB transmitters exist (except in the adjacent channels and spurious response).

7.6.2D.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.

7.6.2D.1.3 Minimum Conformance Requirements

The minimum conformance requirements are defined in clause 7.6.2D.0.

7.6.2D.1.4 Test Description

7.6.2D.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 7.6.2D.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.

15MHz	QPSK	25	QPSK	25	QPSK	2
20MHz	QPSK	30	QPSK	30	QPSK	2
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.71

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 7.6.2D.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 7.6.2D.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.

7.6.2D.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 7.6.2D.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 7.3D.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 7.6.2D.1.4.1-1. When the UE has no payload data to send, it transmits uplink MAC padding bits on the UL RMC.

6. Set the parameters of the CW signal generator for an interfering signal below the Sidelink Band according to Table 7.6.2D.1.5-2. The frequency step size is 1MHz.

7. SS transmits PSDCH to transmit the SL RMC according to Table 7.6.2D.1.4.1-1. Set the Sidelink signal level to the appropriate value defined in Table 7.6.2D.1.5-1.

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. Record the frequencies for which the throughput doesn’t meet the requirements.

13. Repeat steps from 6 to 12, using an interfering signal above the Sidelink Band at step 6.
