NOTE 1: For certain bands, the unwanted modulated interfering signal may not fall inside the UE receive band, but within the first 15 MHz below or above the UE receive band. NOTE 2: For each carrier frequency the requirement is valid for two frequencies: a. the carrier frequency -BW/2 – F_{Ioffset, case 1}and b. the carrier frequency +BW/2 + F_{Ioffset, case 1} NOTE 3: F_Interferer range values for unwanted modulated interfering signal are interferer centre frequencies.

For the UE which supports inter band CA configuration in Tables 7.3.3-1A, 7.3.3-1B and 7.3.3-1C, P_Interferer power defined in Tables 7.6.1D.0-3 is increased by the amount given by ΔR_IB,c in Table 7.3.3-1A, 7.3.3-1B and 7.3.3-1C.

The normative reference for this requirement is TS 36.101 [2] clause 7.6.1.1D.

7.6.1D.1 In-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.

7.6.1D.1.1 Test Purpose

In-band blocking is defined for an unwanted interfering signal falling into the range from 15MHz below to 15MHz above the ProSe band, at which the relative throughput shall meet or exceed the requirement for the specified measurement channels.

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

7.6.1D.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.

7.6.1D.1.3 Minimum Conformance Requirements

The minimum conformance requirements are defined in clause 7.6.1D.0.

7.6.1D.1.4 Test Description

7.6.1D.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 7.6.1D.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.

Initial Conditions
Test Environment as specified in TS 36.508[7] subclause 4.1			NC
Test Frequencies as specified in TS36.508 [7] subclause 4.3.1			Mid range(Note 4)
Test Channel Bandwidths as specified in TS 36.508 [7] subclause 4.3.1			5MHz, Highest

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.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 7.6.1D.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 7.6.1D.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.

7.6.1D.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 7.6.1D.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 7.3D.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 7.6.1D.1.4.1-1. Set the Sidelink signal level to the appropriate value defined in Table 7.6.1D.1.5-1.

7. Set the parameters of the signal generator for an interfering signal below the aggregated component carriers in Case 1 according to Tables 7.6.1D.1.5-1 and 7.6.1D.1.5-2.

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.

10. 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".

11. SS calculates the variable Pok as (current counter value – counter value at last test iteration).

12. SS shall compute the throughput as following:

TP = Pok / Ptot * 100%

13. Repeat steps from 6 to 12, using an interfering signal above the wanted signal in Case 1 at step 7.

14. Repeat steps from 6 to 13, using interfering signals in Case 2 at step 7 and 13. The ranges of case 2 are covered in steps equal to the interferer bandwidth. The test frequencies are chosen in analogy to table 7.6.1D.1.4.2-1.
