6.3.3D.0 Minimum conformance requirements

When UE is configured for E-UTRA ProSe sidelink transmissions non-concurrent with E-UTRA uplink transmissions for E-UTRA ProSe operating bands specified in Table 5.2D-1, the Prose UE shall meet the Transmit OFF power at all times when the UE is not associated with a serving cell on the ProSe carrier and does not have knowledge of its geographical area or is provisioned with pre-configured radio parameters that are not associated with any known Geographical Area.

The requirements specified in subclause 6.3.3.3 shall apply to UE supporting ProSe when

– the UE is associated with a serving cell on the ProSe carrier, or

– the UE is not associated with a serving cell on the ProSe carrier and is provisioned with the preconfigured radio parameters for ProSe Direct Communications and/or ProSe Direct Discovery that are associated with known Geographical Area, or

– the UE is associated with a serving cell on a carrier different than the ProSe carrier, and the radio parameters for ProSe Direct Discovery on the ProSe carrier are provided by the serving cell, or

– the UE is associated with a serving cell on a carrier different than the ProSe carrier, and has a non-serving cell selected on the ProSe carrier that supports ProSe Direct Discovery and/or ProSe Direct Communication.

When UE is configured for simultaneous E-UTRA ProSe sidelink and E-UTRA uplink transmissions for inter-band E-UTRA ProSe / E-UTRA bands specified in Table 5.2D-2, transmit OFF power is defined as the mean power per component carrier when the transmitter is OFF on all component carriers. During measurement gaps and transmission/reception gaps for ProSe, the UE is not considered to be OFF. Transmit OFF power requirement as specified in subclause 6.3.3.3 apply per carrier.

The normative reference for this requirement is TS 36.101 [2] clause 6.3.3D.

6.3.3D.1 UE Transmit OFF power 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.

– It is not yet clear how many test scenarios are required to cover the set of requirements

– The Test description may be replaced by a reference to the General ON/OFF time mask for ProSe Direct Discovery Test Case

– Message exceptions content

– Test procedure for concurrent operation with E-UTRA uplink transmissions is not defined.

– The Downlink configuration is likely to require discontinuous transmission

6.3.3D.1.1 Test purpose

To verify that the UE transmit OFF power is lower than the value specified in the test requirement.

6.3.3D.1.2 Test applicability

This test case applies to all types of E-UTRA UE release 12 and forward which supports ProSe Direct Discovery.

6.3.3D.1.3 Minimum Conformance requirements

The minimum conformance requirements are defined in clause 6.3.3D.0.

An excess transmit OFF power potentially increases the Rise over Thermal (RoT) and therefore reduces the cell coverage area for other UEs

6.3.3D.1.4.1 Initial condition

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 operating bands specified in table 5.4.2.1-1. All of these configurations shall be tested with applicable test parameters for each channel bandwidth, and are shown in table 6.3.3D.1.4.1-1. The details of the uplink reference measurement channels (RMCs) are specified in Annex A.2, and details of the sidelink reference measurement channels are specified in Annex A.6. Configurations of PDSCH and PDCCH before measurement are specified in Annex C.2.

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 DL Reference Measurement channels are set according to Table 6.3.3D.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 content exception is defined in clause 6.3.3D.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 closed and UE is set to announce discovery.

6.3.3D.1.4.2 Test procedure

1. [The method to configure the UE is FFS].

2. The SS configures the UE with an UL assignment such that the UE transmits [Physical Channel FFS, from the set {PSDCH, PSCCH, PSSCH, PSSS, SSSS, PSBCH}] on the ProSe carrier, on UL sub-frame [FFS] of every radio frame.

3. For FDD: Measure the UE transmission OFF power during the sub-frame prior to the [Physical Channel FFS] subframe. For TDD: Measure the UE transmission OFF power during the 10 SCFDMA symbols prior to the [Physical Channel FFS] subframe.

4. Measure the output power of the UE [Physical Channel FFS] transmission during one sub-frame, excluding a transient period of 20 µs at the beginning of the subframe.

5. Measure the UE transmission OFF power during one sub-frame following the [Physical Channel FFS] subframe, excluding a transient period of 20 µs at the beginning of the subframe.
