6.3E.0 Minimum conformance requirements

6.3E.0.1 General

The E-UTRA SL and NR SL switching time mask defines the observation period between E-UTRA subframe and NR slot/mini-slot boundary. Both E-UTRA subframe and NR slot/mini-slot have ON power transmissions. The ON power is defined as the mean power over the symbol duration excluding any transient period. For E-UTRA subframe or NR slot/mini-slot having OFF power transmission, the general time mask for E-UTRA or NR shall apply.

6.3E.0.2 Output power dynamics for intra-band V2X operation

For intra-band V2X operation bands specified in subclause 5.3E.1 and 5.3E.2, the SL switching time masks in Figure 6.3E.2-1 shall apply.

The switching time shall be located on the RAT of lower priority when NR SL and LTE SL have different priorities based on priority information specified in TS 38.213. It is up to UE implementation when NR SL and LTE SL have the same priority based on priority information specified in TS 38.213.

6.3E.0.3 Output power dynamics for inter-band V2X con-current operation

For inter-band con-current NR V2X operation, the output power dynamics requirement shall be applied per each component carrier. The output dynamic requirements specified in clause 6.3 of TS 36.101 [5] apply for E-UTRA UL transmission and the requirements specified in clause 6.3E of TS 38.101-1 [2] apply for NR SL transmission. The output dynamic requirements specified in clause 6.3.2G, 6.3.3G, 6.3.4G of TS 36.101 [5] apply for E-UTRA SL transmission and the requirements specified in clause 6.3 of TS 38.101-1 [2] apply for NR UL transmission.

The normative reference for this requirement is TS 38.101-3 [4] clause 6.3E.

6.3E.1 Output power dynamics for intra-band V2X operation

SL switching time mask requirements are specified for intra-band V2X operation, giving criteria on how the switching period position is decided based on priority information. No test is needed for this time mask requirement.

6.3E.2 Output power dynamics for inter-band V2X operation

For inter-band V2X operation, no exception requirements are specified for the E-UTRA/NR Uu carrier and E-UTRA/NR SL carrier.

For inter-band V2X configuration with E-UTRA Uu and NR sidelink, the requirements in this test case can be well covered in clause 6.3.2, 6.3.3, 6.3.4 and 6.3.5 of TS 36.521-1 [10] for E-UTRA Uu carrier and clause 6.3E.1.1, [6.3E.2.2, 6.3E.3.2.1, 6.3E.3.3.1 and 6.3E.3.4.1] of TS 38.521-1 [8] and don’t need to be tested again.

For inter-band V2X configuration with NU Uu and E-UTRA V2X sidelink, the requirements in this test case can be well covered in clause 6.3.1, 6.3.2, 6.3.3 and 6.3.4 of TS 38.521-1 [8] for NR Uu carrier and clause 6.3.2G.1, 6.3.3G.1, 6.3.4G.1 and 6.3.4G.4 of TS 36.521-1 [10] and don’t need to be tested again.
