Claims (15)

A wireless communication user equipment (UE),
memory;
a transceiver;
a processor coupled to the memory and the transceiver;
The processor
controlling the transceiver to receive sidelink resource configuration signaling for one or more radio access technologies (RATs) from a base station; A wireless communication user equipment (UE) configured to control to report a 2. The user equipment of claim 1, wherein the processor is configured to control the transceiver to receive from the base station a query request related to UE capabilities of a UE. 3. A user equipment according to claim 1 or 2, wherein said sidelink resource configuration signaling is sent using different system information blocks for different RATs. The UE capabilities include at least one of UE cross-RAT capabilities and inter-UE RAT capabilities, and the UE cross-RAT capabilities are any of New Radio (NR) RAT and Long Term Evolution (LTE) RAT. configured to use one or both for sidelink V2X communication, wherein said UE inter-RAT capability is configured to perform processing and signaling exchanges between NR RAT and LTE RAT. A user equipment according to any one of the preceding claims. The UE cross-RAT capability configured to use one or both of the NR RAT and the LTE RAT for sidelink V2X communication indicates that the transceiver tells the base station that the UE for each RAT 5. The user equipment of claim 4 , performed by reporting a list of frequency bands and frequency band combinations supported by the UE along with the features it supports. If the list of frequency bands and frequency band combinations supported by the UE together with features supported by the UE includes frequency bands dedicated to vehicle-to-everything (V2X) operation for one RAT, the UE may 6. The user equipment of claim 5 , supporting V2X communication. The UE inter-RAT capability is the minimum or 5. The user equipment of claim 4, comprising a maximum duration/offset measurement. A method of wireless communication for a user equipment, comprising:
Radio communication of user equipment comprising receiving sidelink resource configuration signaling for one or more radio access technologies (RATs) from a base station and reporting to said base station that UE capabilities support cross-RAT control. the method of. 9. The method of claim 8 , further comprising receiving a query request related to UE capabilities of a UE from the base station. 10. A method according to claim 8 or 9 , wherein the sidelink resource configuration signaling is sent using different system information blocks for different RATs. The UE capabilities include at least one of UE cross-RAT capabilities and inter-UE RAT capabilities, and the UE cross-RAT capabilities are any of New Radio (NR) RAT and Long Term Evolution (LTE) RAT. configured to use one or both for sidelink V2X communication, wherein said UE inter-RAT capability is configured to perform processing and signaling exchanges between NR RAT and LTE RAT . Any method described. An indication that the UE cross-RAT capability configured to use either or both of the NR RAT and the LTE RAT for sidelink V2X communication indicates that the UE is configured to the base station for each RAT. 12. The method of claim 11 , performed by reporting a list of frequency bands and frequency band combinations supported by the UE along with supporting features. If the list of frequency bands and frequency band combinations supported by the UE together with features supported by the UE includes frequency bands dedicated to vehicle-to-everything (V2X) operation for one RAT, the UE 13. The method of claim 12 , supporting link V2X communication. The UE inter-RAT capability is the minimum or 12. The method of claim 11 , comprising measuring maximum duration/offset. A method according to any of claims 8 to 14 , wherein the UE receives a query request related to the UE capabilities from the base station when the UE is in RRC connected state.
