Method and apparatus for performing user equipment capability procedure for supporting vehicle communication in next generation mobile communication system

A method performed by a second user equipment (UE) in a radio communication system, the method comprising:

• receiving, from a first UE, a UECapabilityEnquirySidelink message requesting for a sidelink UE capability of the second UE, wherein the UECapabilityEnquirySidelink message includes information associated with a sidelink UE capability including a radio access capability of the first UE and information to request a filtered sidelink UE capability of the second UE;
• transmitting, to the first UE, a message including information associated with the filtered sidelink UE capability of the second UE, in response to reception of the UECapabilityEnquirySidelink message;
• and
• receiving a radio resource control (RRC) message including at least one of information related to a sidelink signaling radio bearer (SRB), information related to a sidelink data radio bearer (DRB), or resource pool, based on the transmitted information associated with the filtered sidelink UE capability of the second UE.

A first user equipment (UE) comprising:

• a transceiver;
• and
• at least one processor configured to:
• control the transceiver to transmit, to a second UE, a UECapabilityEnquirySidelink message requesting fora sidelink UE capability of the second UE, wherein the UECapabilityEnquirySidelink message includes information associated with a sidelink UE capability including a radio access capability of the first UE and information to request a filtered sidelink UE capability of the second UE,
• control the transceiver to receive, from the second UE, a message including information associated with the filtered sidelink UE capability of the second UE, in response to transmission of the UECapabilityEnquirySidelink message, and
• control the transceiver to transmit a radio resource control (RRC) message including at least one of information related to a sidelink signaling radio bearer (SRB), information related to a sidelink data radio bearer (DRB), or resource pool, based on the received information associated with the filtered sidelink UE capability of the second UE.
