Abstract
Provided are a method by which a base station performs vehicle to everything (V2X) communication in a wireless communication system, and an apparatus for supporting the same. The method can comprise the steps of: receiving a V2X bearer indication indicating a V2X bearer, wherein the V2X bearer is a bearer used for a V2X service; determining that the base station supports only a PC5-based V2X service between the PC5-based V2X service or a Uu-based V2X service; postponing a resource allocation for the V2X bearer; and transmitting, to a mobility management entity (MME), information indicating that the resource allocation for the V2X bearer is postponed.
Claims2
A method for performing vehicle to everything (V2X) communication by a user equipment (UE) in a wireless communication system, comprising:
- receiving information indicating a postponement of resource allocation for a V2X bearer from a base station, wherein the V2X bearer is a bearer being used for V2X service;
- based on receiving the information, postponing a deactivation of the V2X bearer and maintaining a context of the V2X bearer,
- wherein, the resource allocation for the V2X bearer is postponed by the base station, based on the base station which supports only PC5-based V2X service, among PC5-based V2X service and Uu-based V2X service;
- while postposting the deactivation of the V2X bearer:
- receiving a radio resource control (RRC) connection reconfiguration message from the base station;
- and
- based on receiving the RRC connection reconfiguration message, determining not to postpone the deactivation of the V2X bearer.
