Method and device for supporting vehicle communication in wireless communication system

A user equipment (UE) in a wireless communication system, the UE comprising:

• a transceiver;
• and
• at least one processor coupled with the transceiver and configured to:
• identify that system information including sidelink common configuration is provided by a primary cell;
• generate a message for indicating sidelink UE information;
• and
• transmit, to a base station via the transceiver, the message for indicating the sidelink UE information,
• wherein the at least one processor is further configured to:
• in case that a transmission resource for a sidelink communication is needed, include first information in the message for indicating the sidelink UE information, wherein the first information is associated with a first destination for which the transmission resource for the sidelink communication is requested;
• and
• in case that a sidelink radio link failure (RLF) is declared, include second information in the message for indicating the sidelink UE information, wherein the second information is associated with a second destination for which a sidelink communication failure is reported,
• wherein the first information includes a first destination identity configured by an upper layer for the first destination and a cast type of the first destination identity, and
• wherein the second information includes a second destination identity configured by the upper layer for the second destination and a sidelink failure cause for the second destination.

A method performed by a base station in a wireless communication system, the method comprising:

• receiving, from a user equipment (UE), a message for indicating sidelink UE information,
• wherein the message for indicating the sidelink UE information is associated with system information including sidelink common configuration provided by a primary cell,
• wherein the message for indicating the sidelink UE information includes first information associated with a first destination for which a transmission resource for a sidelink communication is requested, in case that the transmission resource for the sidelink communication is needed,
• wherein the message for indicating the sidelink UE information includes second information associated with a second destination for which a sidelink communication failure is reported, in case that a sidelink radio link failure (RLF) is declared,
• wherein the first information includes a first destination identity configured by an upper layer for the first destination and a cast type of the first destination identity, and
• wherein the second information includes a second destination identity configured by the upper layer for the second destination and a sidelink failure cause for the second destination.
