Abstract

Provided is a method for a device-to-device (D2D) action carried out by a terminal in a wireless communication system, the method comprising the steps of: determining priorities for a first D2D action and a second D2D action; on the basis of the determined priorities, determining the D2D action to be carried out from among the first D2D action and second D2D action; and on the basis of the determined D2D action to be carried out, carrying out any one D2D action from among the first D2D action and second D2D action.

First claim

What is claimed is:

1. A method for performing one of a sidelink discovery or a sidelink communication in a wireless communication system, the method performed by a user equipment (UE) and comprising:
determining a priority for the sidelink discovery and a priority for the sidelink communication when the sidelink discovery competes with the sidelink communication; and
performing one of the sidelink discovery or the sidelink communication based on the determined priority for the sidelink communication and the priority for the sidelink discovery,
wherein when the sidelink discovery is a sidelink discovery announcement related to a sidelink relay operation, the UE prioritizes the sidelink discovery rather than the sidelink communication and performs the sidelink discovery.

2. The method of claim 1 , wherein the sidelink communication includes a sidelink communication for a public safety communication or a sidelink communication for a data communication.

3. The method of claim 1 , wherein
the sidelink communication is an operation for communicating between the UE and another UE.

4. The method of claim 1 , wherein the sidelink discovery is an operation for discovering another UE by the UE.

5. A user equipment comprising:
a transceiver configured to transmit and receive signals; and
a processor connected to the transceiver to operate,
wherein the processor is configured to:
determine a priority for a sidelink discovery and a priority for a sidelink communication when the sidelink discovery competes with the sidelink communication; and
perform one of the sidelink discovery or the sidelink communication based on the determined priority for the sidelink communication and the priority for the sidelink discovery,
wherein when the sidelink discovery is a sidelink discovery announcement related to a sidelink relay operation, the UE prioritizes the sidelink discovery rather than the sidelink communication and performs the sidelink discovery.
