Method for performing D2D communication in wireless communication system and device therefor
First Claim
1. A method for performing device-to-device (D2D) communication in a wireless communication system, the method performed by a User Equipment (UE) and comprising:
- switching to a radio resource control (RRC) connection state via transmission of a service request;
receiving allocation of a resource for the D2D communication;
transmitting a D2D signal using the allocated resource;
receiving a system information block (SIB) after transmitting the D2D signal; and
not performing an RRC recovery-related operation if the SIB includes information related to a resource pool even if RRC connection failure occurs within a predetermined time before tracking area update (TAU) grant or TAU rejection is received.

Abstract
One embodiment of the present invention relates to a method by which a terminal performs device-to-device (D2D) communication in a wireless communication system, the method comprising the steps of: converting into a radio resource control (RRC) connection state through the transmission of a service request; being allocated a resource for the D2D communication; transmitting a D2D signal through the allocated resource; and receiving a system information block (SIB) after transmitting the D2D signal, wherein if the SIB includes information on a resource pool, the terminal does not perform an RRC recovery-related operation even if RRC connection failure occurs.
