Method for limiting use of exceptional resource performed by user equipment in wireless communication system and user equipment using method
First Claim
1. A method for performing device-to-device (D2D) operation in a wireless communication system, the method performed by a user equipment (UE) and comprising:
- starting a first timer;
if the first timer is expired;
starting or restarting a second timer, andperforming the D2D operation using an exceptional resource;
determining whether a condition for stopping use of the exceptional resource is satisfied based on the whether the second timer is expired; and
stopping the user of the exceptional resource when performing the D2D operation, based on the determination,wherein the condition for stopping the use is a stop condition in an RRC idle station,wherein, if the second timer is expired, the UE determines that the condition for stopping the use of the exceptional resource is satisfied, andwherein, if the first timer is expired while the second timer is not running, the UE starts the second timer, and if the first timer is expired while the second timer is already running, the UE restarts the second timer.

Abstract
The present invention provides a method for the performance of a device-to-device (D2D) operation by a user equipment (UE) in a wireless communication system, the method comprising the steps of: starting to use an exceptional resource; determining whether a condition for suspending the use of the exceptional resource is satisfied; and when the condition for suspending the use of the exceptional resource is satisfied, suspending the use of the exceptional resource, wherein the condition for suspending the use of the exceptional resource is a suspension condition in an RRC idle state.

11. A user equipment (UE), the UE comprising:
-
a transceiver that transmits and receives a radio signal; and a processor operatively coupled to the transceiver, wherein the processor; starts a first timer; if the first timer is expired; starts or restarts a second timer, and performs device-to-device (D2D) operation using an exceptional resource; determines whether a condition for stopping use of the exceptional resource is satisfied based on whether the second timer is expired; and stops the use of the exceptional resource when performing the (D2D) operation, based on the determination, wherein the condition for stopping the use is a stop condition in an RRC idle state, wherein, if the second timer is expired, the UE determines that the condition for stopping the use of the exceptional resource is satisfied, and wherein, if the first timer is expired while the second timer is not running, the UE starts the second timer, and if the first timer is expired while the second timer is already running, the UE restart the second timer.
