Abstract
A method and apparatus for performing device-to-device (D2D) transmission in a wireless communication system is provided. A user equipment (UE) determines that it is out of coverage (OOC). Even though the UE is OOC, the UE continues to perform D2D transmission by using D2D resources for in-coverage under a specific condition. Based on a specific condition, if the UE determines that is in coverage before the specific condition is met, the UE performs D2D transmission by using the D2D resources for in-coverage. If the specific condition is met while the UE is OOC, the UE performs D2D transmission by using the D2D resources for OOC.
Claims15
A method for performing, by a user equipment (UE), device-to-device (D2D) transmission in a wireless communication system, the method comprising:
- determining, by the UE, that the UE is out of coverage (OOC);
- continuing, by the UE, to perform D2D transmission by using D2D resources for in-coverage under a specific condition;
- and
- performing, by the UE, D2D transmission by using either one of the D2D resources for in-coverage or D2D resources for OOC based on the specific condition.
A user equipment (UE) configured to perform device-to-device (D2D) transmission in a wireless communication system, the UE comprising:
- a radio frequency (RF) unit configured to transmit or receive a radio signal;
- and
- a processor coupled to the RF unit, and configured to:
- determine that the UE is out of coverage (OOC);
- continue to use perform D2D transmission by using D2D resources for in-coverage under a specific condition;
- and
- perform D2D transmission by using either one of the D2D resources for in-coverage or D2D resources for OOC based on the specific condition.
