Abstract
A method and apparatus for transmitting information on out-of-coverage (OOC) for a device-to-device (D2D) operation in a wireless communication system is provided. A user equipment (UE) determines that the UE is OOC. OOC may be determined to at least one of a normal OOC or an early OOC based on criteria. Then, the UE transmits information indicating that the UE is OOC to other UEs.
Claims15
A method for transmitting, by a user equipment, information on out-of-coverage (OOC) for a device-to-device (D2D) operation in a wireless communication system, the method comprising:
- determining, by the UE, that the UE is out of coverage;
- and
- transmitting, by the UE, information indicating that the UE is out of coverage to other UEs.
A method for transmitting, by a user equipment, a synchronization signal for device-to-device (D2D) operation in a wireless communication system, the method comprising:
- determining, by the UE, whether the UE is out of coverage or not;
- and
- if it is determined that the UE is out of coverage, transmitting, by the UE, a synchronization signal indicating that the UE is out of coverage.
