Abstract
A method for resource allocation of a terminal configured to perform device-to-device (D2D) communication in a wireless communication system according to an embodiment of the present invention may comprise the steps of: receiving information on the entire available resource region of the D2D communication from a serving base station; transmitting, to the base station, a request for resource allocation required for the D2D communication based on the information on the entire available resource region and channel information of the D2D communication; and receiving, from the base station, resource allocation information for the D2D communication, determined on the basis of the request for resource allocation.
Claims7
A method for resource allocation of a User Equipment (UE) configured to perform device-to-device (D2D) communication in a wireless communication system, the method comprising:
- receiving, by the UE from a serving base station, a message including information on a transmission resource region,
- wherein the information on the transmission resource region indicates available resources to transmit D2D data for when the UE is in a condition;
- and
- transmitting, by the UE to another UE, the D2D data using a part of the available resources indicated by the information on the transmission resource region when the UE is in an out-sync condition.
A User Equipment (UE) configured to perform Device-to-Device (D2D) communication in a wireless communication system, the UE comprising:
- a transceiver;
- and
- a processor configured to:
- control the transceiver to receive, from a serving base station, a message including information on a transmission resource region,
- wherein the information on the first type transmission resource region indicates available resources to transmit D2D data for when the UE is in a condition, and
- control the transceiver to transmit the D2D data, to another UE, using a part of the available resources indicated by the information on the transmission resource region when the UE is in an out-sync condition.
