Method of allocating radio resources for device-to-device communication in cellular communication system

Abstract

A resource allocation method of a base station for a device-to-device (D2D) communication link based on a cellular communication system includes providing operation information which includes information about one or more resource allocation patterns available for the D2D communication link to terminals which perform D2D communication according to each terminal and each D2D communication link, receiving a buffer status report (BSR) from the terminals which perform the D2D communication, and transmitting an indication value which indicates at least one of the resource allocation patterns based on the BSR. Accordingly, in the resource allocation method, low capacity of downlink control channels is required by the base station, yet flexible and efficient allocation of resources is enabled.
