METHOD OF ALLOCATING RADIO RESOURCES FOR DEVICE-TO-DEVICE COMMUNICATION IN CELLULAR COMMUNICATION SYSTEM
First Claim
1. A resource allocation method of a base station for a device-to-device (D2D) communication link based on a cellular communication system, comprising:
- 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.

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.

9. An operation method of a terminal which operates with resources allocated by a base station, for a device-to-device (D2D) communication link based on a cellular communication system, comprising:
-
receiving operation information which includes information about one or more resource allocation patterns available for the D2D communication link, according to each D2D communication link; reporting a status of a data buffer to be transmitted to a counterpart terminal to the base station; receiving an indication value which indicates at least one of the resource allocation patterns from the base station, based on the buffer status report (BSR); and performing data transmission to or data reception from the counterpart terminal of the D2D communication link based on the resource allocation pattern specified by the indication value. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
