METHOD FOR ESTABLISHING A DEVICE-TO-DEVICE LINK CONNECTION AND SCHEDULING FOR DEVICE-TO-DEVICE COMMUNICATION AND TERMINAL RELAYING
First Claim
1. A method of operating a base station for connection configuration and scheduling for dynamic scheduling of a device-to-device (D2D) link, the method comprising:
- performing connection configuration of the D2D link;
receiving a D2D buffer status report from a first terminal that is a transmission terminal in the D2D link;
allocating D2D link resources based on the D2D buffer status report and providing resource allocation information; and
receiving channel state information of the D2D link measured by a second terminal that is a reception terminal in the D2D link.

Abstract
Disclosed is a method for establishing a device-to-device link connection and scheduling for device-to-device communication and terminal relaying. The method for operating a terminal according to the present invention comprises the following steps: receiving information on the establishment of a D2D link; reporting a state of a D2D buffer of the D2D link to a base station; and receiving information on the D2D link resource allocation based on the report on the D2D buffer state. The scheduling method for D2D communication according to the present invention enables dynamic scheduling to be performed on a subframe unit basis, and enables semi-continuous scheduling for continuous data transmission for a D2D communication link.
