Method and system for handling device to device (D2D) communication
First Claim
1. A method for reducing signaling overhead in device-to-device (D2D) communication by a terminal, the method comprising:
- transmitting, via radio resource control (RRC) signaling, a terminal information message including a destination information list, the destination information list including a plurality of destination identities for which the terminal requests to assign resources for D2D communication;
transmitting, based on a buffer status report being triggered, the buffer status report, the buffer status report including an index indicating a destination identity in the destination information list, a length of the index being less than a length of the destination identity; and
receiving resource allocation information based on the index, wherein the length of the index is 4 bits and the length of the destination identity is 24 bits.

Abstract
A system and a method for a base station to reduce signaling overhead in device-to-device (D2D) communication are provided. The method includes a list of one or more destination identities (IDs) in a signaling message from at least one of UE and source base station, receiving a destination index in a buffer status report (BSR) from UE to request dedicated resources for transmitting D2D communication packets to a destination, determining the destination ID corresponding to destination index received in the BSR using the list of one or more destination IDs received from at least one of UE and source base station wherein the destination index is the index of destination ID in the list of destination IDs received, and allocating resources to the UE based on the determined destination ID.
