Claim Text:
1. A method for assigning connection identifiers for a device-to-device communication, the method comprising: identifying unused connection identifiers among a plurality of connection identifiers that can be used for a device-to-device communication; determining candidate connection identifiers usable for a device-to-device communication with a peer device among the unused connection identifiers and a number of assignable connection identifiers that are assignable to a connection with the peer device based on data characteristics of the connection; transmitting, to the peer device, first information including the candidate connection identifiers and the determined number of assignable connection identifiers to the peer device; receiving, from the peer device, second information relating to at least two connection identifiers selected by the peer device based on the first information; and communicating with the peer device through at least two time resource regions corresponding to a group to which the at least two connection identifiers indicated by the second information belong, wherein the plurality of connection identifiers are divided into a plurality of groups, the groups each including a plurality of connection identifiers, the plurality of connection identifiers belong to each group being mapped to different time resource regions, and wherein the at least two connection identifiers indicated by the second information are selected from a single group of the plurality of groups.
