Abstract

본 발명은 무선 통신 시스템에서 디바이스 간 직접 통신 서비스(D2D)를 수행하는 방법 및 장치를 제공한다. 특히, D2D 통신을 지원하는 D2D 단말들을 구별하고, 동일한 어플리케이션을 사용하는 D2D 단말들에 대하여 탐색 그룹(discovery group)을 형성하며, 상기 탐색 그룹에 따라 탐색 타이밍을 설정함을 특징으로 한다. 여기서, 상기 탐색 타이밍에 동일한 탐색 그룹에 속하는 D2D 단말들이 활성화 상태(active)로 천이하여, D2D 탐색을 위해 정해진 시간과 주파수 자원을 이용하여 신호를 송수신한다. 이때, 상기 상기 탐색 타이밍이 탐색 그룹에 따라 가변된 값을 가지도록 설정하는 것을 특징으로 한다.
