Abstract

본 발명은 무선 통신 시스템에서 단일 수신 체인 (Single RX chain)을 가지는 제 1 단말의 하향링크 제어 채널 모니터링 방법 및 장치에 관한 것이다. 구체적으로， D2D(Device-to-Device) 신호 송수신과 관련된 자원 영역에 대하여 특정 갭 (gap)을 설정하는 단계 및 WAN(Wide Area Network) 통산 기반 하향링크 제어 채널에 대하여 불연속 수신 (Di scontinuous Reception, DRX) 동작에 따라 수행되는 타이머에 기반하여 모니터링하는 단계를 포함하며， 타이머는, 특정 갭 과 겹치지 않는 적어도 하나의 서브프레임들에 기반하여 카운팅되며， 특정 갭은， 단일 수신 체인이 WMN 통신 및 D2D 통신 사이의 전환 (switching) 동작을 커버하 기 위하여 설정된 시간 구간인 것을 특징으로 한다.
