Abstract: front page image
(EN)The present invention relates to a method and an apparatus for receiving a device-to-device (D2D) signal by a first terminal having a single RX chain in a wireless communication system. Specifically, the present invention comprises the steps of: receiving a reference synchronization window value related to a first cell for wide area network (WAN) communication and a second cell for D2D communication; determining a first D2D signal search area by applying the reference synchronization window value to a discovery pool; and setting a particular gap for a first resource area which precedes, and is located adjacent to, the first D2D signal search area and for a second resource area which follows, and is located adjacent to, the first D2D signal search area, wherein the particular gap is a time interval set for allowing the single RX chain to cover a switching operation between the WAN communication and the D2D communication.
(FR)La présente invention concerne un procédé et un appareil pour recevoir un signal de dispositif à dispositif (D2D) d’un premier terminal ayant une chaine RX unique dans un système de communication sans fil. Plus particulièrement, la présente invention comprend les étapes consistant : à recevoir une valeur de fenêtre de synchronisation de référence relative à une première cellule de communication de réseau étendu (WAN) et une seconde cellule pour une communication D2D ; à déterminer une première zone de recherche de signal D2D en appliquant la valeur de fenêtre de synchronisation de référence à un groupe de découverte ; et à régler un espace particulier pour une première zone de ressource qui précède et est située de manière adjacente à la première zone de recherche de signal D2D et une seconde zone de ressource qui suit et est située de manière adjacente à la première zone de recherche de signal D2D, l'espace particulier étant un intervalle de temps réglé pour permettre à la chaîne RX unique de couvrir une opération de commutation entre la communication WAN et la communication D2D.
(KO)본 발명은 무선 통신 시스템에서 단일 수신 체인(Single RX chain)을 가지는 제 1 단말의 D2D(Device-to-Device) 신호 수신 방법 및 장치에 관한 것 이다. 구체적으로, WAN(Wide Area Network) 통신을 위한 제 1 셀 및 D2D(Device-to-Device) 통신을 위한 제 2 셀과 관련된 참조 동기화 윈도우 (Reference Synchronization Window) 값을 수신하는 단계, 디스커버리 풀 (discovery pool)에 참조 동기화 원도우 값이 적용된 제 1 D2D 신호 검색 영역 을 결정하는 단계; 및 제 1 D2D 신호 검색 영역의 이전에 인접하여 위치하는 제 1 자원 영역 및 제 1 D2D 신호 검색 영역의 이후에 인접하여 위치하는 제 2 자 원 영역에 대하여 특정 갭(gap)을 설정하는 단계를 포함하며, 특정 갭은, 단일 수신 체인이 WAN 통신 및 D2D 통신 사이의 전환(switching) 동작을 커버하기 위 하여 설정된 시간 구간인 것을 특징으로 한다.
