Abstract:
(EN) Provided are a method and a device for performing device-to-device communication by sharing an uplink resource and a sidelink resource in a wireless communication system. Particularly, a first terminal receives, from a base station, beam scanning signals and a first threshold value. The first terminal generates first reception beam information including beam information of a signal received at a signal intensity greater than or equal to the first threshold value, among the beam scanning signals. The first terminal receives second reception beam information from the base station. The second reception beam information includes beam information of a first uplink signal received by the base station from a second terminal. The first terminal transmits a sidelink signal through the sidelink resource by using a beam obtained by excluding a third reception beam from a first reception beam. The third reception beam is a beam of the first terminal for receiving a signal transmitted using a transmission beam of the base station in the same direction as a second reception beam. The sidelink resource is overlapped with the uplink resource in time and frequency domains.
(FR) L'invention concerne un procédé et un dispositif permettant de réaliser une communication de dispositif à dispositif par partage d'une ressource de liaison montante et d'une ressource de liaison latérale dans un système de communication sans fil. En particulier, un premier terminal reçoit, d'une station de base, des signaux de balayage de faisceau et une première valeur de seuil. Le premier terminal génère des premières informations de faisceau de réception comportant des informations de faisceau d'un signal reçu à une intensité de signal supérieure ou égale à la première valeur de seuil, parmi les signaux de balayage de faisceau. Le premier terminal reçoit des secondes informations de faisceau de réception en provenance de la station de base. Les secondes informations de faisceau de réception comportent des informations de faisceau d'un premier signal de liaison montante reçu par la station de base en provenance d'un second terminal. Le premier terminal transmet un signal de liaison latérale au moyen de la ressource de liaison latérale à l'aide d'un faisceau obtenu par exclusion d'un troisième faisceau de réception dans un premier faisceau de réception. Le troisième faisceau de réception est un faisceau du premier terminal permettant de recevoir un signal transmis à l'aide d'un faisceau de transmission de la station de base dans la même direction qu'un deuxième faisceau de réception. La ressource de liaison latérale est chevauchée par la ressource de liaison montante dans les domaines temporel et de fréquence.
(KO) 무선 통신 시스템에서 상향링크 자원과 사이드링크 자원을 공유하여 단말 간 통신을 수행하는 방법 및 기기가 제공된다. 구체적으로, 제1 단말은 기지국으로부터 빔 스캐닝 신호 및 제1 임계 값을 수신한다. 제1 단말은 빔 스캐닝 신호 중 제1 임계 값 이상의 신호 세기로 수신된 신호의 빔 정보를 포함하는 제1 수신 빔 정보를 생성한다. 제1 단말은 기지국으로부터 제2 수신 빔 정보를 수신한다. 제2 수신 빔 정보는 기지국이 제2 단말로부터 수신한 제1 상향링크 신호의 빔 정보를 포함한다. 제1 단말은 제1 수신 빔에서 제3 수신 빔을 제외한 빔을 사용하여 사이드링크 신호를 상기 사이드링크 자원을 통해 전송한다. 제3 수신 빔은 제2 수신 빔과 동일한 방향의 기지국의 송신 빔을 사용하여 전송된 신호를 수신하는 제1 단말의 빔이다. 사이드링크 자원은 상향링크 자원과 시간 및 주파수 영역에서 중첩된다.
