Abstract:
(EN) According to various embodiments, disclosed are a method by which a terminal simultaneously transmits messages in at least two carriers in a wireless communication system supporting device to device (D2D) communication, and an apparatus therefor. Particularly, disclosed are a method by which a terminal simultaneously transmits messages in at least two carriers, and an apparatus therefor, the method comprising the steps of: independently sensing, by a carrier, a transmission resource, and calculating the ratio of transmission resources, which can be simultaneously transmitted on at least two carriers, on the basis of a result of the sensing by the carrier; setting the sensed transmittable transmission resource as a transmission candidate resource when the calculated transmission resource ratio is greater than or equal to a preset threshold ratio; and selecting a transmission resource to be used for the message transmission in each of at least two carriers within the transmission candidate resource.
(FR) Selon divers modes de réalisation, l'invention concerne un procédé par lequel un terminal transmet simultanément des messages dans au moins deux porteuses dans un système de communication sans fil prenant en charge une communication de dispositif à dispositif (D2D), et un appareil associé. En particulier, l'invention concerne un procédé par lequel un terminal transmet simultanément des messages dans au moins deux porteuses, et un appareil associé, le procédé comprenant les étapes suivantes : détection indépendante, par une porteuse, d'une ressource de transmission, et calcul du rapport de ressources de transmission, qui peut être simultanément transmise sur au moins deux porteuses, sur la base d'un résultat de la détection par la porteuse ; réglage de la ressource de transmission pouvant être transmise détectée en tant que ressource candidate de transmission lorsque le rapport de ressources de transmission calculé est supérieur ou égal à un rapport seuil prédéfini ; et sélection d'une ressource de transmission à utiliser pour la transmission de message dans chacune d'au moins deux porteuses à l'intérieur de la ressource candidate de transmission.
(KO) 다양한 실시예에 따른 단말 간 통신 (D2D; Device to Device communication)을 지원하는 무선통신시스템에서 단말이 적어도 둘 이상의 캐리어에서 메시지를 동시 전송하는 방법 및 이를 위한 장치가 개시된다. 구체적으로, 캐리어 별로 전송 자원을 독립적으로 센싱하고, 상기 캐리어 별 센싱 결과에 기초하여 상기 적어도 둘 이상의 캐리어 상에서 동시 전송이 가능한 전송 자원의 비율을 산출하는 단계, 상기 산출된 전송 자원 비율이 미리 설정된 임계 비율 이상이면, 상기 센싱된 전송 가능한 전송 자원을 전송 후보 자원으로 설정하는 단계 및 상기 전송 후보 자원 내에서 상기 적어도 둘 이상의 캐리어 각각에서 상기 메시지 전송에 사용되는 전송 자원을 선택하는 단계를 포함하는 단말이 적어도 둘 이상의 캐리어에서 메시지를 동시 전송하는 방법 및 이를 위한 장치가 개시된다.
