Abstract: front page image
(EN)An embodiment of the present invention relates to a method for a device-to-device (D2D) terminal transmitting a physical sidelink shared channel (PSSCH) in a wireless communication system. The PSSCH transmission method comprises the steps of: receiving a physical sidelink control channel (PSCCH) and a PSSCH transmitted in a resource region indicated by means of the PSCCH; if an energy measurement value with respect to the PSSCH is greater than a preset threshold, selecting a transmission resource excluding the resource region in which the PSSCH has been transmitted; and transmitting a D2D signal by means of the selected transmission resource, wherein the threshold has a value that varies in accordance with whether or not the PSSCH is retransmission or the redundancy version (RV) of the PSSCH.
(FR)Un mode de réalisation de la présente invention concerne un procédé pour un terminal de dispositif à dispositif (D2D) transmettant un canal partagé de liaison latérale physique (PSSCH, "physical sidelink shared channel") dans un système de communication sans fil. Le procédé de transmission PSSCH comprend les étapes consistant à : recevoir un canal de commande de liaison latérale physique (PSCCH, "physical sidelink control channel") et un PSSCH transmis dans une région de ressource indiquée au moyen du PSCCH ; sélectionner, si une valeur de mesure d'énergie par rapport au PSSCH est supérieure à un seuil prédéfini, une ressource de transmission excluant la région de ressource dans laquelle le PSSCH a été transmis ; et transmettre un signal D2D au moyen de la ressource de transmission sélectionnée, le seuil ayant une valeur qui varie selon que le PSSCH est une retransmission ou une version de redondance (RV, "redundancy version") du PSSCH.
(KO)본 발명의 일 실시예는, 무선통신시스템에서 D2D(Device-to-Device) 단말이 PSSCH(Physical sidelink shared channel)를 전송하는 방법에 있어서, PSCCH 및 상기 PSCCH (Physical sidelink control channel)에 의해 지시되는 자원 영역에서 전송되는 PSSCH를 수신하는 단계; 상기 PSSCH에 대한 에너지 측정 값이 미리 설정된 임계값보다 큰 경우, 상기 PSSCH가 전송된 자원 영역을 제외하고 전송 자원을 선택하는 단계; 및 상기 선택된 전송 자원을 사용하여 D2D 신호를 전송하는 단계를 포함하며, 상기 임계값은, 상기 PSSCH가 재전송인지 여부 또는 상기 PSSCH의 RV(Redundancy Version)에 따라 상이한 값을 갖는 것인, PSSCH 전송 방법이다.
