Abstract: front page image
(EN)Disclosed in the present application is a method for transmitting a sounding reference signal (SRS) from a terminal to a base station in a wireless communication system. More specifically, the method comprises: a step of establishing a first subframe set and a second subframe set through an upper layer; a step of receiving, from the base station, a triggering indicator of the sounding reference signal; and a step of transmitting the sounding reference signal from a specific subframe to the base station, according to the triggering indicator, wherein each of the first subframe set and the second subframe set is associated with a power control process for transmitting an uplink data channel, and wherein the transmission power of the sounding reference signal is determined according to the bit size and/or the field value of the triggering indicator.
(FR)La présente invention se rapporte à un procédé permettant de transmettre depuis un terminal un signal de référence de sondage (SRS pour Sounding Reference Signal) à une station de base dans un système de communication sans fil. De façon plus précise, le procédé comprend : une étape consistant à établir un premier ensemble de sous-trames et un second ensemble de sous-trames à travers une couche supérieure ; une étape consistant à recevoir, de la station de base, un indicateur de déclenchement du signal de référence de sondage ; et une étape consistant à transmettre à la station de base le signal de référence de sondage à partir d'une sous-trame spécifique selon l'indicateur de déclenchement, le premier ensemble de sous-trames et le second ensemble de sous-trames étant chacun associé à un procédé de commande de puissance permettant de transmettre un canal de données de liaison montante et la puissance de transmission du signal de référence de sondage étant déterminée selon la taille de bit et/ou la valeur de champ de l'indicateur de déclenchement.
(KO)본 출원에서는 무선 통신 시스템에서 단말이 기지국으로 사운딩 참조 신호(Sounding Reference Signal; SRS)를 송신하는 방법이 개시된다. 구체적으로, 상기 방법은, 상위 계층을 통하여, 제 1 서브프레임 세트 및 제 2 서브프레임 세트를 설정하는 단계; 상기 기지국으로부터 상기 사운딩 참조 신호의 트리거링 지시자를 수신하는 단계; 및 상기 트리거링 지시자에 따라, 상기 사운딩 참조 신호를 상기 기지국으로 특정 서브프레임에서 송신하는 단계를 포함하고, 상기 제 1 서브프레임 세트 및 상기 제 2 서브프레임 세트 각각은 상향링크 데이터 채널 전송을 위한 전력 제어 프로세스와 연관되고, 상기 사운딩 참조 신호의 송신 전력은 상기 트리거링 지시자의 비트 사이즈 및 필드 값 중 적어도 하나에 따라 결정되는 것을 특징으로 한다.
