Title (EN) METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING APERIODIC REFERENCE SIGNAL IN COMMUNICATION SYSTEM USING MULTIPLE COMPONENT CARRIERS
(FR) PROCÉDÉ ET DISPOSITIF POUR TRANSMETTRE ET RECEVOIR UN SIGNAL DE RÉFÉRENCE APÉRIODIQUE DANS UN SYSTÈME DE COMMUNICATION EN UTILISANT DE MULTIPLES PORTEUSES COMPOSANTES

Abstract:
(EN) The present invention relates to a wireless communication system, and particularly, the invention transmits an aperiodic reference signal in a communication system using multiple component carriers, wherein: component carrier identification information, which is the target of an aperiodic reference signal transmission, is included in downlink control information that is transmitted through a physical control channel; and transmission parameter information for an aperiodic reference signal transmission of a corresponding CC is transmitted through separate signaling. According to the present invention, a terminal is capable of stably transmitting an aperiodic reference signal (for example, A-SRS) in a communication system using a plurality of component carriers (CCs), and particularly, an uplink grant and an A-SRS grant of the information of a DCI format 4 are configured relative to different CCs, thereby indicating more efficient A-SRS transmissions in a multi-cell environment.
(FR) La présente invention concerne un système de communication sans fil, et particulièrement, l'invention transmet un signal de référence apériodique dans un système de communication en utilisant de multiples porteuses composantes. Dans ladite invention, des informations d'identification de porteuse composante, qui sont la cible d'une transmission de signal de référence apériodique, sont incluses dans des informations de commande de liaison descendante qui sont transmises par l'intermédiaire d'un canal de signalisation physique ; et des informations de paramètre de transmission pour un signal de référence apériodique transmission d'un CC correspondant sont transmises par l'intermédiaire de signalisation séparée. Selon la présente invention, un terminal est capable de transmettre de façon stable un signal de référence apériodique (par exemple, A-SRS) dans un système de communication en utilisant une pluralité de porteuses composantes (« Component Carriers » ou CC), et particulièrement, une autorisation amont et une autorisation A-SRS des informations d'un format DCI 4 sont configurées par rapport à des CC, indiquant ainsi des transmissions A-SRS plus efficaces dans un environnement à cellules multiples.
(KO) 본 발명은 무선통신 시스템, 특히 다중 요소 반송파를 이용하는 통신 시스템에서 비주기적 참조신호를 전송함에 있어서, 물리제어채널(Physical Control Channel)을 통하여 전송되는 하향링크 제어 정보(Downlink Control Information)에 비주기적 참조 신호 전송의 대상이 되는 요소 반송파(Component Carrier) 식별 정보를 포함시키고, 해당 CC의 비주기적 참조 신호 전송을 위한 전송 파라미터 정보는 별도의 시그널링은 통하여 전송한다. 본 발명을 이용하면, 복수의 요소 반송파(CC)를 이용하는 통신 시스템에서 단말이 비주기적 참조신호(예컨데 A-SRS)를 안정적으로 전송할 수 있고, 특히, DCI 포맷 4의 정보 중 상향링크 할당(UL Grant)과 A-SRS 할당이 서로 다른 CC에 대해 구성될 수 있으므로 다중 셀 환경에서 보다 효율적인 A-SRS 전송을 지시할 수 있다는 효과가 있다.
