Title (EN) METHOD FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
(FR) PROCÉDÉ SERVANT À COMMUNIQUER DES INFORMATIONS D'ÉTAT DE CANAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET APPAREIL ASSOCIÉ
(KO) 무선 통신 시스템에서 채널 상태 정보를 보고하는 방법 및 이를 위한 장치
Abstract: front page image
(EN)The present invention relates to a method for enabling a terminal to report channel state information in a wireless communication system for supporting coordinated multi point (CoMP) transmission. Specifically, the method for enabling the terminal to report the channel state information in the wireless communication system for supporting CoMP transmission includes the steps of: receiving a reference signal from a serving cell and one or more cooperated cells; forming the channel state information for the CoMP transmission on the basis of the reference signal; and reporting the channel state information through a physical uplink shared channel to the serving cell, wherein the channel state information includes channel quality indicator (CQI) information and precoding matrix index (PMI) information, the CQI information includes a wideband CQI and a CQI for each selected sub-band of the CoMP transmission, and the PMI information includes a wideband PMI and a PMI for each of the selected sub-bands.
(FR)La présente invention concerne un procédé permettant à un terminal de communiquer des informations d'état de canal dans un système de communication sans fil afin de supporter une transmission multipoint coordonnée (CoMP). Spécifiquement, le procédé permettant au terminal de communiquer des informations d'état de canal dans le système de communication sans fil afin de supporter la transmission CoMP comprend les étapes consistant : à recevoir un signal de référence depuis une cellule serveuse et une ou plusieurs cellules coopérées; à former les informations d'état de canal pour la transmission CoMP sur la base du signal de référence; et à communiquer les informations d'état de canal au moyen d'un canal partagé de liaison montante physique à la cellule serveuse, les informations d'état de canal comprenant des informations indicatrices de qualité de canal (CQI) et des informations d'index de matrice de précodage (PMI), les informations de CQI comprenant un CQI à large bande et un CQI pour chaque sous-bande sélectionnée de la transmission CoMP, et les informations PMI comprenant un PMI de large bande et un PMI pour chacune des sous-bandes sélectionnées.
(KO)본 출원에서는 CoMP(Coordinated Multi Point) 전송을 지원하는 무선 통신 시스템에서 단말이 채널 상태 정보를 보고하는 방법이 개시된다. 구체적으로, 서빙 셀 및 하나 이상의 협력 셀로부터 참조 신호를 수신하는 단계, 상기 참조 신호에 기반하여, 상기 CoMP 전송을 위한 채널 상태 정보를 구성하는 단계, 및 상기 채널 상태 정보를 상향링크 물리 공용 채널(Physical Uplink Shared CHannel)을 통하여 상기 서빙 셀로 보고하는 단계를 포함하고, 상기 채널 상태 정보는 채널 품질 지시자(Channel Quality Indicator; CQI) 정보 및 프리코딩 행렬 인덱스(Precoding Matrix Index; PMI) 정보를 포함하고, 상기 CQI 정보는 광대역(Wideband) CQI 및 상기 CoMP 전송을 위하여 선택된 서브밴드 각각에 대한 CQI를 포함하며, 상기 PMI 정보는 광대역(Wideband) PMI 및 상기 선택된 서브밴드 각각에 대한 PMI를 포함하는 것을 특징으로 한다.
