Title (EN) METHOD FOR REPORTING CHANNEL STATE AND APPARATUS THEREFOR IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ POUR RAPPORTER UN ÉTAT DE CANAL ET APPAREIL ASSOCIÉ DANS UN SYSTÈME DE COMMUNICATION SANS FIL
(KO) 무선 통신 시스템에서 채널 상태 보고 방법 및 이를 위한 장치
Abstract: front page image
(EN)The present invention according to one embodiment comprises the steps of: receiving linear-combination (LC) code word-based channel state reporting configuration, which is expressed by parameters comprising an LC coefficient and a phase differential (co-phase) value between antenna groups having mutually different polarization characteristics; measuring a downlink reference signal for a channel state reporting in accordance with the received channel state reporting configuration; and transmitting, to a base station, the LC code book-based channel state report corresponding to the reference signal measurement, wherein the channel state reporting can only support a broadband reporting mode.
(FR)Conformément à un mode de réalisation, la présente invention comprend les étapes consistant : à recevoir une configuration de rapport d’état de canal basé sur un mot de code de combinaison linéaire (LC), qui est exprimée par des paramètres comprenant un coefficient de LC et une valeur de différentiel de phase (co-phase) entre des groupes d’antennes ayant des caractéristiques de polarisation mutuellement différentes ; à mesurer un signal de référence de liaison descendante pour un rapport d’état de canal conformément à la configuration de rapport d’état de canal reçue ; et à transmettre, à une station de base, le rapport d’état de canal basé sur un livre de codes de LC correspondant à la mesure de signal de référence, le rapport d’état de canal pouvant prendre en charge uniquement un mode de rapport à large bande.
(KO)본 발명의 일 실시예에 따른 선형-조합(linear-combination; LC) 계수 및 서로 다른 편파 특성을 갖는 안테나 그룹 간의 위상 차이(이하, "코-페이즈(co-phase)") 값을 포함하는 파라미터들로 표현되는 LC 코드워드 기반의 채널 상태 보고 설정을 수신하는 단계; 상기 수신된 채널 상태 보고 설정에 따라 채널 상태 보고를 위해 하향링크 참조 신호를 측정하는 단계; 및 상기 참조 신호의 측정에 따라 상기 LC 코드북 기반의 채널 상태 보고를 기지국으로 전송하는 단계를 포함하고, 상기 채널 상태 보고는 광대역 보고 모드만 지원할 수 있다.
