Abstract:
(EN) Disclosed in the present application is a method by which a terminal having a plurality of distributed antenna groups transmits and receives a signal in a wireless communication system. Particularly, the method comprises the steps of: calculating channel quality indicators for each of distributed antenna groups; selecting a preferred distributed antenna group among the distributed antenna groups on the basis of the channel quality indicators; and reporting information on the channel quality indicators to a base station, wherein the method further comprises a step for reporting information on the preferred distributed antenna group to the base station when the preferred distributed antenna group differs from the preselected specific distributed antenna group.
(FR) L'invention concerne un procédé permettant à un terminal comprenant une pluralité de groupes d'antennes réparties de transmettre et de recevoir un signal dans un système de communication sans fil. En particulier, le procédé consiste à : calculer des indicateurs de qualité de canal pour chacun des groupes d'antennes réparties ; sélectionner un groupe d'antennes réparties préféré parmi les groupes d'antennes réparties d’après les indicateurs de qualité de canal ; et rapporter des informations sur les indicateurs de qualité de canal à une station de base. Ledit procédé consiste également à rapporter des informations concernant le groupe d'antennes réparties préféré à la station de base lorsque le groupe d'antennes réparties préféré diffère du groupe d'antennes réparties spécifique présélectionné.
(KO) 본 출원에서는 무선 통신 시스템에서 복수의 분산 안테나 그룹들을 구비한 단말이 신호를 송수신하는 방법이 개시된다. 구체적으로, 상기 방법은, 상기 분산 안테나 그룹들 각각에 대한 채널 품질 지시자들을 산출하는 단계; 상기 채널 품질 지시자들에 기반하여, 상기 분산 안테나 그룹들 중 선호 분산 안테나 그룹을 선택하는 단계; 및 상기 채널 품질 지시자들에 대한 정보를 기지국으로 보고하는 단계를 포함하고, 상기 선호 분산 안테나 그룹이 기 선택된 특정 분산 안테나 그룹과 다른 경우, 상기 선호 분산 안테나 그룹에 대한 정보를 상기 기지국으로 보고하는 단계를 더 포함하는 것을 특징으로 한다.
