Abstract: front page image
(EN)Disclosed is a method for transmitting, by a terminal, feedback information to a network for partial beamforming based on a multi-antenna in a wireless communication system. Specifically, the method comprises: a step of receiving, from the network, reference signals corresponding to antenna sections included in the multi-antenna; a step of selecting one or more beamforming mode among beamforming modes included in a candidate beamforming mode set on the basis of the reference signals, and forming feedback information related to the selected one or more beamforming modes; and a step of transmitting the feedback information to the network, and the feedback information includes a pre-coding matrix index corresponding to at least one of the antenna sections and connection coefficient information for connecting the antenna sections.
(FR)L'invention porte sur un procédé pour transmettre, par un terminal, des informations de rétroaction à un réseau pour formation de faisceau partielle sur la base d'une antenne multiple dans un système de communication sans fil. Plus particulièrement, le procédé comprend : une étape consistant à recevoir, en provenance du réseau, des signaux de référence correspondant à des sections d'antenne incluses dans l'antenne multiple ; une étape consistant à sélectionner un ou plusieurs modes de formation de faisceau parmi des modes de formation de faisceau inclus dans un ensemble de modes de formation de faisceaux candidats sur la base des signaux de référence, et à former des informations de rétroaction concernant le ou les modes de formation de faisceau sélectionnés ; et une étape consistant à transmettre les informations de rétroaction au réseau, les informations de rétroaction comprenant un indice de matrice de précodage correspondant à au moins une des sections d'antenne et des informations de coefficient de connexion pour connecter les sections d'antenne.
(KO)본 출원에서는 무선 통신 시스템에서 다중 안테나 기반 부분 빔포밍을 위하여 단말이 네트워크로 피드백 정보를 송신하는 방법이 개시된다. 구체적으로, 상기 방법은, 상기 네트워크로부터 상기 다중 안테나에 포함된 안테나 구획들에 대응하는 참조 신호들을 수신하는 단계; 상기 참조 신호들에 기반하여, 후보 빔포밍 모드 집합에 포함된 빔포밍 모드들 중 하나 이상의 빔포밍 모드를 선택하고, 상기 선택된 하나 이상의 빔포밍 모드에 관한 상기 피드백 정보를 구성하는 단계; 및 상기 피드백 정보를 상기 네트워크로 송신하는 단계를 포함하고, 상기 피드백 정보는, 상기 안테나 구획들 중 적어도 하나에 대응하는 프리코딩 행렬 인덱스와 상기 안테나 구획들을 연결하기 위한 연결 계수 정보를 포함하는 것을 특징으로 한다.
