Abstract:
(EN) The present application proposes a method for receiving a demodulation-reference signal (DM-RS)-based downlink data signal from a base station by a terminal in a multiple-antenna-based wireless communication system. Specifically, the method comprises the steps of: receiving information relating to a linear coupling coefficient of a DM-RS antenna port from the base station; and receiving, from the base station, the downlink data signal to which a precoder for mapping the signal to a reference DM-RS antenna port and at least one auxiliary DM-RS antenna port among a plurality of DM-RS antenna ports is applied, wherein the precoder is to map the downlink data signal to the reference DM-RS antenna port and map the downlink data signal to the at least one auxiliary DM-RS antenna port by applying the linear coupling coefficient.
(FR) La présente invention concerne un procédé de réception d'un signal de données de liaison descendante à base de signal de référence de démodulation (DM-RS) provenant d'une station de base dans un système de communication sans fil à antennes multiples. Plus précisément, le procédé consiste : à recevoir, de la station de base, des informations, relatives à un coefficient de couplage linéaire d'un port d'antenne DM-RS ; à recevoir, de la station de base, le signal de données de liaison descendante auquel est appliqué un pré-codeur pour mapper le signal sur un port d'antenne DM-RS de référence et sur au moins un port d'antenne DM-RS auxiliaire parmi une pluralité de ports d'antenne DM-RS, le pré-codeur étant destiné à mapper le signal de données de liaison descendante sur le port d'antenne DM-RS de référence et à mapper le signal de données de liaison descendante sur le ou les ports d'antenne DM-RS auxiliaires en appliquant le coefficient de couplage linéaire.
(KO) 본 출원에서는 다중 안테나 기반 무선 통신 시스템에서 단말이 기지국으로부터 DM-RS (Demodul at ion-Reference Signal ) 기반 하향링크 데이터 신호를 수신하는 방법을 제안한다. 구체적으로, 상기 방법은, 상기 기지국으로부터 DM-RS 안테나 포트의 선형 결합 계수에 관한 정보를 수신하는 단계; 및 상기 기지국으로부터 복수의 DM-RS 안테나 포트들 중 기준 DM-RS 안테나 포트 및 적어도 하나의 보조 DM-RS 안테나 포트로의 맵핑을 위한 프리코더가 적용된 상기 하향링크 데이터 신호를 수신하는 단계를 포함하고, 상기 프리코더는, 상기 하향링크 데이터 신호를 상기 기준 DM-RS 안테나 포트로 맵핑하고, 상기 하향링크 데이터 신호를 상기 적어도 하나의 보조 DM-RS 안테나 포트로 상기 선형 결합 계수를 적용하여 맵핑하기 위한 것을 특징으로 한다.
