Title (EN) METHOD FOR ESTIMATING INTER-SYMBOL PHASE ROTATION DIFFERENCE IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
(FR) PROCÉDÉ D'ESTIMATION DE DIFFÉRENCE DE ROTATION DE PHASE ENTRE SYMBOLES DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET APPAREIL ASSOCIÉ
(KO) 무선 통신 시스템에서 심볼 간 위상 회전 차이를 추정하기 위한 방법 및 이를 위한 장치
Abstract:
(EN) The present specification relates to a method for estimating an inter-symbol phase rotation difference in a wireless communication system, the method performed by a terminal comprises the steps for: receiving, from a base station through a DMRS symbol, a plurality of demodulation reference signals (DMRS), each signal corresponding to each layer; receiving at least one first reference signal used for an estimation of the intersymbol phase rotation difference from the base station via a specific resource region; and estimating the intersymbol phase rotation difference on the basis of at least one of the plurality of DMRSs or the at least one first reference signal.
(FR) La présente invention concerne un procédé d'estimation d'une différence de rotation de phase entre symboles dans un système de communication sans fil, le procédé mis en œuvre par un terminal comprenant les étapes consistant à : recevoir, en provenance d'une station de base, par l'intermédiaire d'un symbole DMRS, une pluralité de signaux de référence de démodulation (DMRS), chaque signal correspondant à chaque couche; recevoir au moins un premier signal de référence utilisé pour une estimation de la différence de rotation de phase entre symboles en provenance de la station de base par l'intermédiaire d'une région de ressource spécifique; et estimer la différence de rotation de phase entre symboles sur la base d'au moins un signal de la pluralité de DMRS ou dudit premier signal de référence.
(KO) 본 명세서는 무선 통신 시스템에서 심볼(symbol) 간 위상 회전(phase rotation) 차이를 추정하는 방법에 있어서, 단말에 의해 수행되는 방법은, 레이어(layer) 별로 각각 대응하는 복수의 DMRS(Demodulation Reference Signal)들을 DMRS 심볼을 통해 기지국으로부터 수신하는 단계; 상기 심볼 간 위상 회전(phase rotation) 차이 추정에 사용되는 적어도 하나의 제 1 참조 신호를 특정 자원 영역을 통해 상기 기지국으로부터 수신하는 단계; 및 상기 복수의 DMRS들 또는 상기 적어도 하나의 제 1 참조 신호 중 적어도 하나에 기초하여 상기 심볼 간 위상 회전 차이를 추정하는 단계를 포함하여 이루어지는 것을 특징으로 한다.
