Title (EN) METHOD FOR ESTIMATING PHASE ROTATION OF TRANSMISSION PORT IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
(FR) PROCÉDÉ D'ESTIMATION DE ROTATION DE PHASE DE PORT DE TRANSMISSION DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET APPAREIL ASSOCIÉ
(KO) 무선 통신 시스템에서 전송 포트의 위상 회전을 추정하기 위한 방법 및 이를 위한 장치
Abstract:
(EN) The present specification discloses a method for estimating a phase rotation of a transmission port by a terminal in a wireless communication system, the method comprising the steps of: receiving one or more demodulation reference signals (DMRSs) from a base station in a DMRS symbol; receiving at least one first reference signal, used to estimate a phase rotation of a DMRS port, from the base station in a particular resource region; and estimating the phase rotation of the DMRS port on the basis of the at least one first reference signal.
(FR) La présente invention concerne un procédé d'estimation d'une rotation de phase d'un port de transmission par un terminal dans un système de communication sans fil, le procédé comprenant les étapes consistant à : recevoir un ou plusieurs signaux de référence de démodulation (DMRS) en provenance d'une station de base dans un symbole DMRS ; recevoir au moins un premier signal de référence, utilisé pour estimer une rotation de phase d'un port DMRS, en provenance de la station de base dans une région de ressource particulière ; et estimer la rotation de phase du port DMRS sur la base du ou des premiers signaux de référence.
(KO) 본 명세서는 무선 통신 시스템에서 전송 포트 (port )의 위상 회전 (phase rotation)을 추정하는 방법에 있어서, 단말에 의해 수행되는 방법은, 기지국으로부터 하나 또는 그 이상의 복조 참조 신호 (Demodulation Reference Signal : DMRS )들을 DMRS 심볼에서 수신하는 단계; DMRS 포트의 위상 회전 추정에 사용되는 적어도 하나의 제 1 참조 신호를 특정 자원 영역에서 상기 기지국으로부터 수신하는 단계; 및 상기 적어도 하나의 제 1 참조 신호에 기초하여 상기 DMRS 포트의 위상 회전을 추정하는 단계를 포함하는 것을 특징으로 한다.
