Abstract:
(EN) The present invention relates to a method by which a terminal performs phase tracking in a wireless communication system, and a device. According to the present invention, provided are a method and a device, the method comprising a step of receiving, from a base station through a DMRS symbol, a demodulation reference signal (DMRS), which has been set according to a particular pattern, and receiving, from the base station, a plurality of reference signals used in the phase tracking, wherein the plurality of reference signals are transmitted on a particular antenna port and received through a particular resource region, which is the same as that of at least one other reference signal transmitted on another antenna port for the phase tracking, and the phase tracking is performed on the basis of the DMRS and/or the plurality of reference signals.
(FR) La présente invention concerne un procédé selon lequel un terminal réalise un suivi de phase dans un système de communication sans fil, et un dispositif associé. Selon la présente invention, le procédé comprend une étape consistant à recevoir, à partir d'une station de base par l'intermédiaire d'un symbole DMRS, un signal de référence de démodulation (DMRS), qui a été réglé selon un motif particulier, et à recevoir, en provenance de la station de base, une pluralité de signaux de référence utilisés dans le suivi de phase, la pluralité de signaux de référence étant transmis sur un port d'antenne particulier et reçus par l'intermédiaire d'une région de ressource particulière, qui est identique à celle d'au moins un autre signal de référence transmis sur un autre port d'antenne pour le suivi de phase, et le suivi de phase est réalisé sur la base du DMRS et/ou de la pluralité de signaux de référence.
(KO) 무선 통신 시스템에서 단말이 위상 추정(Phase Tracking)을 수행하는 방법 및 장치에 관한 것이다. 본 발명에 의하면, 특정 패턴에 따라 설정된 DMRS(Demodulation Reference Signal)를 DMRS 심볼을 통해 기지국으로부터 수신하고, 상기 위상 추정에 사용되는 복수의 참조 신호를 상기 기지국으로부터 수신하되, 상기 복수의 참조 신호는 특정 안테나 포트 상에서 전송되며, 상기 위상 추정을 위해서 다른 안테나 포트 상에서 전송되는 적어도 하나의 다른 참조 신호와 동일한 특정 자원 영역을 통해서 수신되고, 상기 DMRS 또는 상기 복수의 참조 신호 중 적어도 하나에 기초하여 상기 위상 추정을 수행하는 단계를 포함하는 방법 및 장치를 제공할 수 있다.
