Abstract: front page image
(EN) Provided are a method and an apparatus for performing phase tracking by a terminal in a wireless communication system. The present invention may provide a method and an apparatus for performing phase tracking, the method comprising the steps of: receiving at least one parameter from a base station, wherein the at least one parameter indicates locations of frequency tones and symbols in a specific resource area to which at least one first reference signal is mapped; receiving the at least one first reference signal used for phase tracking from the base station through the specific resource area, wherein the at least one first reference signal is mapped to a specific symbol in a time domain and a specific frequency tone in a frequency domain, the specific symbol and the specific frequency tone being different for each antenna port through which the first reference signal is transmitted; and performing the phase tracking on the basis of the at least one first reference signal.
(FR) L'invention concerne un procédé et un appareil d'exécution d'un suivi de phase dans un système de communications sans fil. La présente invention peut fournir un procédé et un appareil d’exécution d’un suivi de phase. Le procédé comprend les étapes consistant à : recevoir au moins un paramètre, d'une station de base, le ou les paramètres indiquant des emplacements de tonalités de fréquence et des symboles dans une zone de ressource spécifique sur laquelle au moins un premier signal de référence est mappé ; recevoir le ou les premiers signaux de référence utilisés pour le suivi de phase, de la station de base, via la zone de ressource spécifique, le ou les premiers signaux de référence étant mappés sur un symbole spécifique dans un domaine temporel et une tonalité de fréquence spécifique dans un domaine fréquentiel, le symbole spécifique et la tonalité de fréquence spécifique étant différents pour chaque port d'antenne via lequel le premier signal de référence est transmis ; et exécuter le suivi de phase sur la base du ou des premiers signaux de référence.
(KO) 무선 통신 시스템에서 단말이 위상 추정(Phase Tracking)을 수행하는 방법 및 장치에 관한 것이다. 본 발명에 의하면, 기지국으로부터 적어도 하나의 파라메터를 수신하되, 상기 적어도 하나의 파라메터는 적어도 하나의 제 1 참조 신호가 매핑된 특정 자원 영역의 주파수 톤 및 심볼의 위치를 나타내고, 상기 기지국으로부터 위상 추정을 위해 사용되는 상기 적어도 하나의 제 1 참조 신호를 상기 특정 자원 영역을 통해 수신하되, 상기 적어도 하나의 제 1 참조 신호는 전송되는 안테나 포트 별로 서로 다른 시간 도메인 상의 특정 심볼 및 주파수 도메인 상의 특정 주파수 톤(frequency tone)에 매핑되며, 상기 적어도 하나의 제 1 참조 신호에 기초하여 상기 위상 추정을 수행하는 단계 및 장치를 제공할 수 있다.
