Abstract: front page image
(EN) Disclosed is a method for estimating the difference in inter-symbol phase rotations in a wireless communication system. The method, which is carried out by a terminal, comprises the steps of: receiving, from a base station, control data associated with the transmission of a signal utilized in estimating the difference in inter-symbol phase rotations; receiving from the base station, by means of a particular resource, a first signal utilized in estimating the phase rotations; estimating the difference in inter-symbol phase rotations by means of the received first signal; receiving from the base station, by means of a symbol following the transmission symbol of the first signal, a second signal utilized for estimating the phase rotations; estimating the difference in inter-symbol phase rotations by means of the received second signal; and decoding the received signal in consideration of the difference in phase rotations estimated by means of the second signal.
(FR) L'invention concerne un procédé d'estimation de la différence dans des rotations de phase inter-symboles dans un système de communication sans fil. Le procédé, qui est réalisé par un terminal, comporte les étapes consistant à: recevoir, en provenance d'une station de base, des données de commande associées à l'émission d'un signal utilisé dans l'estimation de la différence dans des rotations de phase inter-symboles; recevoir en provenance de la station de base, au moyen d'une ressource particulière, un premier signal utilisé dans l'estimation des rotations de phase; estimer la différence dans des rotations de phase inter-symboles au moyen du premier signal reçu; recevoir en provenance de la station de base, au moyen d'un symbole suivant l'émission du symbole du premier signal, un deuxième signal utilisé pour estimer les rotations de phase; estimer la différence dans des rotations de phase inter-symboles au moyen du deuxième signal reçu; et décoder le signal reçu en tenant compte de la différence de rotations de phase estimée au moyen du deuxième signal.
(KO) 본 명세서는 무선 통신 시스템에서 심볼(symbol) 간 위상 회전(phase rotation) 차이를 추정하는 방법에 있어서, 단말에 의해 수행되는 방법은, 상기 심볼 간 위상 회전(phase rotation) 차이 추정에 사용되는 신호의 전송과 관련된 제어 정보를 기지국으로부터 수신하는 단계; 특정 자원을 통해 위상 회전 추정에 사용되는 제 1 신호를 상기 기지국으로부터 수신하는 단계; 상기 수신된 제 1 신호를 이용하여 심볼 간 위상 회전 차이를 추정하는 단계; 상기 제 1 신호의 전송 심볼 이후의 심볼을 통해 위상 회전 추정에 사용되는 제 2 신호를 상기 기지국으로부터 수신하는 단계; 상기 수신된 제 2 신호를 이용하여 심볼 간 위상 회전 차이를 추정하는 단계; 및 상기 제 2 신호를 통해 추정된 위상 회전 차이를 고려하여 수신 신호를 디코딩(decoding)하는 단계를 포함하여 이루어지는 것을 특징으로 한다.
