Title (EN) PILOT TRANSMISSION METHOD IN A WIRELESS COMMUNICATION SYSTEM
(FR) PROCEDE D'EMISSION DE SIGNAL PILOTE DANS UN SYSTEME DE COMMUNICATION SANS FIL
(KO) 무선통신 시스템에서 파일럿 전송방법
Abstract: front page image
(EN)The present invention relates to a pilot transmission method in a wireless communication system, including the steps of: transmitting a first pilot for channel measurement through a first transmission period; and transmitting a second pilot for channel measurement through a second transmission period subsequent to the first transmission period. The first transmission period and the second transmission period include a plurality of sub-bands, and parts of the plurality of sub- bands use a predetermined pre-coding and the residual sub-bands use a non-predetermined pre-coding. One of the first pilot and the second pilot is carried on the sub-band which uses the predetermined pre-coding, and the other of the first pilot and the second pilot is carried on the entirety of the plurality of sub-bands.
(FR)L'invention concerne un procédé d'émission de signal pilote dans un système de communication sans fil, consistant : à émettre un premier signal pilote pour mesurer un canal sur une première période d'émission; et à émettre un deuxième signal pilote pour mesurer un canal sur une deuxième période d'émission ultérieure à la première période. La première et la deuxième périodes d'émission comprennent une pluralité de sous-bandes et des parties de cette pluralité de sous-bandes mettent en oeuvre un pré-codage prédéterminé et les sous-bandes résiduelles mettent en oeuvre un pré-codage non prédéterminé. Le premier signal pilote ou le deuxième signal pilote est transporté sur la sous-bande qui met en oeuvre le pré-codage prédéterminé et l'autre signal pilote est transporté sur l'intégralité de la pluralité de sous-bandes.
(KO)무선통신 시스템에서 파일럿 전송방법은 제1 전송구간을 통하여 채널측정을 위한 제1 파일럿을 전송하는 단계, 및 상기 제1 전송구간에 시간적으로 뒤따르는 제2 전송구간을 통하여 채널측정을 위한 제2 파일럿을 전송하는 단계를 포함하되, 상기 제1 전송구간 및 상기 제2 전송구간은 복수의 서브밴드를 포함하고, 상기 복수의 서브밴드 중 일부의 서브밴드는 미리 결정된 프리코딩을 이용하고 나머지 서브밴드는 미리 결정되지 않는 프리코딩을 이용하며, 상기 제1 파일럿 및 상기 제2 파일럿 중 어느 하나는 상기 미리 결정된 프리코딩을 이용하는 서브밴드에만 실리고 다른 하나는 상기 복수의 서브밴드 전체에 실린다.
