Title (EN) DEVICE AND METHOD FOR TRANSMITTING CHANNEL INFORMATION IN WIRELESS COMMUNICATION SYSTEM
(FR) DISPOSITIF ET PROCÉDÉ DE TRANSMISSION D'INFORMATIONS DE CANAUX DANS UN SYSTÈME DE COMMUNICATION SANS FIL
(KO) 무선통신 시스템에서의 채널 정보 전송 장치 및 방법
Abstract: front page image
(EN)This invention relates to a device and a method for transmitting channel information in a wireless communication system. The disclosed device and method are characterized by: estimating channels by dividing the channel matrix elements for a complex channel into a real number part and an imaginary number part; quantizing each channel which is estimated through the division into the real and imaginary number parts based on a preset boundary value; generating the channel information corresponding to the quantization value for the real and imaginary number parts of the channel matrix elements; and transmitting the generated channel information to a transmitter.
(FR)La présente invention concerne un dispositif et un procédé de transmission d'informations de canaux dans un système de communication sans fil. Le dispositif et le procédé selon l'invention se caractérisent en ce: l'estimation des canaux est effectuée par une division des éléments matriciels de canal pour un canal complexe en une partie nombre réel et une partie nombre imaginaire; la quantification de chaque canal qui est estimé par la division en parties nombre réel et nombre imaginaire sur la base d'une valeur limite préétablie; la génération des informations de canal correspondant à la valeur de quantification pour les parties nombre réel et nombre imaginaire des éléments matriciels de canal; et l'envoi, à un émetteur, des informations de canal générées.
(KO)본 발명은 무선통신 시스템에서 채널 정보를 전송하는 장치 및 방법에 관한 것이다. 본 발명에 따른 채널 정보를 전송하는 장치 및 방법은, 복소 채널에 대한 채널 행렬 요소(channel matrix element)를 실수부와 허수부로 분리하여 채널을 추정하고, 상기 실수부와 허수부로 분리 추정된 채널을 각각 기 설정된 경계값에 기초하여 양자화(quantization)하며, 상기 채널 행렬 요소의 실수부 및 허수부에 대한 양자화값에 상응하는 채널 정보를 생성하여, 상기 생성된 채널 정보를 송신단으로 전송하는 것을 특징으로 한다.
