Title (EN) METHOD AND DEVICE FOR DETERMINING REFERENCE SIGNAL ANTENNA PORT FOR DOWNLINK CONTROL CHANNEL IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET DISPOSITIF POUR LA DÉTERMINATION DE PORT D'ANTENNE DE SIGNAL DE RÉFÉRENCE POUR CANAL DE COMMANDE DE LIAISON DESCENDANTE DANS UN SYSTÈME DE COMMUNICATIONS SANS FIL
(KO) 무선 통신 시스템에서 하향링크 제어 채널을 위한 참조 신호 안테나 포트 결정 방법 및 이를 위한 장치
Abstract: front page image
(EN)The present invention relates to a method of transmitting a downlink control channel including one or more control channel elements to a terminal by a base station in a wireless communication system. In particular, the method includes: allocating an antenna port of a demodulation-reference signal (DM-RS) to the one or more control channel elements that configure the downlink control channel; and transmitting the downlink control channel to the terminal by using the DM-RS of the allocated antenna port, wherein the antenna port of the DM-RS is determined on the basis of the number of control channel elements per resource block.
(FR)La présente invention concerne un procédé de transmission d'un canal de commande de liaison descendante comportant un ou des élément(s) de canal de commande vers un terminal par une station de base dans un système de communications sans fil. En particulier, le procédé comprend les étapes suivantes : l'allocation d'un port d'antenne d'un signal de référence de démodulation (DM-RS) à un ou des élément(s) de canal de commande qui configurent le canal de commande de liaison descendante ; et la transmission du canal de commande de liaison descendante au terminal au moyen du signal DM-RS du port d'antenne alloué, le port d'antenne du signal DM-RS étant déterminé sur la base du nombre d'éléments de canal de commande par bloc de ressources.
(KO)본 출원에서는 무선 통신 시스템에서 하나 이상의 제어 채널 요소로 구성된 하향링크 제어 채널을 기지국이 단말로 송신하는 방법이 개시된다. 구체적으로, 상기 방법은, 상기 하향링크 제어 채널을 구성하는 하나 이상의 제어 채널 요소에 대하여 DM-RS (Demodulation-Reference Signal)의 안테나 포트를 할당하는 단계; 및 상기 할당된 안테나 포트의 DM-RS를 이용하여, 상기 단말로 상기 하향링크 제어 채널을 송신하는 단계를 포함하며, 상기 DM-RS의 안테나 포트는, 자원 블록 당 제어 채널 요소의 개수에 기반하여 결정되는 것을 특징으로 한다.
