Title (EN) METHOD FOR TRANSMITTING OR RECEIVING DOWNLINK CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR SAME
(FR) PROCÉDÉ D’ÉMISSION OU DE RÉCEPTION D'INFORMATIONS DE COMMANDE DE LIAISON DESCENDANTE DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET APPAREIL CORRESPONDANT
(KO) 무선 통신 시스템에서 하향링크 제어 정보를 송신 또는 수신하는 방법 및 이를 위한 장치
Abstract: front page image
(EN) A method for receiving downlink control information by a terminal in a wireless communication system according to one embodiment of the present invention may comprise the steps of: receiving control channel element (CCE) configuration information from a base station; determining multiple control channel candidates, each of which has one or more CCEs, on the basis of the CCE configuration information; and blind-detecting downlink control information through the multiple control channel candidates, wherein: each of the one or more CCEs comprises multiple resource element groups (REGs), and the number of data resource elements (REs) for carrying the downlink control information is independently determined for each REG; and the CCE configuration information indicates whether each CCE has a fixed number of REGs or a fixed number of data REs.
(FR) Selon un mode de réalisation, la présente invention concerne un procédé de réception d'informations de commande de liaison descendante par un terminal dans un système de communication sans fil qui peut comprendre les étapes consistant à : recevoir des informations de configuration d'éléments de canal de commande (CCE) en provenance d'une station de base ; déterminer de multiples canaux de commande candidats, dont chacun comprend un ou plusieurs CCE, sur la base des informations de configuration de CCE ; et détecter à l'aveugle des informations de commande de liaison descendante dans les multiples canaux de commande candidats, chacun du ou des CCE comprenant de multiples groupes d'éléments de ressource (REG), et le nombre d'éléments de ressource (RE) de données servant à transporter les informations de commande de liaison descendante étant déterminé indépendamment pour chaque REG ; et les informations de configuration de CCE indiquant si chaque CCE comprend un nombre fixe de REG ou un nombre fixe de RE de données.
(KO) 본 발명의 일 실시예에 따른 무선 통신 시스템에서 단말이 하향링크 제어 정보를 수신하는 방법은, 기지국으로부터 CCE (control channel element) 설정 정보를 수신하는 단계; 각각이 하나 또는 둘 이상의 CCE들을 갖는 복수의 제어 채널 후보들을 상기 CCE 설정 정보에 기반하여 결정하는 단계; 및 상기 복수의 제어 채널 후보들을 통해서 하향링크 제어 정보를 블라인드 검출하는 단계를 포함하고, 상기 하나 또는 둘 이상의 CCE들 각각은 복수의 REG (resource element group)들을 포함하되, 상기 하향링크 제어 정보를 나르기 위한 데이터 RE(resource element)들의 개수는 각 REG 마다 독립적으로 결정되고, 상기 CCE 설정 정보는, 각 CCE가 고정된 개수의 REG들을 갖는지 아니면 고정된 개수의 데이터 RE들을 갖는지 여부를 지시할 수 있다.
