Abstract:
(EN) The present invention relates to a method for receiving a downlink control channel by a terminal in a wireless communication system. Particularly, the method may comprise the steps of: receiving, through a higher layer, information on a resource element group (REG) bundle size and information related to a size of a matrix for interleaving multiple REGs constituting at least one control channel element (CCE); determining the matrix for interleaving the multiple REGs, on the basis of the information related to the size of the matrix and the information on the REG bundle size; interleaving the multiple REGs, bundled into one or more REG bundles according to the REG bundle size, using the matrix; and receiving a downlink control channel on the basis of the interleaved multiple REGs.
(FR) La présente invention concerne un procédé de réception d'un canal de commande de liaison descendante par un terminal dans un système de communication sans fil. En particulier, le procédé peut comprendre les étapes suivantes : recevoir, par l'intermédiaire d'une couche supérieure, des informations sur une taille de regroupement de groupes d'éléments de ressources (REG) et des informations concernant une taille d'une matrice d'entrelacement de multiples REG constituant au moins un élément de canal de commande (CCE) ; déterminer la matrice d'entrelacement des multiples REG, en fonction des informations concernant la taille de la matrice et des informations sur la taille du regroupement de REG ; entrelacer les multiples REG, regroupés en un ou plusieurs regroupements de REG selon la taille de regroupement de REG, grâce à la matrice ; et recevoir un canal de commande de liaison descendante en fonction des multiples REG entrelacés.
(KO) 본 발명은, 무선 통신 시스템에서, 단말이 하향링크 제어 채널을 수신하는 방법에 대한 것이다. 특히, 상기 방법은, 상위 계층을 통해, 자원 요소 그룹(Resource Element Group; REG) 번들 크기에 대한 정보 및, 적어도 하나의 제어 채널 요소(Control Channel Element; CCE)를 구성하는 복수의 REG들을 인터리빙하기 위한 행렬의 크기와 관련된 정보를 수신하는 단계; 상기 행렬의 크기와 관련된 정보 및 상기 REG 번들 크기에 대한 정보를 기반으로, 상기 복수의 REG들을 인터리빙하기 위한 행렬을 결정하는 단계; 상기 행렬을 이용하여, 상기 REG 번들 크기에 따라 하나 이상의 REG 번들로 번들링된 상기 복수의 REG들을 인터리빙하는 단계; 및 상기 인터리빙된 복수의 REG들을 기반으로, 상기 하향링크 제어 채널을 수신하는 단계를 포함할 수 있다.
