(FR) PROCÉDÉ DE LIMITATION DE BROUILLAGE INTERCELLULAIRE DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET DISPOSITIF CORRESPONDANT
(KO) 무선 통신 시스템에서 셀 간 간섭을 완화하는 방법 및 이를 위한 장치
Abstract: front page image
(EN)The present application provides a method for allowing a cell to remove inter-cell interference in a wireless communication system. Specifically, said method comprises the steps of: receiving, from neighboring cells, time resource interference information on a first subframe type and a second subframe type; receiving, from said neighboring cells, first frequency resource interference information corresponding to said first subframe type and second frequency resource interference information corresponding to said second subframe type; and performing downlink communication and uplink communication by using said first frequency resource interference information, said second frequency resource interference information, and said time resource interference information.
(FR)La présente demande porte sur un procédé servant à permettre à une cellule de supprimer un brouillage intercellulaire dans un système de communication sans fil. Spécifiquement, ledit procédé comprend les étapes consistant à : recevoir, en provenance de cellules voisines, des informations de brouillage de ressource temporelle sur un premier type de sous-trame et un second type de sous-trame ; recevoir, en provenance desdites cellules voisines, des premières informations de brouillage de ressource fréquentielle correspondant audit premier type de sous-trame et des secondes informations de brouillage de ressource fréquentielle correspondant audit second type de sous-trame ; et effectuer une communication en liaison descendante et une communication en liaison montante par utilisation desdites premières informations de brouillage de ressource fréquentielle, desdites secondes informations de brouillage de ressource fréquentielle et desdites informations de brouillage de ressource temporelle.
(KO)본 출원에서는 무선 통신 시스템에서 셀이 셀 간 간섭을 제거하는 방법을 개시한다. 구체적으로, 상기 방법은, 제 1 서브프레임 타입 및 제 2 서브프레임 타입에 관한, 시간 자원 간섭 정보를 인접 셀로부터 수신하는 단계; 상기 제 1 서브프레임 타입에 대응하는 제 1 주파수 자원 간섭 정보와 상기 제 2 서브프레임 타입에 대응하는 제 2 주파수 자원 간섭 정보를 상기 인접 셀로부터 수신하는 단계; 및 상기 제 1 주파수 자원 간섭 정보, 상기 제 2 주파수 자원 간섭 정보 및 상기 시간 자원 간섭 정보를 이용하여, 하향링크 통신 및 상향링크 통신을 수행하는 단계를 포함하는 것을 특징으로 한다.
