Abstract: front page image
(EN)The present invention relates to a wireless access system supporting carrier aggregation and carrier aggregation technology, and discloses methods for effectively searching control signals for a plurality of cells and apparatuses supporting same. In an embodiment of the present invention, a method for searching control signals in a wireless access system supporting multiple carrier aggregation (CA) and cross carrier scheduling may comprise the steps of: calculating the start point of a reference search space in an expanded search space; calculating start points of the next search spaces which are spaced apart from the reference search space by a predetermined offset value; and performing blind decoding on the reference search space and subsequent search spaces to search control signals from a base station.
(FR)La présente invention concerne un système d'accès sans fil supportant l'agrégation de porteuse et la technologie d'agrégation de porteuse, ainsi que des procédés de recherche effective de signaux de commande pour une pluralité de cellules et appareils la supportant. Dans un mode de réalisation de la présente invention, un procédé de recherche de signaux de commande dans un système d'accès sans fil supportant l'agrégation de porteuses multiples (CA) et la planification de porteuses transverses peut comprendre les étapes suivantes : calcul du point de départ d'un espace de recherche de référence dans un espace de recherche étendu ; calcul des points de départ des espaces de recherche suivants, espacés de l'espace de recherche de référence par une valeur de décalage prédéterminée ; et réalisation d'un décodage aveugle sur l'espace de recherche de référence et sur les espaces de recherche suivants pour rechercher des signaux de commande provenant d'une station de base.
(KO)본 발명은 반송파 집성(Carrier Aggregation) 기술을 지원하는 무선접속 시스템에 관한 것으로, 다수의 셀에 대한 제어신호를 효과적으로 검색할 수 있는 방법들 및 이를 지원하는 장치들을 개시한다. 본 발명의 일 실시예로서 다중 반송파 집성(CA) 및 크로스 캐리어 스케줄링을 지원하는 무선 접속 시스템에서 제어신호를 검색하는 방법은, 확장된 서치 스페이스에서 기준 서치 스페이스의 시작점을 산출하는 단계와 기준 서치 스페이스로부터 소정의 오프셋 값을 갖는 위치에 있는 다음 서치 스페이스들의 시작점을 산출하는 단계와 기준 서치 스페이스 및 다음 서치 스페이스들에서 블라인드 디코딩을 수행하여 기지국으로부터 제어신호를 검색하는 단계를 포함할 수 있다.
