Abstract
(EN)
The present invention relates to a wireless communication system. In detail, the present invention is a method in which user equipment for which a plurality of cells is constituted receives control information in a carrier aggregation-based wireless communication system, and an apparatus for the method. The method comprises: a step of receiving, through a first cell, uplink resource allocation information for a second cell; a step of transmitting an uplink signal on the second cell using the uplink resource allocation information; and a step of receiving response information to the uplink signal. The response information is received via a specific cell rather than the first cell when the uplink signal is transmitted by a random access process, and the response information is received via the first cell when the uplink signal is transmitted by a non-random access process.

La présente invention se rapporte à un système de communication sans fil. Plus en détail, elle a trait à un procédé au cours duquel un équipement utilisateur pour lequel une pluralité de cellules est constituée reçoit des informations de commande dans un système de communication sans fil basé sur l'agrégation de porteuses, et à un appareil destiné à ce procédé. Ledit procédé comprend : la réception, par l'intermédiaire d'une première cellule, d'informations d'attribution de ressources de liaison montante pour une seconde cellule ; la transmission d'un signal montant sur la seconde cellule au moyen desdites informations d'attribution de ressources de liaison montante ; et la réception d'informations de réponse au signal montant. Ces informations de réponse sont reçues par le biais d'une cellule spécifique et non de la première cellule lorsque le signal montant est transmis grâce à un processus d'accès aléatoire, et les informations de réponse sont reçues par le biais de la première cellule lorsque le signal montant est transmis grâce à un processus d'accès non aléatoire.
