Title
(EN) SYSTEM AND METHOD FOR SHARING A CONTROL CHANNEL FOR CARRIER AGGREGATION
(FR) SYSTÈME ET PROCÉDÉ PERMETTANT DE PARTAGER UN CANAL DE COMMANDE POUR L'AGRÉGATION DE PORTEUSES
Abstract
(EN)
A method for processing a control channel at a user agent (UA) to identify at least one of an uplink and a downlink resource allocated by a resource grant within a multi-carrier communication system wherein resource grants are specified by control channel element (CCE) subset candidates wherein the carriers used for data transmission and reception are configured carriers, the method comprising the steps of receiving activation signals specifying active and deactivated carriers from among the configured carriers, for active carriers (i) identifying a number of CCE subset candidates to decode and (ii) decoding up to the identified number of CCE subset candidates in an attempt to identify the resource grant; and for deactivated carriers, ignoring CCE subset candidates associated with the deactivated carriers.
(FR)
L'invention concerne un procédé permettant de traiter un canal de commande à l'emplacement d'un agent utilisateur (UA) afin d'identifier une ressource de liaison montante et/ou une ressource de liaison descendante attribuées grâce à une affectation de ressources dans un système de communication à porteuses multiples, les affectations de ressources étant indiquées par les candidats d'un sous-ensemble d'éléments de canal de commande (CCE), et les porteuses utilisées pour l'émission et la réception de données étant des porteuses configurées. Ledit procédé consiste : à recevoir des signaux d'activation indiquant les porteuses actives et les porteuses désactivées parmi les porteuses configurées; pour les porteuses actives, (i) à identifier un nombre de candidats du sous-ensemble de CCE qui doivent être décodés, et (ii) à décoder au maximum le nombre de candidats du sous-ensemble de CCE qui ont été identifiés, lors d'un essai d'identification de l'affectation de ressources; et pour les porteuses désactivées, à ignorer les candidats du sous-ensemble de CCE associés à ces porteuses désactivées.
