요약서
(EN)
A method for allocating PDCCH channel, includes: dividing the physical downlink control channel (PDCCH) into two sets according to a scheduled PDCCH format; setting a control channel element (CCE) from the allocable control channel elements as a constant beginning CCE for each set; allocating CCE for each set of PDCCH sets, beginning respectively from the said constant beginning CCE. The embodiment of the invention also provides an indicating method for allocating ACK/NACK channel, a device for allocating PDCCH, a device for sending ACK/NACK channel, a device for receiving ACK/NACK channel, a base station and a terminal using said device for sending ACK/NACK channel and said device for receiving ACK/NACK channel. With this embodiment, it is practical to indicate recessively the allocation of ACK/NACK channel, and to reduce the waste of communication channel resources.
(FR)
L'invention concerne un procédé d'allocation d'un canal PDCCH. Le procédé consiste à : diviser le canal de commande de liaison descendante physique (PDCCH) en deux ensembles conformément à un format PDCCH planifié ; définir un élément de canal de commande (CCE) parmi les éléments de canal de commande allouables en tant que CCE de début constant pour chaque ensemble ; allouer un CCE pour chaque ensemble des ensembles PDCCH, en commençant respectivement par ledit CCE de début constant. Le mode de réalisation de l'invention concerne aussi un procédé d'indication pour l'allocation d'un canal d'acquittement/non acquittement (ACK/NACK), un dispositif d'allocation d'un PDCCH, un dispositif pour envoyer un canal ACK/NACK, un dispositif pour recevoir un canal ACK/NACK, une station de base et un terminal utilisant le dispositif pour envoyer un canal ACK/NACK et le dispositif pour recevoir un canal ACK/NACK. Ce mode de réalisation permet d'indiquer de façon rétrograde l'allocation de canal ACK/NACK et de réduire le gaspillage de ressources de canaux de communication.
