Title (EN) METHOD FOR TRANSMITTING HARQ-ACK
(FR) PROCÉDÉ DE TRANSMISSION HARQ-ACK
Abstract:
(EN) A method for transmitting HARQ-ACK, for N downlink component carriers and 1 uplink component carrier, transmitting HARQ-ACK information of N downlink component carriers in HARQ-ACK channel of an uplink component carrier, one of N downlink component carrier being a reference downlink component carrier, comprising steps of: on consecutive HARQ-ACK channels beginning with the first of N downlink componet carrier, transmitting HARQ-ACK for CCE in the reference downlink component carrier; and on consecutive HARQ-ACK channels beginning with N(I)PUCCH, N(I)PUCCH + f(k) transmitting HARQ-ACK for CCE in other downlink component carriers, wherein k is information related to downlink component carrier. The method of this invention can reduce the HARQ-ACK channel overhead of uplink component carrier and the limitations on the flexibility of the scheduler in the base station.
(FR) L'invention concerne un procédé de transmission HARQ-ACK, pour N porteuses de composante en liaison descendante et 1 porteuse de composante en liaison montante, permettant de transmettre des informations HARQ-ACK de N porteuses de composante en liaison descendante dans un canal HARQ-ACK d'une porteuse de composante en liaison montante, une des N porteuses de composante en liaison descendante étant une porteuse de composante en liaison descendante de référence. Le procédé comprend les étapes consistant à : sur des canaux HARQ-ACK consécutifs, en commençant avec la première des N porteuses de composante en liaison descendante, transmettre HARQ-ACK pour CCE dans la porteuse de composante en liaison descendante de référence; et sur des canaux HARQ-ACK consécutifs en commençant avec N(I)PUCCH, N(I)PUCCH + f(k) transmettre HARQ-ACK pour CCE dans d'autres porteuses de composante en liaison descendante, où k constitue les informations associées à la porteuse de composante en liaison descendante. Le procédé de la présente invention peut réduire le surdébit de canal HARQ-ACK de porteuse de composante en liaison montante et les limitations de flexibilité du programmateur dans la station de base.
