Abstract: front page image
(EN)A data retransmission method, base station, terminal, and wireless communication system are provided by the present invention. Said data retransmission method comprises: a base station sets Hybrid-Automatic-Repeat-Request (HARQ) Maximum-Retransmission-Interval based on a retransmission parameter (S302), wherein said retransmission parameter includes frame structure of the data frame and/or Maximum-Retransmission-Times; said base station determines a control channel signaling transmitted on the control channel based on said HARQ Maximum-Retransmission-Interval (S304), wherein said control channel signaling includes retransmission interval indication information; said base station transmits said retransmission parameter and said control channel signaling to a terminal (S306); said terminal determines said HARQ Maximum-Retransmission-Interval based on said retransmission parameter and said control channel signaling (S308); said terminal and said base station retransmit data packets based on said HARQ Maximum-Retransmission-Interval (S310). By use of the present invention, the base station and the terminal could know the HARQ Maximum-Retransmission-Interval merely by one signaling transmission while retransmitting data, so the signaling overhead can be effectively saved.
(FR)La présente invention porte sur un procédé de retransmission de données, une station de base, un terminal et un système de communication sans fil. Ledit procédé de retransmission de données comprend les opérations suivantes : une station de base règle un intervalle de retransmission maximal de requête de répétition automatique hybride (HARQ) sur la base d'un paramètre de retransmission (S302), ledit paramètre de retransmission comprenant une structure de trame de la trame de données et/ou des temps de retransmission maximaux ; ladite station de base détermine une signalisation de canal de commande transmise sur le canal de commande sur la base dudit intervalle de retransmission maximal HARQ (S304), ladite signalisation de canal de commande comprenant des informations d'indication d'intervalle de retransmission ; ladite station de base envoie ledit paramètre de retransmission et ladite signalisation de canal de commande à un terminal (S306) ; ledit terminal détermine ledit intervalle de retransmission maximal HARQ sur la base dudit paramètre de retransmission et de ladite signalisation de canal de commande (S308) ; ledit terminal et ladite station de base retransmettent des paquets de données sur la base dudit intervalle de retransmission maximal HARQ (S310). Par utilisation de la présente invention, la station de base et le terminal peuvent connaître l'intervalle de retransmission maximal HARQ simplement par une seule transmission de signalisation pendant une retransmission de données, ce qui permet de réduire efficacement le surdébit de signalisation.
