Title
(EN) TRANSMISSION METHOD AND DEVICE FOR CONTROL INFORMATION
(FR) PROCÉDÉ DE TRANSMISSION ET DISPOSITIF POUR INFORMATIONS DE COMMANDE
(ZH) 一种控制信息的传输方法和装置
Abstract
(EN) A transmission, base station, and user equipment for control information. The transmission method comprises: a base station transmits first control information on a second carrier, where the first control information is for use by the base station in transmitting data on a first carrier on the basis of the first control information; the base station transmits the data on the first carrier on the basis of the first control information, where the length of time of the transmission time interval of the first carrier is less than the length of time of the transmission time interval of the second carrier. With the base station transmitting the data on the first carrier and transmitting the first control information on the second carrier, because the frequency of the second carrier is lower than the frequency of the first carrier, large-scale losses on the second carrier are less than large-scale losses on the first carrier, as such, the reliability in the transmission of the first control information is increased by transmitting the first control information on the second carrier.
(FR) L'invention concerne une transmission, une station de base et un équipement d'utilisateur pour des informations de commande. Le procédé de transmission comprend : la transmission par une station de base de premières informations de commande sur une seconde porteuse, les premières informations de commande étant destinées à être utilisées par la station de base dans la transmission de données sur une première porteuse en fonction des premières informations de commande ; la transmission par la station de base des données sur la première porteuse en fonction des premières informations de commande, la durée de l'intervalle de temps de transmission de la première porteuse étant inférieure à la durée de l'intervalle de temps de transmission de la seconde porteuse. Grâce à la transmission par la station de base des données sur la première porteuse et à la transmission des premières informations de commande sur la seconde porteuse, étant donné que la fréquence de la seconde porteuse est inférieure à la fréquence de la première porteuse, des pertes à grande échelle sur la seconde porteuse sont inférieures à celles sur la première porteuse, et ainsi, la fiabilité dans la transmission des premières informations de commande est augmentée par la transmission des premières informations de commande sur la seconde porteuse.
(ZH) 一种控制信息的传输方法,基站和用户设备。其中所述传输方法包括基站在第二载波上发送第一控制信息,所述第一控制信息用于所述基站根据所述第一控制信息在第一载波上发送数据;所述基站根据所述第一控制信息在第一载波上发送所述数据;其中,所述第一载波的传输时间间隔的时间长度小于所述第二载波的传输时间间隔的时间长度。基站在第一载波上发送数据,而在第二载波上发送第一控制信息,由于第二载波的频率小于第一载波的频率,因此,第二载波上的大尺度损耗小于第一载波上的大尺度损耗,从而将第一控制信息放在第二载波上发送提高了第一控制信息传输的可靠性。
