Abstract:
(EN) Disclosed in the embodiments of the present invention are a method, a device, and a system for transmitting downlink control information, which belong to the technical field of wireless communications. The method comprises: a base station determining uplink scheduling downlink control information (DCI), to which a terminal corresponds, and determining a transmission time interval (TTI) to transmit the uplink scheduling DCI; the base station sending, within the TTI, the uplink scheduling DCI to the terminal, if a time frequency region, which is indicated by downlink scheduling DCI that is allocated by the base station to the terminal, is included within the TTI, a time frequency resource of the uplink scheduling DCI being situated in the time frequency region indicated by the downlink scheduling DCI. The present invention can reduce the waste of time frequency resources.
(FR) Les modes de réalisation de la présente invention concernent un procédé, un dispositif, et un système de transmission d'informations de commande de liaison montante, appartenant au domaine des communications sans fil. Le procédé comprend les étapes suivantes : une station de base détermine des informations de commande de liaison descendante (DCI) de programmation de liaison montante, auxquelles un terminal correspond, et détermine un intervalle de temps de transmission (TTI) pour transmettre les DCI de programmation de liaison montante ; durant le TTI, la station de base envoie les DCI de programmation de liaison montante au terminal, si une région temps-fréquence, qui est indiquée par des DCI de programmation de liaison descendante attribuées par la station de base au terminal, est incluse dans le TTI, une ressource temps-fréquence des DCI de programmation de liaison montante étant située dans la région temps-fréquence indiquée par les DCI de programmation de liaison descendante. La présente invention permet de réduire le gaspillage de ressources temps-fréquence.
(ZH) 本发明实施例公开了一种下行控制信息的传输方法、装置和系统,属于无线通信技术领域。所述方法包括:基站确定终端对应的上行调度下行控制信息DCI,并确定传输所述上行调度DCI的传输时间间隔TTI;所述基站在所述TTI内,向所述终端发送所述上行调度DCI,其中,如果所述TTI内包括所述基站为所述终端分配的下行调度DCI指示的时频区域,则所述上行调度DCI的时频资源位于所述下行调度DCI指示的时频区域内。采用本发明,可以减少时频资源的浪费。
