Abstract: Radio communication method and device with an alterable TTI are provided. The method includes: blindly detecting a primary physical downlink link control channel to acquire first downlink control information which includes configuration information and an exit frame number of a first target TTI; scheduling the first target TTI based on the first downlink control information, and performing data transmission with a base station; and when a frame number of transmitted data exceeds the exit frame number, blindly detecting the primary physical downlink link control channel to schedule a second target TTI indicated by the primary physical downlink link control channel. Solutions in embodiments of the present disclosure may enable to use various TTI simply and efficiently in radio communication, and are particularly adaptive to the feature of TCP service.

Abstract: A UE and a data transmission method thereof are provided. The method includes: acquiring configuration information of a first shortened TTI sent by a base station; blindly detecting a predetermined physical downlink link control channel with a period of the first shortened TTI, until primary DCI corresponding to the UE is acquired; determining secondary DCI corresponding to the UE based on the acquired primary DCI; and performing data transmission with the base station in a second shortened TTI scheduled by the secondary DCI. Flexibility of application of a shortened TTI may be improved, and resources may be saved.
