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.
Claims22
A data transmission method of User Equipment (UE), comprising:
- acquiring configuration information of a first shortened Transmission Time Interval (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 Downlink Control Information (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.
A User Equipment (UE), comprising:
- a configuration acquiring circuitry, configured to acquire configuration information of a first shortened Transmission Time Interval (TTI) sent by a base station;
- a blindly detecting circuitry, configured to blindly detect a predetermined physical downlink link control channel with a period of the first shortened TTI, until primary Downlink Control Information (DCI) corresponding to the UE is acquired;
- a secondary DCI determining circuitry, configured to determine secondary DCI corresponding to the UE based on the acquired primary DCI;
- and
- a transmission circuitry, configured to perform data transmission with the base station in a second shortened TTI scheduled by the secondary DCI.
