The method of transmitting data in a radio frame Tdd, systems and devices

The embodiment of the invention relates to the technical field of radio communication, in particular to a method, a system and equipment for transmitting data in a time division duplex (TDD) radio frame. The method, the system and the equipment are used for solving the problem that uplink and downlink sub-frame configuration of a TDD cell cannot adapt to the change of service requirements in the prior art. The method for transmitting the data in the TDD radio frame in the embodiment comprises that: a network determines uplink and downlink sub-frame configuration information of evolved TDD user equipment, and sends the uplink and downlink sub-frame configuration information to the evolved TDD user equipment through user dedicated high-layer signaling; and the network transmits the data through the TDD radio frame. Because TDD uplink and downlink sub-frames are configured for the user equipment through the high-layer signaling in the embodiment, the change period is shortened, and the change of the service requirements can be adapted; and all user equipment in the cell do not need to frequently re-read system message, so power consumption of the user equipment is saved.
