METHOD, SYSTEM AND DEVICE FOR TRANSMITTING DATA IN TIME DIVISION DUPLEX (TDD) WIRELESS FRAME

摘要

The embodiments of the present invention relate to the technical field of wireless communication, especially to a method, system and device for transmitting data in Time Division Duplex(TDD) wireless frame, and is used to solve the problem of prior art that the uplink and downlink sub-frame configuration in TDD cell can not adapt to service demand changes. The method for transmitting data in TDD wireless frame provided by the embodiments of the present invention comprises: a network side determines uplink and downlink sub-frame configuration information of an evolutional TDD user device, and transmits the uplink and downlink sub-frame configuration information to the evolution TDD user device via user private high-layer signaling; said network side transmits data via a TDD wireless frame. The present invention configures TDD uplink and downlink sub-frame for the user device using the high-layer signaling, thus ensuring reducing variation period and adapting to service demand changes; moreover avoiding the need for all the user devices in the cell to frequently re-read system information and reducing power consumption of the user device.
