Embodiment Construction

[0037] In the embodiment of the present invention, the network side sends uplink and downlink subframe configuration information to the evolved TDD user equipment through user-specific high-level signaling; the evolved TDD user equipment receives uplink and downlink subframes from the network side through user-specific high-level signaling Configuration information for TDD wireless frame transmission data. Since the implementation of the present invention configures TDD uplink and downlink subframes for user equipment through high-level signaling, the change cycle is shortened, and it can adapt to changes in service requirements; and it is not necessary for all user equipment in the cell to frequently re-read system messages, saving users The power consumption of the device.

[0038] Wherein, the evolved TDD user equipment is user equipment of LTE Rel (release)-11 and later versions. The TDD uplink and downlink subframe configuration corresponding to the uplink and downlink s...

Abstract

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.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, system and equipment for transmitting data in a TDD wireless frame. Background technique [0002] For the basic duplex mode adopted by the cellular system, the TDD (Time division duplex) mode means that the uplink and downlink use the same working frequency band, and the uplink and downlink signals are transmitted at different time intervals. There is a guard interval (Guard Period, GP) between them; FDD (Frequency division duplex, frequency division duplex) mode means that the uplink and downlink use different working frequency bands, and the uplink and downlink signals can be carried out on different frequency carriers at the same time There is a guard bandwidth (Guard Band, GB) between the uplink and downlink. [0003] The frame structure of the LTE (Long Term Evolution, long-term evolution) TDD system is slightly more complicated, such as fi...
