The invention discloses a data transmitting method, a device and a system in a time division duplex system, which is used to solve the problem in the prior art that downlink data among adjacent cells interfere to uplink data; the method comprises that: a blanket channel of a whole cell or a high-power transmit channel is mapped to OFDM symbols of a downlink time slot in a transmit frame, a guard interval in the transmit frame and the OFDM symbol on a time domain space OFDM symbols which are not mapped to any of the blank channel of the whole cell and the high-power transmit channel; an uplink control channel is mapped to OFDM symbols of an uplink time slot in the transmit frame, the guard interval and the OFDM symbols for mapping the uplink control channel on the time domain space OFDM symbols which are not mapped to uplink control channel; the OFDM symbols of the transmit frame are transmitted; the invention is adopted to avoid the interference between the downlink data and the uplink data among the adjacent cells.

The invention relates to an external synchronous TD-SCDMA cover network system, which comprises a main coverer and at least one driven coverer forming the cover network system; said main coverer, via synchronizing the TD-SCDMA descending signal of descending chain, outputs descending-ascending switch control signal to the main coverer, to obtain frame synchronization; sending the synchronous instruct signal to the driven coverer; obtaining the frame synchronization at the driven coverer, via external synchronous instruction signal, to complete the normal ascending-descending time slit switch.

本发明外同步TD-SCDMA覆盖网络系统，包括组成覆盖网络系统的主覆盖端和至少一个从覆盖端，所述主覆盖端通过对下行链路中的TD-SCDMA下行信号进行同步处理，向主覆盖端输出上下行切换控制信号，获得帧同步；并将同步指示信号发送至从覆盖端，从覆盖端根据外同步指示信号进一步获得帧同步，从而完成整个覆盖网络系统的正常上下行时隙切换。

He put on first the aerial breeze, then threw over himself light as a flaming mantle, and over this light a covering of water; he surrounded himself with gusts of wind, took light as his lance and shield, and cast himself downward toward the line of danger.

他提出的第一个空中的微风，然后扔在自己轻如燃烧的地幔，并在此轻覆盖的水；他包围自己的阵风风力，光了他的长矛和盾牌，并自诩为对向下行的危险。

In anFDD wireless system, the duplex spacing between uplink and downlink islarger than the coherence bandwidth of the mobile radio channel, thus theuplink and the downlink small-scale fading is uncorrelated. Moreover, thearray response is correlated with the frequency of the signal carrier. So it isimpossible to resue the uplink weights for downlink beamforming. As aresult, the application of smart antenna for the downlink is a difficult problem.

在频分双工系统中，由于上、下行载波的频率差大于相干频带，上、下行信道衰落是不相关的，而且阵列响应也与信号的载波频率有关，因此，上行信道不能直接用来估计下行信道，故智能天线应用于下行链路是一个难点。
