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.

本发明公开了一种时分双工系统中发送数据的方法、装置及系统，用以解决现有技术中邻近小区间的下行数据对上行数据产生干扰的问题；该方法包括将全小区覆盖信道或大功率发射信道映射到传输帧中下行时隙的OFDM符号上，并且所述传输帧中的保护间隔与所述OFDM符号在时域上间隔未映射全小区覆盖信道和大功率发射信道中任一信道的OFDM符号；将上行控制信道映射到所述传输帧中上行时隙的OFDM符号上，并且所述保护间隔与映射上行控制信道的OFDM符号在时域上间隔未映射上行控制信道的OFDM符号；发送所述传输帧的OFDM符号；采用本发明可以避免相邻小区间的下行数据和上行数据之间的干扰。

The simplest, the domain name that I am passed by K, when doing client business, also conveniently is added to his, after passing a many month, domain name and those who restore home page collect, and can SITE arrives, I did not become friendship link during this, also did not undertake referring to Baidu, of course these I said everybody to be able to be denied possibly one by one, because after all king mother-in-law sells melon, blow one's own trumpet.

最简单的，一个我被K过的域名，在做客户业务的时候，也顺手给自己的加上去了，经过一个多月后，域名以及恢复首页的收录，并且可以SITE到，这期间我并没有做友情链接，也没有向百度进行提交，当然这些我说了大家可能都会一一否认，因为毕竟王婆卖瓜，自卖自夸。
