查询词典 transmit-receive

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。

With this technology the multimedia information can be displayed while it is being downloaded, so that the users do not have to waste their time when downloading, and there will be a redically reduced need in the system memeory capacity, and then the multicast technology of the streaming media transmit technology has more advantage, it has the functions which can transmit a stream for a group of client without any delay or broadcast storm. Therefore it can inprove the availability of the network system.

流媒体以边下载边播放的特点，不但除去了用户漫长的下载等待痛苦，而且极大地降低了对系统存储容量的需求，同时流媒体传输技术中的组播技术具有更大的优势，它能让媒体服务器同时向多个客户端发送连续数据流而不产生延时，而且又不会产生广播风暴，极大地提高了网络利用率。
