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。

In general, there is lots of geographic information on it. Point symbols, linear symbols, area symbols and texts counterchange on topographic map. Description of Relations among graphs is very difficult. Besides, there is defectiveness in scanning and deformation of map.

从总体上看，地形图承载了大量的地理信息，各种点状符号、线状符号、面状符号、文字注记在空间上纵横交错、相互叠置，反映在地形图上的是图形目标间的关系难以描述，再加扫描技术的不完善等因素，这给图象的分割和要素的识别以及拓扑信息的提取带来了很大的困难。

This essay aims to probe into the creation and identification of cultural symbols. Firstly, the relationship between development and symbolism of architectural forms in Taiwan through out different eras are sorted. Secondly, how the operation of school architectures has changed from the iconic form into the "space" analogical form is discussed through the study of Tannan Elementary School, which was built up in the mountain of Nantou after the 921 Earthquake. In the end of the essay, the unique architectural operation of another aboriginal school, Minho Elementary School, has demonstrated that the development of school architectures is still dominated by the cultural symbol of "political correctness" in Taiwan after the 921 Earthquake.

本文以「文化象徵」 Cultural Symbols 的创造与辨识为主题，先整理各个时期台湾建筑形式的发展与象徵性的紧密关系；然后以921地震后，在南投山村间出现的一间原住民小学 aboriginal elementary Tannan Elementary School 为研究对象，说明台湾学校建筑已从符号 iconic 象徵性的浅层操作开始进入「空间类型」类比化的建筑操作；文末另以一间原住民小学 Minho Elementary School 的回异操作方法，印证台湾在921地震后的这波学校建筑的发展，仍然被「政治正确」的文化表徵所支配。
