摘　　要：TD-SCDMA移动通信系统在数据业务方面引入了高速下行分组接入(HSDPA)新技术,用户下行理论数据吞吐量可以达到每时隙560kb/s。由于TD-SCDMA技术可以采用灵活的上下行时隙配比,同时考虑到数据业务多发生在室内环境中,因此在组网方面,可以考虑室内外采用不同的时隙配比,即室内2:4、室外3:3分配时隙,但是不可避免会造成同频组网下室内外时隙的互干扰,为此文章作者进行了TD-SCDMA室内外不同时隙配比互干扰测试,结合本次测试,对TD-SCDMA系统室内外不同时隙配比同频互干扰测试的理论进行分析研究,提出了TD-SCDMA室内外不同时隙配比同频互干扰条件下的组网推荐策略。The High-Speed Downlink Packet Access （HSDPA） technology is employed in the TD-SCDMA mobile communication system. Theoretically, the HSDPA peak data rate per time slot available in the terminals can be 560 kb/s. Since the data services are often occurred indoors, so the flexible time slot allocation between uplink and downlink is applied in TD-SCDMA network strategy, i.e. TS1 and TS2 are uplink time slots and TS3, TS4, TS5 and TS6 are downlink time slots in the indoor cell; and symmetry time slots are for the outdoor cell. In the intra-frequency cell network, it can cause the intra-frequency interference between the cells. So the research on the intra-frequency crossed time slots interference is done and the suggestions on the intra-frequency crossed time slots network strategy are proposed in the paper.
