Abstract: The High Speed Downlink Packet Access (HSDPA ) technology is employed for the data service in the Time Division Synchronous Code Division Multiple Access (TD-SCDMA ) mobile communication system. Theoretically, the HSDPA peak data throughput per Time Slot (TS ) available in the terminals reaches 560 kb/s. Since the data service often occurs indoors, flexible TS allocation between uplink and downlink is applied in TD-SCDMA networking. That is, TS1 and TS2 are uplink time slots and TS3, TS4, TS5 and TS6 are downlink time slots in the indoor cell; and symmetry TS allocation is made for the outdoor cell. In the intra-frequency cell network, it can cause intra-frequency interference between cells. So the research on the intra-frequency crossed time slots interference is done and the suggestions on the intra-frequency crossed time slots networking strategy are proposed in this paper.
