摘要：
The code division multiple access system with time division duplex mode (CDMA/TDD) where the same frequency allocation is made for both uplink and downlink is a good solution when the traffic asymmetry between uplink and downlink exists. However when the asymmetry of each cell may be significantly different from each other, the traffic may experience severe interference from each other when each cell's own slot allocation is made according to the level of traffic asymmetry in each cell. The interference in the W-CDMA/TDD system when the slot allocations are made according to traffic patterns of each cell is analyzed, and a time slot allocation scheme considering the traffic asymmetry is proposed. In this paper system performances are simulated under the proposed time slot allocation strategy and its optimal operation of the strategy is investigated.
