Abstract

In order to make full use of channel, a new dynamic channel allocation algorithm for TD-HSPA system is proposed. The proposed algorithm gives priority to consider the time slot distribution in uplink channels. This paper uses low order modulation coding in uplink channels, but uses high order modulation coding in downlink channels. The transmission rate of uplink and downlink are asymmetric. In his paper, we propose a criterion sharing channel for each other through main and auxiliary frequency when the voice channel is idle. As a result, the system capacity is increased 50% larger than the past. Simulation results show that the proposed algorithm can decrease the call blocking ratio and dropping packet rate of data service, improve the channel utilization efficiency, and increase the number of data users dramatically.
