Abstract

This paper investigates the performance improvement of new channel re-assigning scheme during the inter-system handover from 1.28 Mcps TDD mode. Two proposed structures describes the use of asymmetric time-slot allocation pattern and the combination of time-slot allocation pattern of traffic channel. Each proposed scheme can be applied to the handover scenario to UTRA/FDD mode and UTRA/TDD mode with 3.84 Mcps chip rate from 1.28 Mcps TDD mode, respectively. Simulation results shows that the proposed structure attains the longer measurement time for target system to enhance the reliability of measurement and also increase the probability of successful synchronization. In conclusion, improvement of handover performance can be achieved by proposed scheme, but the impact from beam-forming and power control operation should be considered as a further study area.
