Load balancing is an important technique in Radio Resource Managements (RRM). In future, when several frequencies are required to cover increasing number of users and increasing amount of traffic, Inter-Frequency HandOver (IFHO) will perform an important role in load balancing between frequencies. Meanwhile, there is usually geographical load imbalance in real network and changing coverage by tuning Common PIlot CHannel (CPICH) power can mitigate this geographical load imbalance. In this context, the authors evaluated the RRM techniques combining IFHO and CPICH power tuning for balancing load and for achieving better performance by using a dynamic WCDMA simulator.
