Abstract: The total power received in Base Station(BS) reflects the situation of traffic load in uplink in central cell and adjacent cells. Based on this principle, a dynamic distribution scheme of traffic load in WCDMA system is proposed in this paper. The central Base Station(BS) periodically adjusts the power of pilot signal according to the total power received in uplink. Mobile Station(MS) is able to hand off between central cell and surrounding cells smoothly, so the dynamic distribution of traffic load is realized. The results of simulation indicates that this scheme can get good performance, the block probability and the dropping probability in uplink and downlink can be improved.
