WCDMA, TD-SCDMA and CDMA2000 three major standards for the third generation mobile communication system , which WCDMA is the mainstream of the mainstream . WCDMA system when HSUPA users increased consumption of CE also increasing , it may become a bottleneck . First specific HARQ, short frame length , soft handover and NodeB fast scheduling technology - based functions , features , principles , and these new technologies in the WCDMA system . And then focuses on the NodeB controlled scheduling , the original algorithm is improved by the the initial CE allocation changed according MinSF initial CE allocation according GBR , to join five CE adjusting step in the cycle : service RLS user the CE resource recovery service RLS users CE CE fairness adjustments, non- users of services RL the CE processing and maximize the use of CE resources processing . Finally, the improved algorithm simulation , the simulation results show that the improved algorithm reduces the latency of the system , the base station CE utilization , and to reduce the occurrence of congestion .
