Fast dynamic channel allocation scheme based on TD-SCDMA system

According to the frame characterristic of TD-SCDMA system,an improved boundary strategy dynamic channel allocation(MB DCA) scheme applicable for the system was proposed,which is a mixed data rate and small grouping borrowed MB DCA scheme.This scheme can solve the problem of low channel borrowed efficiency in the case of mixed data rate,make MB strategy more flexible,and improve system capability through small grouping borrowed.Simulation results show that the proposed scheme can update data service capability and increase channel utilization efficiency without affecting voice service performance.
