| Abstract: | Due to multi-user detection and smart antenna techniques,the radio resource management schemes for WCDMA and cdma2000 systems could't be adopted for TD-SCDMA directly.Based on the theoretical analysis of the smart antenna and multi-user detection impacting on the system's capacity,an available capacity and load estimation model were proposed,and an advanced admission control algorithm was presented.Meanwhile,a novel admission control and a dynamical channel allocation(DCA)scheme were proposed.Simulation results show that the proposals are available for TD-SCDMA,which can help network planning and optimization. |

| Keywords: | TDD-CDMA radio resource management dynamical channel allocation smart antenna |
