A Novel Dynamic Channel Allocation Scheme to Support Asymmetrical Services in TDD-CDMA Systems
TDD-CDMA系统中支持非对称业务的动态信道分配算法研究

In TDD-CDMA system, the different asymmetrical requirements between uplink (UL) and downlink (DL) in different Base Station (BS) and different time will generate serious inter-cell interference. From the interference point of view, Dynamic Channel Allocation (DCA) is treated mandatorily on TDD-CDMA systems. In this paper, a novel and advanced DCA algorithm is presented, which is based on radio resource reserving related to pathless assistance and BS-BS interference resolving mechanisms. Simulation results show the novel DCA can work better than the traditional DCA schemes for asymmetrical traffic.
