Optimization methods on the planning of the time slots in TD-SCDMA system
Zhipeng Jiang, Shuzhi Gao · 2013
TD-SCDMA is the third-generation mobile communication standard of our country that adopts time slot duplex and code division multiple access (CDMA). Time slots planning, i.e. the division of uplink and downlink time slots, is critical in TD-SCDMA. Most existing algorithms and strategies are greedy algorithm, which can't ensure the optimality or approximate optimality of the result. In this paper, some optimization models on the planning of the time slots for single channel problem and multiple channel problem are proposed. The simulation result show that our method can get a good result.
