A Self-adaptive Time Slot Allocation Algorithm Based Low Value of SINR in TD-LTE System
Yao Zhongmin,Lu Yanyang,Liu Wei,Si Hongyan 보안공학연구지원센터 2015 International Journal of Future Generation Communi Vol.8 No.6
In time division duplex Long Term Evolution (TD-LTE) system, the protocol provides 7 different time slot configurations. Only one fixed time slot deployed in mobile network. This paper proposed a dynamic time slot allocation algorithm, the system according to the user equipment (UE) detected the environmental signal to interference and noise ratio (SINR) to dynamically decide the time slot configuration, especially the UE in the situation of relatively bad wireless environment and the lower SINR value, can adopt the polling algorithm, obtained the dynamic time slot configuration. This method is simple in calculation, can reduce redundant computational burden in the system. The result of simulation demonstrated that the algorithm has significant effect in improving the networking throughput、 increasing the system spectrum utilization rate.
