Abstract
In Time Division Long Term Evolution(TD-LTE) system, decreasing the cross time slot interference is very important to improve the system throughput. Accordingly, we will propose a multi-cells Orthogonal Frequency Division Multiplexing(OFDM) resource allocation model for TD-LTE system in this paper, which considers the cross time slot interference and the fairness. Subsequently, a TD-LTE resource allocation evolutionary algorithm based on adaptive fairness threshold is proposed to solve this model through introducing adaptive fairness threshold. Empirical studies show that the proposed model and algorithm can effectively decrease the cross time slot interference and improve the transmit rate of OFDM system under the same fairness.
