Abstract

In order to advance the transmission data rate and meet the traffic needs of users, the higher requirements for wireless communication system radio resource management was put forward by mobile operators. Meanwhile, considering lower rate radio resource utilization resulted from unreasonable particle size of resource allocation in existed researches on LTE-A uplink frequency domain scheduling, a dynamic resource allocation scheme based on sliding window is proposed to improve the performance. The program determines the user's resource allocation size dynamically relay on the required one. And the sliding window mechanism is used to search the optimal channel quality resources for the user in the whole system resource. Simulation results show that compared to the fixed resource granularity of traditional programs, the dynamic resource allocation scheme based on sliding window gains more significant improvement in the system throughput and RB utilization and effectively improves the system spectral efficiency.
