Description
Summary:In this paper, we develop a scheduling algorithm to obtain multi-user diversity for those low-mobility users and frequency diversity for those high-mobility users. Computer simulation demonstrates that the proposed scheduling algorithm provides 10% and 16% overall cell throughput gain over proportional fairness based frequency-selective and frequency-diversity scheduling algorithm, respectively. In addition, the proposed scheduling algorithm is shown to have the same order of computational complexity as the frequency-selective scheduling algorithm, and can be easily implemented in the LTE downlink systems.
