| 摘 要： | LTE-Advanced( LTE-A)系统引入中继后,带来了如提高频谱效率、拓展网络覆盖等优点,但是也给资源分配带来了更多的挑战.针对LTE-A中继系统的下行资源分配问题,在资源足够使用的情况下,提出一种在eNB和中继功率受限且用户数据速率限制的条件下,以权衡系统吞吐量和用户公平性为目标的资源分配机制.通过仿真验证表明,该算法较好地权衡了系统吞吐量和用户公平性,并且能满足用户速率要求.

| Abstract: | Introducing relays in LTE-Advanced(LTE-A) system,brings lots of advantages,such as improving spectrum efficiency and expanding network coverage etc.However,it also brings more challenges for resource allocation.A resource allocation mechanism is proposed for LTE-A relay system in case that there are sufficient resources to use.The objective is to trade off system throughput and a fairness index with the eNB and relay power constraint while meets users’ QoS and minimum rate requirements.Simulation results show that the proposed algorithm provides robust fairness,achieves good system performance and satisfies every user rate requirements. |
