| 摘 要： | 协作多点传输（CoMP）是3GPP长期演进（LTE）的一个重要技术点，并将在上行采用多用户MIMO技术。分析了上行构成多用户MIMO的用户配对选择方法，并提出了一种在物理层进行用户传输速率公平性的调度方法，使系统在单个用户性能与整个系统的频率效率间取得较好的折衷。用系统仿真的方法对系统性能进行了仿真，证明了所提出算法的有效性。

| Abstract: | Coordinated multi-point transmission/reception（CoMP） is one of the candidate techniques for LTE-advanced systems to increase the cell average and cell edge user throughput in both uplink and downlink. In this paper, the partnership schemes were compared for uplink multiple input and multiple output multi-user systems, and one updated scheme based on faire schedule of user transmission data rates. With this scheme, the performances of user and spectrum efficiency of systems can make a good tradeoff, and the proposed algorithm was verified by system simulation. |
