本文分析了物理层多天线增强对无线网络链路层性能的影响。我们首先保留了以网络为中心的设计理念，并描述了MIMO增强对面向稳定性的调度程序设计的影响。在稳定最优运行下，我们用平均时延和系统的功来量化效益。最后，在最小服务提供的方法中讨论了MIMO的使用，这与相反的以用户为中心的设计理念有关
This article provides an analysis of the impact of the multi-antenna enhancement of the physical layer on the link layer performance of a wireless network. We first remain within the network-centric design philosophy and characterize the influence of MIMO enhancement on the stability-oriented scheduler design. We quantify the benefits in terms of average delay and work in the system under stability-optimal operation. Finally, the use of MIMO is discussed in the approach of minimum service provision, pertaining to the opposite user-centric design philosophy
