蜂窝上行链路中的协作多点 (CoMP) 似乎是对抗小区间干扰的有效选择，可大幅提高频谱效率和公平性。然而，这些方案的一个主要缺点是，与非协作系统相比，它们通常需要大量额外的回程基础设施。关于这个主题已经发表了大量的理论工作，强调根据信道实现在不同的 CoMP 策略之间进行调整以优化速率/回程权衡的好处。本文通过在代表性城市环境中获得的现场试验结果对之前的出版物进行了补充。结果深入了解与某些方案相关的实际问题，同时与理论预测相当相关，并且实际上进一步强调了自适应 CoMP 的增益
Coordinated multi-point (CoMP) in the cellular uplink appears to be an effective option to combat inter-cell interference, offering large improvements in spectral efficiency and fairness. However, one major drawback of these schemes is that they typically require a large extent of additional backhaul infrastructure compared to a non-cooperative system. A large amount of theoretical work has been published on this topic, emphasizing the benefit of adapting between different CoMP strategies depending on the channel realization in order to optimize the rate/backhaul trade-off. This paper complements previous publications through field trial results obtained in a representative urban setup. The results yield an insight into practical issues connected to some schemes, while being fairly correlated to theoretical predictions and in fact further emphasizing the gain of adaptive CoMP
