协调多点或协作MIMO是有前途的概念之一，以提高小区边缘用户数据速率和频谱效率，超过LTE或WiMAX的第一版中的MIMO-OFDM的可能性。可以通过扇区之间或不同站点之间的合作来利用或减轻干扰。对于上行链路和下行链路都可以示出显著的增益。确定并部分解决了一系列技术挑战，例如回程流量、同步和反馈设计。这篇文章还显示了COMP在两个现场测试平台上的主要可行性，这些测试平台具有多个站点和站点之间的不同回程解决方案。这些活动是由大学、芯片制造商、设备供应商和网络运营商组成的强大联盟开展的。
Coordinated multipoint or cooperative MIMO is one of the promising concepts to improve cell edge user data rate and spectral efficiency beyond what is possible with MIMO-OFDM in the first versions of LTE or WiMAX. Interference can be exploited or mitigated by cooperation between sectors or different sites. Significant gains can be shown for both the uplink and downlink. A range of technical challenges were identified and partially addressed, such as backhaul traffic, synchronization and feedback design. This article also shows the principal feasibility of COMP in two field testbeds with multiple sites and different backhaul solutions between the sites. These activities have been carried out by a powerful consortium consisting of universities, chip manufacturers, equipment vendors, and network operators.
