摘要
对于同频干扰严重的重叠覆盖场景,Co MP可提高边缘用户SINR,降低小区间干扰,提高边缘用户的吞吐率。对下行Co MP技术进行介绍,并重点介绍了5G下行Co MP与技术与LTE下行Co MP的主要差异,5G下行Co MP JT的基本原理以及具体的实现流程。针对2种场景,对5G下行Co MP JT技术进行了性能验证及分析。测试结果表明,服务小区和协作小区RSRP差值越小,服务小区和协作小区之间的相关性越低,提升流数的同时流间干扰越低,增益越大。
For overlapping coverage scenarios with severe co-frequency interference, Co MP can enhance the SINR of edge users, reduce inter-cell interference, and improve the throughput of edge users. This paper introduces the downlink Co MP technology, and focuses on the main differences of downlink Co MP technologies between 5 G and LTE, the basic principles of 5 G downlink Co MP JT, and the specific implementation process. The performance verification and analysis of the 5 G downlink Co MP JT technology are carried out for two scenarios. The test results show that the number of streams is increased while the inter-stream interference is reduced and thus the greater gain is achieved with a smaller RSRP difference and a lower correlation between the serving cell and the coordinated cells.
