摘要

5G室内外采用同频部署会导致网络覆盖性能和用户业务体验下降，分析了室内外同频干扰产生的原因，对业务信道物理资源块（physical resource block，PRB）随机化干扰解决方案、室内外波束协同干扰解决方案、室内多波束干扰解决方案 3 种室内外同频干扰解决方案原理进行了系统的研究，并且针对室内外同频干扰的影响程度进行了测试验证，经过验证业务信道PRB随机化干扰解决方案中业务负载在30%左右时，抑制干扰的效果最好；室内外波束协同功能在室外宏基站邻区空载或者高加扰（70%）时，开启该功能对下行速率的提升更明显；开启室内多波束功能后下行速率要明显高于单波束情况。最后给出了同频干扰控制方案部署建议。

Abstract

5G indoor and outdoor deployment with the same frequency will lead to the decline of network coverage performance and user service experience.The causes of indoor and outdoor interference with the same frequency was systematically analyzed.The principle of three indoor and outdoor co-channel interference solutions

namely PRB random interference solution

indoor and outdoor beam cooperative interference solution and indoor multi beam interference solution were studied.The results show that the PRB random interference solution has the best interference suppression effect when the traffic load is about 30%.When the indoor and outdoor beam cooperation function is turned on when the adjacent area of the outdoor macro station is no-load or high load (70%)

the improvement of the downlink rate is more obvious.When the indoor multi-beam function is turned on

the downlink rate is significantly higher than that of single beam.Finally

the deployment suggestions of co-channel interference control scheme were given.
