基于4G数据识别5G室内外同频干扰的方案研究

Research on the identification of 5G indoor and outdoor intra-frequency interference based on 4G measurement reports

目前中国移动主要基于2.6 GHz频段开展5G网络建设,由于室分系统和宏站共用100 MHz频谱,因此室内外同频干扰会对5G用户感知产生不利影响。本文提出了一种基于4G测量报告快速识别室外5G高干扰小区的技术方案,可用于识别5G室内外高干扰小区。研究分析和测试验证表明:该方案可快速发现并定位室内外同频干扰覆盖问题,有助于辅助制定网络优化措施。

China Mobile mainly carries out 5G network construction based on the 2.6 GHz spectrum.Since the indoor and the macro base stations share 100 MHz spectrum resources,it affects the progress of 5G deployment and user perception improvement whether the problem of indoor and macro intra-frequency interference can be effectively resolved.In this paper,we propose a method how to quickly identify interfering cells by combining data modeling of 4G serving cell RSRP and neighboring cell RSRP,and finally obtain top indoor and macro 5G interference cells.Research analysis and test verification intuitively indicate that this method can quickly fi nd and locate the problems of indoor and outdoor intrafrequency interference coverage and help to formulate network optimization measures.
