摘要
目前我国C-band主流频段的5G网络皆采用TDD模式,与FDD模式不同的是,若TDD基站下行信号传播时延超过GAP长度,落入其他基站上行接收窗口,则会产生远端干扰,严重影响上行业务质量。针对5G远端干扰,目前业内主流优化方案分为修改系统时隙结构、受扰端干扰抑制及干扰源自主降扰3类。分别论述了以上3类方案的技术原理,并通过实际优化实践对比了其效果。
At present,the 5G networks of C-band in China adopts TDD mode.Unlike FDD mode,if the downlink signal propagation delay of TDD base stations exceeds the GAP length and flls into the uplink receiving window of other base stations,it will generate remote interference,seriously affecting the quality of uplink services.In view of 5G remote interference,the current mainstream optimization solutions in the industry are divided into three categories:modification of the time slot structure,interference suppression at the victim site,and independent interference reduction at the interference sources.The technical principles of the above three types of schemes are discussed separately,and their effects are compared through practical optimization practices.
