5G室内外同频组网条件下提升室内小区流量承载比的方法
Methods to Enhance Indoor Cell Traffic Load Ratio under 5G Indoor-Outdoor Co-frequency Networking Conditions
摘要
Abstract
To achieve higher frequency utilization efficiency,5G network planning adopts indoor-outdoor co-frequency networking.Under these conditions,5G UEs located at the edges of buildings,if residing in outdoor cells,can severely impair network performance due to co-frequency interference.To encourage building-located 5G UEs to reside predominantly in indoor cells,a flexible adjustment of the 5G SSB(Synchronization Signal Block)frequency points is employed using a global channel number.By maintaining the same 5G carrier frequency band,this approach differentiates the SSB frequency points of indoor and outdoor cells,transforming the network from co-frequency and co-channel to co-frequency but different channels.Concurrently,the optimization of handover thresholds for different channel networking,setting the highest reselection priority for 5G indoor cells,and adjusting related priority-based reselection thresholds are undertaken.The ultimate goal is to maximize the residence of indoor 5G UEs in indoor cells.Field verifications in live networks demonstrate that after adjusting the SSB frequency points for indoor and outdoor cells and related handover and reselection parameters,the traffic load ratio of indoor cells improved by approximately 30%.This indirectly confirms that more indoor 5G UEs reside in indoor cells.Thus,different channel networking within the same frequency band effectively enhances the indoor cell traffic load ratio under indoor-outdoor co-frequency conditions,offering a reference for ensuring the effectiveness of 5G indoor coverage projects.关键词
