摘要
5G将进入网络融合化、终端和业务多样化的时代,无线网将出现GSM/TDD/FDD/NB/pre5G/5G多制式共存、900MHz/1800MHz/F/D/E/A6频段15频点并存的局面。由于业务分层承载,现有的4G和5G相互影响、需要兼顾,网络结构前所未有的复杂,无线优化工作形势严峻。分析了5G无线优化工作面临的困难和挑战,提出了5G无线优化的应对策略。
The era of network convergence,terminal and business diversification in 5 G stage is coming.The radio network will have the situation of coexistence of GSM/TDD/FDD/NB/pre5 G/5 G/WLAN multi-mode and 900MHz/1800MHz/F/D/E/A6-band 15 frequency points.Due to the layered service carrying,the existing 4 G and 5 G interact with each other,which needs to be taken into account.The network structure will be unprecedented complex,and the wireless optimization work situation will be severe.The difficulties and challenges of 5 G radio optimization were analyzed,and the strategies to deal with 5 G radio optimization was put forward.
