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、900 MHz/1 800 MHz/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。

Abstract:

The era of network convergence,terminal and business diversification in 5G stage is coming.The radio network will have the situation of coexistence of GSM/TDD/FDD/NB/pre5G/5G/WLAN multi-mode and 900 MHz/1 800 MHz/ F/D/E/A6-band 15 frequency points.Due to the layered service carrying,the existing 4G and 5G 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 5G radio optimization were analyzed,and the strategies to deal with 5G radio optimization was put forward.

Key words: 5G, radio optimization, massive MIMO, NSA, SA, anchor, artificial intelligence
