摘　　要：随着5G网络部署,4G网络与5G网络将在未来一段时间内并存。在此情况下,二者需有效协同,优势互补。为解决4G网络与5G网络协同问题,首先分析了基于4G/5G协同的2.6 GHz和4.9 GHz帧结构配置方案,研究了协同组网中半静态和动态频谱共享策略,分析了语音协同能力和上下行链路预算,最后在此基础上主要对比分析了2.6 GHz和4.9 GHz频段下的路径损耗和覆盖预算,通过研究,为5G网络建设策略制定提供了技术指导。With the deployment of 5G networks, 4G and 5G networks will coexist in future. In this case, 4 G and 5 G need to effectively collaborate to seek complementary advantages. In order to solve the collaboration issue of 4G and 5G, this paper first analyzes the frame structure configuration solution of 2.6 GHz and 4.9 GHz based on 4G/5G collaboration. Then semi-static and dynamic spectrum sharing strategies are studied in collaborative networks, and the voice collaboration capability and uplink and downlink budgets are analyzed. Finally, on this basis, the main comparison of path loss and coverage budget in the 2.6 GHz and 4.9 GHz frequency band provides the technical guidance for 5 G network development strategy through investigation.
