摘　　要：目前4G向5G重耕过程中存在频谱利用不平衡的问题,可采用动态频谱共享的技术解决。基于对现有频谱共享方案的原理分析,通过理论测算和实验室测试结合的方法研究终端和基站各功能特性对于终端性能的影响。动态频谱共享对下行影响较大,对上行影响较小,不同功能选择会对性能带来差异,同时频谱方案、基站通道数同样会带来性能差异。基于结果分析,提出4G和5G频谱共享的实施方案,包括硬件配置方案、频谱选择方案、通道配置方案、功能选择方案,以改善现网的性能。For the problem of unbalanced spectrum utilization in the re-farming process from 4 G to 5 G, it can be solved by dynamic spectrum sharing technology. Based on the principle analysis of the existing spectrum sharing scheme, this paper investigates the influence of each functional characteristic of the terminal and the base station on the terminal performance through the combination of theoretical calculation and laboratory testing. Dynamic spectrum sharing has a greater impact on the downlink and less on the uplink. Different function selections bring differences in performance, and spectrum schemes and the number of base station channels also bring different performances. Based on the analysis of the results, an implementation solution for 4 G and 5 G spectrum sharing is proposed, including hardware configuration, spectrum selection, channel configuration, and function selection to improve the performance of the existing network.
