摘　　要：结合目前5G新空口频率分配现状,针对5G NR频段无线传播能力不足的问题,提出NR与LTE上行载波共享方案,同时深入分析方案中涉及的NR频域子载波配置、时域时间偏移和路径损耗估算等关键技术问题,以及对NR与LTE组网性能的影响,并结合技术分析提出载波共享技术的配置建议、局限性与发展前景。According to the status of existing 5G new air interface frequency allocation and the deficiency of5G NR frequency band in RF propagation capability, the sharing scheme of NR and LTE uplink carrier was proposed. The key technical problems in the scheme such as subcarrier configuration in NR frequency domain, time offset in time domain and path loss estimation were analyzed in depth. Besides, the impact of NR and LTE sharing performance was addressed. Finally, the suggested configuration, limitation and developmental perspective of carrier sharing were presented based on technical analysis.
