摘要: 通过分析亚太地区对IMT-2020各候选毫米波频段的观点,提出将40.5~42.5 GHz作为进一步研究的候选频段.在IMT-2020毫米波场景下,给出了面向大规模天线波束赋型的室内热点和密集城区2种测试环境,通过耦合损耗和用户信干噪比来分析测试环境下的毫米波信道特征,并对关键技术指标小区平均频谱效率和小区边缘用户频谱效率进行评估,经观察发现,2种测试环境的评估结果均满足ITU-R定义的要求.

Abstract: 40.5~42.5 GHz is considered as a candidate of IMT-2020 bands by analysis current status of each country in Asia-Pacific region and IMT-2020 scenarios of related millimeter wave, both indoor hotspot and dense urban test environments are defined, based on massive multiple-input multiple-output beamforming. Meanwhile, coupling loss and signal to interference plus noise ratio distribution are applied to study channel characterizes of each test environment. Finally, introduced both average cell spectral efficiency and 5th percentile user spectrum efficiency evaluates each test environment; and their evaluated results meet defined requirements by ITU-R.

Key words: IMT-2020 system, millimeter wave, channel characteristics, evaluation methodology
