摘要
阐述了5G系统毫米波焦点频段(26 GHz频段)全球频谱划分与现有应用概况,对全球研究动态与主要国家和地区的初步观点进行了梳理与总结。结合本频段现有无线电业务应用情况,重点剖析了开展频谱兼容性研究的关键场景、研究方法与主要挑战。最后,对5G系统有助于兼容共存的特征进行了归纳,为后续研究指明了方向。相关内容可为该频段5G频率规划提供借鉴。
For the5G hotspot millimeter wave(MMW)frequency band(26GHz),this paper elaborates the global spectrum allocation and existing applications,and summarizes the global research trends and the preliminary views of some countries and regions.Then,according to other incumbent spectrum users in this band,it analyzes the key scenarios,methodologies and challenges of sharing and compatibility studies.Finally,it summarizes the features of5G system which are helpful to the compatibility with the existing radio services,and gives suggestions for future research.The contents in this paper can support the5G frequency planning in this band.
