A Perceptual Viewpoint on the Issues of 5G Mobile Radio Systems

The issues addressing in 5G (fifth generation) wireless communication systems are reviewed in this article. The standard 5G radio network protocols are not yet definitely defined. A huge number of studies with research reports have been published on the subject of 5G systems. According to the basic viewpoint of radio systems, the adopted radio MMW (millimeter wave), the MIMO (multiple-input multiple-output) beam forming transmission technique, and the green communication cognitive radio signalling concept are becoming very hot research topics. This report is based on reviewing the new events for 5G wireless communications, and aiming at deploying 5G issues for audiences to follow up and peak their interest.

本文著重於第五代（fifth generation, 5G）無線通訊系統議題的認知式回顧。雖然，5G通訊網路的所有標準協定尚未塵埃落定，其相關之研究成果已有十分大量地研究報告出爐。根據無線通訊系統的基本觀點，採取之無線毫米波（millimeter wave, MMW），多輸入多輸出（multiple-input multiple-output, MIMO）波束成型（beam forming）傳輸技術，以及綠能通訊觀念，及至感知無線電（cognitive radio）訊號的應用等等，全部相關於5G之探討，正逐漸地變成非常熱門的研究議題。基於5G無線通訊之新事件的回顧，作者於文中聚焦於探討提出一些5G系統的熱門研究議題，作為提供給予此一研究領域之讀者在部署相關研究議題時可以遵循，而且是足以引起共鳴的一些5G研究議題之上。
