[摘要] 毫米波是第5代移動通信系統(tǒng)的重要通信技術，利用大帶寬承載大量信息，有效提升系統(tǒng)的吞吐量。第3代合作伙伴項目（3GPP）標準已經(jīng)對毫米波頻段做了劃分，各個國家逐步對頻譜進行分配。毫米波因其頻譜特性，需要與大規(guī)模天線陣列結合使用，獲得波束賦形增益。通過對波束設計與波束管理等核心技術的創(chuàng)新，實現(xiàn)熱點高速傳輸。同時，通過高低頻無線協(xié)作組網(wǎng)的方式，實現(xiàn)整個區(qū)域內的基礎覆蓋，以適應不同的通信場景需求。

[Abstract] Millimeter wave is an important technology for the 5th generation mobile communication system. By utilizing wide frequency band for high data transmission, millimeter wave can greatly increase the experienced data rates of users and the system throughput. The millimeter-wave bands have been standardized by third Generation Partnership Project (3GPP), and the spectrum has been allocated gradually by many countries. Due to its spectral characteristics, millimeter waves need to be combined with large-scale antenna arrays to obtain beamforming gain. The high-speed transmission of hotpots is realized by the innovation of beam design and beam management. In addition, the basic coverage in the entire area and the requirement for different communication scenarios can be satisfied by multi-frequency wireless cooperative networking.

[Keywords] millimeter wave; hybrid beamforming; beam management; multi-frequency cooperative networking
