Millimeter wave communication network architecture and device

Abstract

The invention relates to a millimeter wave communication network architecture. Control signals of the communication network and the user data are relatively separated by adopting two or more layers of a hybrid network of a macro cell and a micro cell / picocell, wherein the macro cell is deployed at the low band frequency, and is covered by adopting an omnidirectional or sector antenna; the control signals are transmitted through the macro cell; the micro cell / picocell is deployed at the high band frequency, and adopts a large-scale antenna array; and the user data is transmitted through the overlapped micro cells / picocells. The invention also relates to a base station and terminal based on the millimeter wave communication network architecture. According to the millimeter wave communication network architecture, the base station and the terminal disclosed by the invention, the control signals and the user data are relatively separated, and meanwhile, the user business connection and high-speed data transmission in a wide range can be maintained, the quality of links can be increased, and the mutual interference can be reduced.

Description

technical field [0001] The present invention relates to the technical field of millimeter wave communication, in particular to a millimeter wave communication network framework and device. Background technique [0002] Wireless communication is developing towards ultra-high speed and large capacity, and there is an urgent need for large-capacity high-speed transmission systems for point-to-point interconnection and wireless backhaul. Spectrum resources available in frequency bands below 3 GHz with relatively good wireless propagation characteristics are very scarce, but there are 252 GHz spectrum resources available in the 3 GHz to 300 GHz frequency band (wavelengths from 1 to 100 mm, collectively referred to as millimeter waves), and the available spectrum resources are More than 200 times the available spectrum resources below 3GHz at present. Therefore, it is one of the trends in future research and development of wireless communication networks and systems to use the pr...
