Abstract

For future 6G communication systems, higher millimeter wave frequency band are considered, especially E-band, which could be used in high-capacity mobile communication system in the integrated access and backhaul as well as airborne high speed communication. In this paper, the status of E-band high-capacity mobile communication system is reviewed. E-band communication system is mainly aimed at point-to-point applications. It adopts reflector antenna and mechanical scanning, with low integration and heavy weight. In order to further adapt to the application of high-capacity and high dynamic platform, it is necessary to improve the system architecture, RF antenna, modulation mode, tracking and aiming, etc. In this paper, trends of E-band high-capacity mobile communication system are proposed, including architecture, low cost phased array, high order modulation and demodulation, and spatial multiplexing. First, future E-band mobile communication system must adopt phased array to adapt to the high-speed and high dynamic environment. For the system architecture trend, analog-digital hybrid beamforming architecture should be used to achieve the balance between performance and cost. Multi-functional integrated chip and RF antenna integration technology are adopted to improve the integration of antennas, reduce the interconnection loss between RF and antennas, and ensure the signal consistency of the system. In terms of modulation mode, high-order modulation and demodulation should be adopted, such as 64QAM, 256QAM, for the air-to-air and air-to-ground channels. LOS-MIMO and other spatial multiplexing technologies are adopted to improve the system capacity further.
