Abstract

The invention discloses a millimeter-wave return optimization method capable of being applied to a millimeter-wave wireless return system, which comprises the steps that a massive multiple-input multiple-output and dense small-cell two-layer heterogeneous network system is established; communication waves of a millimeter wave frequency band are adopted between a macro base station (MBS) and a basestation (BS), and millimeter waves are adopted between the base station and a user for wireless return communication; the user obtains energy from the base station through wireless power transmissionequipment; the power loss and energy efficiency of millimeter wave wireless return in the system are calculated; and the power loss and energy efficiency are calculated in the system adopting a millimeter wave return optimization scheme; and the steps are compared to obtain an optimal result. The millimeter-wave return optimization method has the advantages that the communication interference isreduced, the spectrum efficiency is improved, and the energy efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless backhaul system applied to communication resources in the millimeter wave band in a network. Background technique [0002] With the development of the Internet and communication technology, the rapid popularization of advanced communication devices (such as smart phones, tablet computers and notebook computers, etc.) and multimedia services, some industry and academic experts predict that the demand for mobile data transmission will increase by 1000 times by 2020. Although modern wireless communication systems are constantly changing our daily lives and even changing our behavior habits, the carrier problem of wireless backhaul and the optimization of the transmission power of the backhaul channel in the communication system are still a problem that hinders the development of communication technology. On the other hand, the continuous development and mat...
