Two-way communication system and beam tracking method

Abstract

The present application relates to a two-way communication system and a beam tracking method. The two-way communication system includes a communication base station and a communication terminal, wherein the communication base station includes a phased array antenna and a beam tracking controller; the beam tracking controller is used to detect the current signal received by the phased array antenna from the communication terminal Whether the power difference between the wireless signal and the reference wireless signal is less than a first difference threshold; the beam tracking controller is further configured to control the phased array antenna to scan when it is detected that the power difference is less than the first difference threshold, The phased array antenna is aligned with the communication terminal until the power difference between the wireless signal sent by the communication terminal and the reference wireless signal received by the phased array antenna during the scanning process is greater than a second difference threshold. The method can realize the real-time two-way mobile communication of the user terminal based on the millimeter wave or terahertz and other high frequency band wireless signals.

Description

Technical field [0001] The present application relates to the field of wireless communication technology, in particular to a two-way communication system and a beam tracking method. Background [0002] With the continuous development of information technology, the amount of data transmitted and processed by real-time communication has increased exponentially, however, the increasing shortage of spectrum resources in the low frequency band has made the traditional wireless communication support capacity-hungry applications a huge challenge. In order to meet the needs of future wireless communications, it is an inevitable trend to develop high-band spectrum resources to achieve high-speed, broadband wireless communications. Millimeter wave and terahertz bands, etc., due to their high frequency band width, have significant advantages such as high data transmission rates and high throughput, which can meet the needs of users and applications for ultra-high data traffic. However, exis...
