Embodiment Construction

[0053] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0054] The invention mainly optimizes and improves the beam management process of massive MIMO millimeter wave, and can add the function module of mobile edge computing MEC to the millimeter wave base station, so that it has storage and computing capabilities, and uses the CF collaborative filtering algorithm (recommended algorithm) The matching operation process is used to realize the recommended matching of the beam scheme, so as to replace the relatively complicated beam matching training process of the traditional protocol with the technical scheme of intelligent matching, and improve the management efficiency of the beam.

[0055] The general process of the beam management method for massive MIMO millimeter-wave communication according to the present invention is as follows: after the mobile terminal enters the cell covered by the millimeter...

Abstract

The present invention relates to a beam management method for massive MIMO millimeter wave communication and a massive MIMO millimeter wave base station, which utilizes CF collaborative filtering algorithm matching and intelligent path prediction to generate an efficient and continuous dynamic beam operation scheme, thereby reducing the complexity of the prior art. In the relatively complicated operation process of beam management, the present invention replaces the original relatively numerous and mechanically repeated time slot overhead with an intelligent analysis method, thereby improving the operation efficiency of beam management. The present invention achieves the same effect as the beam management in the prior art by adding condition judgment and corresponding execution actions in each unit analysis process, that is, ensuring consistency with the protocol process in the prior art, and can be found in the current situation. The most suitable transmit and receive beam pair between the transceiver equipment performs high-quality beam connection communication to ensure the completeness of the operation of the beam management method.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more particularly, to a beam management method for massive MIMO millimeter wave communication, and a massive MIMO millimeter wave base station. Background technique [0002] Due to the technical advantages of high transmission rate and large communication capacity, millimeter wave can make full use of space resources and double the system channel capacity without increasing spectrum resources and antenna transmit power. However, millimeter wave also has disadvantages such as large signal attenuation, short coverage distance, and easy blocking. Therefore, the existing technology combines massive MIMO and uses beamforming technology to focus the beam in a fixed direction, so as to concentrate the transmit power and the receiving area on a narrow beam, thereby improving the calculation accuracy of the transmit angle and the arrival angle, and at the same time Compensate for...
