Method and device for realizing intelligent beam registration by using network environment context information

Abstract

The invention discloses a method and a device for realizing intelligent beam registration by using network environment context information. The method comprises the following steps: calculating transceiving beam pair information corresponding to a communication link for data transmission according to positions of a base station and a mobile terminal, network environment context information and influence information of a surrounding transmission medium on electromagnetic transmission; judging whether effective communication link information corresponding to the corresponding information is stored in a knowledge graph library or not according to the base station position, the mobile terminal position and the weather information; if so, directly selecting transceiving beam pair information corresponding to a communication link for data transmission, otherwise, obtaining real-time transceiving beam pair information through traditional beam training or reconstructing a communication environment stereotactic diagram to calculate switching beam pair information. According to the method, the beam switching position of the mobile terminal is predicted by using an artificial intelligence theory, so that the switching beam pair is pre-estimated. According to the invention, low-overhead training and efficient beam registration can be realized and a communication link can be established ina mobile communication scene.

Description

Technical field [0001] The present invention relates to the field of wireless communication, and in particular to an intelligent beam registration method and device realized by using network environment context information. Background technique [0002] The 5th Generation mobile communication technology (5G: The 5th Generation mobile communication technology) standard-making organization 3GPP plans to use the millimeter wave frequency band (10-300 GHz) with rich spectrum resources to solve the fourth generation mobile communication technology (4G: The The 4th Generation mobilecommunication technology) LTE-A (Long Term Evolution-Advanced) system faces the problem of tight spectrum resources. However, the propagation in the millimeter wave frequency band faces problems of path loss and penetration loss. The directional transmission based on the large-scale antenna array can effectively compensate for the high path loss, and the dense deployment of base stations is also a remedy fo...
