Ground-to-air coverage scenarized beam generation method based on convex polygon subdivision

Abstract

The invention discloses a ground-to-air coverage scenarized beam generation method based on convex polygon subdivision. The method comprises the following steps of: obtaining a base station position set by adopting a universal ink Karl projection mode; constructing a three-dimensional low-altitude signal coverage area; performing convex polygon subdivision on the to-be-covered area; and generating beam configuration of each base station. According to the invention, the generation of the beam configuration of the base station in the three-dimensional low-altitude signal coverage area is realized, and the problem that the coverage of the three-dimensional area cannot be realized by the existing 17 kinds of scene beams is solved; and the beam configuration is obtained on the basis that the optimization target is that the overlapping rate of each prism area is minimum under the condition that the coverage rate is larger than or equal to R, and R belongs to (0, 0.99). The problem that network state information and the beam configuration are not matched due to dynamic adjustment of the beam configuration is solved, the beam configuration generated by the method does not need to obtain the number of users in real time to adjust the beam, and the covering capability is relatively good.

Description

technical field [0001] The present invention belongs to the technical field of communication, and further relates to a scene-based beam forming method for ground-to-space coverage based on convex polygon subdivision in the technical field of wireless communication. The present invention can be used to solve the problem of generating beam configurations of each base station sector on the ground in the low-altitude coverage scenario of ground base stations. Background technique [0002] Combined with the current common 5G network application scenarios, the service demand of users in low- and medium-altitude areas has increased significantly, such as high-rise building users or aerial drone terminals, but the vertical coverage of traditional base station antennas is limited, resulting in signal coverage for low- and medium-altitude users. Poor, but the 5G Massive MIMO antenna considers the planning of the vertical dimension in addition to the planning of the horizontal dimensio...

[0005] The purpose of the present invention is to address the deficiencies of the above-mentioned prior art, and propose a scenario-based beamforming method for ground-to-space coverage based on convex polygonal subdivision, which is used to solve the problem of antenna beam formation in scenarios where ground-to-space coverage cannot be achieved in the prior art. The generation of SSB beams and the problem that the existing SSB beam configuration cannot effectively improve coverage and improve user perception

Secondly, the beam configuration of each base station in the present invention is based on the optimization goal that the overlapping rate of each prism area is the minimum under the condition that the coverage rate is greater than or equal to R, and the beam configuration will not change after the beam configuration, R∈(0,0.99] , so that the present invention solves the problem that the traditional SSB beam optimization method needs to dynamically adjust the beam configuration of the SSB to cause the mismatch between the network status information and the beam configuration, and at the same time, the generated beam configuration has better coverage, which can greatly improve user Sensitivity
