A method for enhancing network coverage based on adaptive generation of resource cell. A traditional cell in a network is taken as an initial state of the network. A correlation matrix in a current network state is generated. Whether |ω−ω|/ω>ε is determined. Each access point is divided into a plurality of resource cells. A CU-DU network mapping table is generated. A middlehaul link of each of the plurality of resource cells is constructed according to the CU-DU network mapping table.

Method for enhancing network coverage based on adaptive generation of resource cell

A scene-based beam generation method for ground-to-air coverage based on convex polygon subdivision is provided and includes: obtaining a collection of base station positions by using a method of universal transverse mercator projection; constructing a three-dimensional (3D) low altitude signal coverage area; performing convex polygon subdivision on the area to be covered; and generating a beam configuration of each base station. The method realizes generation of beam configurations of base stations in the 3D low altitude signal coverage area, overcomes a problem that the existing 17 kind of scene-based beams cannot realize the coverage of 3D area, overcomes a problem of mismatch between network state information and beam configuration caused by dynamic adjustment of beam configurations. The beam configurations generated by the method does not need to obtain the number of users in real time to adjust the beam, and has a good coverage ability.
