Abstract

The present invention provides a wireless network expansion method and device, the method comprising: grid-dividing the target area covered by the macrocellular network to obtain multiple grids; determining N first grids from the multiple grids grid, wherein deploying a micro base station in each of the first grids can maximize the network gain corresponding to the target area, so that deploying a micro base station in each of the N first grids The micro base station maximizes the network capacity of the target area. By determining N first grids from multiple grids for deploying the micro base station based on the network gain, the network gain corresponding to the target area can be maximized, and the network capacity can be optimized while meeting the coverage requirement.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method and equipment for expanding the capacity of a wireless network. Background technique [0002] With the continuous enrichment of mobile service types, the demand for service transmission rate continues to increase, and the wireless network needs to be continuously expanded to meet the increasing demand. Due to the limited spectrum resources available, the most effective means of network expansion is to deploy microcell base stations or picocell base stations (hereinafter referred to as microcell base stations) on the basis of existing macrocell base stations (hereinafter referred to as macrocell base stations). Spectrum multiplexing to improve network capacity. [0003] How to deploy and configure multiple micro base stations on the basis of the existing macro cellular network to form a heterogeneous network composed of multiple macro base stat...
