Embodiment Construction

[0012] The implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0013] A method for expanding the capacity of a wireless communication network of the present invention is to introduce the concept of "cellular" into the network construction, and use the method of cell splitting to achieve capacity expansion by means of spectrum multiplexing. The cellular splitting (cell splitting) is to split N≥1 sectors into 2*N sectors on the basis of the traditional 3 sectors according to the network requirements of the sectors; 2 split sub-sectors replace Existing sector; the sub-sector coincides with the critical coverage area of ​​the sector being replaced. The sub-sector is to split the sector covered by the radiation pattern of the existing sector into two regions defined by the independent radiation pattern of two deflected sub-sectors. The independent radiation patterns of the two sub-deflections are caused by the base stati...

Abstract

The invention discloses a capacity expansion method for a wireless communication network. N sectors are split into 2*N sectors according to network requirements of the sectors based on conventional three sectors, wherein N is more than or equal to 1; the conventional sectors are replaced by the split subsectors; the capacity is expanded by using spectrum reuse; and therefore, the interference caused by spectrum reuse in the capacity expansion of the wireless mobile communication network can be effectively solved so as to provide a new idea for the capacity expansion of the network. Compared with a cellular splitting mode, the method greatly saves the construction cost of the base station and reduces the cost of the capacity expansion of the network when used for expanding the capacity of the network.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for expanding the capacity of a wireless communication network and a multi-beam base station antenna. Background technique [0002] In today's wireless communication field, what is most lacking is spectrum resources. In order to effectively utilize limited spectrum resources, the concept of "cellular" is introduced in network construction. In order to cover a large area, the area is first divided into many small cellular areas, so that the same spectrum resources can be used in distant "cells", achieving the effect of spectrum reuse. [0003] With the increase of mobile users and call volume, network expansion has become urgent. The traditional expansion method is the so-called cell splitting (cell splitting), that is, to reduce the coverage area of ​​the existing "cell" and introduce a new "cell" in the newly generated coverage blind area. Therefore, the operato...
