Abstract

The embodiment of the invention provides a network capacity improving method and device based on an electromagnetic map. The method comprises the steps that the position of each terminal in all terminals in the dense network is acquired, the dense network comprises a plurality of virtual cells, and each virtual cell comprises a terminal and a plurality of base stations with the terminal as the center; slow-varying channel state information corresponding to each terminal is obtained according to the position of each terminal and a preset electromagnetic map; the electromagnetic map records a preset corresponding relationship between different terminal positions obtained in advance and slow-varying channel state information; and a sending signal matrix of the virtual cell where each terminalis located is correspondingly obtained according to the slow-varying channel state information corresponding to each terminal. According to the embodiment of the invention, the complexity of networkcapacity improvement is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for increasing network capacity based on an electromagnetic map. Background technique [0002] With the continuous growth of user demands, the future mobile communication network needs to provide higher and higher service capacity. At present, the fifth-generation mobile communication network is being built in full swing around the world, among which increasing network density, millimeter wave communication and massive multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO) technology are important technical points. [0003] Specifically, in practical applications, the special difficulty faced in building a dense communication network is site constraints. Constrained by geographical conditions and human factors, dense communication networks often cannot be fully deployed according to the rules of the cellular ...
