Abstract

The present invention discloses a resource allocation method and device, which are used to solve the problem that in the prior art, when resources are allocated to cell edge users, the allocated frequency band resources are discontinuous, resulting in waste of edge frequency band resources, decreased spectrum efficiency, and edge frequency band resources. Technical issues with poor user experience. The method is: obtain the first edge frequency band resources required by the edge users of the serving cell; obtain the adjacent cell interference information corresponding to the serving cell, and obtain M edge frequency band resources corresponding to the serving cell based on the adjacent cell interference information The second edge frequency band resources available in the block; based on the first edge frequency band resources and the second edge frequency band resources, perform continuous processing on the edge frequency band resources of the serving cell, and determine the edge frequency band resources allocated to the edge users frequency band resource.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a resource allocation method and device. Background technique [0002] With the continuous development of science and technology, LTE (Long Term Evolution, Long Term Evolution) wireless technology has been widely used. LTE downlink adopts orthogonal frequency division multiplexing technology to modulate high-speed data to each orthogonal sub-channel, which can effectively reduce interference between channels. However, this kind of orthogonal channel is only limited to the users in the current cell, and there will be interference between users in different cells, especially for the edge users of the same frequency network cell, the interference is very serious. Therefore, ICIC (Inter-cell Interference Coordination, inter-cell interference coordination) technology can reduce the interference between cells of the same frequency, improve the spectrum efficiency of c...
