Problems solved by technology

However, there is almost no spectrum and load switching between various wireless access technologies in the existing communication network, that is, there is almost no cooperative operation with each other, which leads to relatively fixed and inflexible spectrum usage, which reduces the spectrum utilization rate, that is, some wireless access technologies The spectrum load of one technology is relatively light, and the spectrum load of another wireless access technology is heavy, but because there is no interaction and cooperation between access technologies, flexible and dynamic spectrum allocation cannot be achieved

Abstract

The invention discloses a frequency spectrum reallocation method and device capable of increasing the utilization ratio of a frequency spectrum. The frequency spectrum reallocation method comprises the following steps of: acquiring frequency spectrum occupation situation information of adjacent group domains by the current target group domain, and calculating a reallocable frequency spectrum of the target group domain according to the frequency spectrum occupation situation information of the adjacent group domains; and during frequency spectrum reallocation, selecting a frequency spectrum subset from the reallocable frequency spectrum to be allocated to a working cell in the target group domain. The frequency spectrum reallocation method and device are applicable to a reallocable wireless communication system and can be used for reallocating frequency spectrums capable of being transferred in the adjacent group domains to a target frequency spectrum, so that the utilization ratio of the frequency spectrum can be increased, and better experience of a user is guaranteed. Meanwhile, the method is lower in complexity and easy to realize.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a spectrum reconfiguration method and device for a reconfigurable system. Background technique [0002] Spectrum resource is the basic medium of communication, and the spectrum resource is very limited, which makes people want to maximize the spectrum utilization. The development of different wireless access technologies is also to improve spectrum utilization. However, there is almost no spectrum and load switching between various wireless access technologies in the existing communication network, that is, there is almost no cooperative operation with each other, which leads to relatively fixed and inflexible spectrum usage, which reduces the spectrum utilization rate, that is, some wireless access technologies The spectrum load of one radio access technology is relatively light, and the spectrum load of another wireless access technology is heavy. However, since there is ...
