Abstract

The invention provides a soft frequency reusing method and device based on a cognitive technology and a base station. The method comprises the following steps of: configuring frequency points to be distributed in a cell as a preferable frequency point set and configuring distributed frequency points of a neighboring cell of the cell as an optional frequency point set; judging whether resources which can be distributed exists in the preferable frequency point set or not; if so, distributing the frequency points in the preferable frequency point set to a mobile terminal; otherwise, distributing the frequency points in the optional frequency point set to the mobile terminal. through adoption of the soft frequency reusing method and device based on the cognitive technology and the base station, provided by the invention, a concept of a center and edges of the cell is broken through, the current frequency points of a user are sequenced through judging neighboring cell measurement information reported by the user and the frequency points with low same frequency interference are selected for access, therefore the same frequency interference is assured, and higher frequency utilization rate is realized.

Description

technical field

[0001] The present invention relates to the field of wireless communication, in particular to a soft frequency multiplexing method based on cognitive technology, a soft frequency device based on cognitive technology and a base station. Background technique

[0002] As we all know, the spectrum resources of wireless communication networks are always limited, while the bandwidth requirements of users are constantly increasing. Because of this, frequency reuse has become a means to use "limited" spectrum resources to solve the problem of "infinite" capacity. The traditional method of frequency reuse, as shown in Figure 1(a), takes the cell as the unit and maintains a certain distance between the same-frequency cells to resist the same-frequency interference. The distance between the same-frequency cells determines the frequency utilization rate. High and low; when the capacity demand increases, as shown in Figure 1(b), the cell radius decreases and the frequenc...
