Problems solved by technology

[0003] The main disadvantage of the above-mentioned traditional frequency reuse method is that the frequency reuse is based on the cell, and the interference situation in different areas inside the cell is different. However, this method can only determine the reuse distance according to the worst case (usually the edge of the cell)
However, the above two methods can only make a rough judgment, and cannot accurately define the inner and outer circles;
[0007] 2. The choice of frequency reuse scheme is too single, usually it is either one or the other. The frequency band allocation is similar to the concept of "concentric circles", and there are only two options of "inner circle" and "outer circle".
And for the outer circle area, that is, the edge area of ​​the cell, it cannot be further subdivided
For example, although the frequency resources of the adjacent cell on the right side of a certain cell cannot be reused in the "right side of the outer circle" of the cell, they can actually be reused in the "left side of the outer circle". However, conventional soft frequency reuse There is no way to do this with the method

Embodiment Construction

[0027] The invention provides a soft frequency multiplexing method, device and base station based on cognitive technology, which can solve the problem of low frequency utilization in the prior art. Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] A soft frequency multiplexing method based on cognitive technology, such as image 3 shown, including the following steps:

[0029] Configure the frequency points to be allocated in the cell as the preferred frequency point set, and configure the allocated frequency points in the adjacent cells of the cell as the optional frequency point set;

[0030] judging whether there are resources available for allocation in the preferred frequency point set;

[0031] If yes, allocating the frequency points in the preferred frequency point set to the mobile terminal;

[0032] If not, allocate the frequency points in the set of optional frequency points to t...

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...
