Problems solved by technology
When the base station is in the working state, the same frequency point cannot transmit and receive at the same time at the same time. If the base station regularly monitors the interference of the working frequency point, it will undoubtedly reduce the transmission time of the base station, thereby reducing the system efficiency.

Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0025] In the embodiment of the present invention, a method for selecting a frequency point in an LTE system is proposed. The base station determines the interference value of the server terminal in the cell at a certain moment. If it is less than the first threshold value, the base station continues to work at the current frequency point; otherwise, it performs different frequency Detect, determine the frequency point with the lowest received power, and determine whether to switch the frequency point to work according to the difference between the current operating frequency point and the frequency point with the lowest received power, which can effectively use frequency resources and improve system efficiency.
[0026] The base station...

The invention discloses a frequency point selection method. The method comprises the following steps that: a base station determines the interference value of a server terminal of a cell at a certain moment, and continues to work at a current frequency point if the interference value is smaller than a first threshold value; and if the interference value is not smaller than the first threshold value, the base station performs pilot frequency detection, determines a frequency point with lowest receiving power, and determines whether to switch to another frequency point for working according to a difference value between the current working frequency point and the frequency point with the lowest receiving power. Based on the same invention concept, the invention also provides a device. The frequency resources can be effectively utilized, and the system efficiency is increased.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a frequency point selection method and device. Background technique [0002] With the continuous development of wireless broadband technology, the spectrum resources available for wireless systems are becoming more and more abundant, and broadband systems exceeding 100M have become the development trend of wireless communication systems. [0003] When a system with multiple base stations and multiple users performs broadband networking over 100M, in order to effectively use frequency resources, the selection of frequency points is very important. [0004] For base stations and users, limited by radio frequency and base station processing capabilities, the best choice is often that each base station chooses one frequency point for transmission or transmission, and different base stations choose different frequency points, so as to effectively avoid interference betw...
