Method and device for channel selection

Abstract

The invention discloses a channel selection method and a corresponding device. The method comprises the steps of calculating a use ratio of a station of a wireless communication system using a current channel, judging whether the station needs to select a channel again or not according to the use ratio, selecting a new channel meeting a specific condition from channels shared by the station and other stations when the judge result is yes, wherein the specific condition comprises that the predicted use ratio of the new channel used by the station is higher than the use ratio of the current channel. The method selects a new channel meeting the specific condition from the channels shared by the station and other stations, the predicted use ratio of the new channel used by the station is higher than the use ratio of the current channel, and therefore the problem that the mutual interference occurs when a plurality of stations of the wireless communication system share the multiple channels is solved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a channel selection method and device. Background technique [0002] In recent years, with the widespread use of various wireless communication devices such as smartphones and tablet computers, the demand for wireless data communication has been increasing. However, the licensed spectrum required for wireless communication is limited. Therefore, an emerging communication technology—3GPP (The 3rd Generation Partnership Project, 3rd Generation Partnership Project) intends to deploy an LTE (Long Term Evolution, Long Term Evolution) system in a license-free spectrum. Due to the openness of the license-exempt spectrum, it can be used by many wireless communication systems at the same time, so how to realize channel sharing by many wireless communication systems on the license-free spectrum. Sharing here means that stations of multiple wireless communication syste...

AI Technical Summary

Problems solved by technology

This dynamic sharing method can well solve the problem that multiple LTE system sites share a single channel, but when multiple LTE system sites share multiple channels, how to back off time to avoid interference between sites in the wireless communication system is not clear. give a solution

[0008] Therefore, the inventor provides a method to solve the problem of mutual interference when multiple wireless communication system sites share multiple channels on the basis of research on existing communication technologies.
