Description

Unauthorized channel detection method, device, equipment and storage medium

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for detecting an unlicensed channel.

Background

Radio spectrum resources are limited and non-renewable natural resources, so that each country has a special regulatory agency for radio spectrum, and a special policy and regulation is issued to realize the unified planning and management of radio spectrum. At present, most of the frequency spectrum management of each country adopts a fixed frequency spectrum allocation strategy, namely, frequency spectrum resources are managed by government authorities and allocated to fixed authorized users, so that excessive mutual interference among the users can be avoided, and the frequency spectrum resources are better utilized. Currently, spectrum resources can be divided into two categories, i.e., licensed Spectrum (Licensed Spectrum) and Unlicensed Spectrum (Unlicensed Spectrum).

The licensed spectrum is severely restricted and protected, allowing access only to authorized users and their compliant devices.

The Unlicensed frequency band has rich resources, but in order to ensure fair coexistence between different Radio Access Technologies (RATs) using the frequency band, a Listen Before Talk (LBT) Technology Based on CCA (Clear Channel association) is introduced, and introducing LBT into a New Radio Based Unlicensed Access (NR-U) of the Unlicensed frequency band is an important way to ensure fair coexistence.
