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 licensed users and their compliant devices.
