technical field

Background technique

Radio spectrum resources are a kind of limited and non-renewable natural resources. Therefore, countries have special management agencies for radio spectrum and issue special policies and regulations to achieve unified planning and management of radio spectrum. At present, most of the spectrum management in various countries adopts a fixed spectrum allocation strategy, that is, the spectrum resources are managed by government authorities and allocated to fixed authorized users, which can ensure that users avoid excessive mutual interference and make better use of spectrum resources. At present, spectrum resources can be divided into two categories, namely licensed spectrum (Licensed Spectrum) and unlicensed spectrum (Unlicensed Spectrum).

Licensed spectrum is strictly restricted and protected, allowing access only to authorized users and their compliant devices.

Unlicensed frequency bands are rich in resources, but in order to ensure fair coexistence between different radio access technologies (RATs) using this frequency band, a listen-before-talk (CCA)-based approach is introduced. Listen before talk, LBT) technology, the introduction of LBT into the unlicensed frequency band New Radio Interface (New Radio Based Unlicensed Access, NR-U) is an important way to ensure fair coexistence.
