- Radio spectrum resources are a limited and non-renewable natural resource. Therefore, countries have special management agencies for radio spectrum, and they have issued specific policies and regulations to achieve unified planning and management of radio spectrum.
- most countries' spectrum management adopts a fixed spectrum allocation strategy, that is, spectrum resources are managed by government authorities and allocated to fixed authorized users. This can ensure that each user avoids excessive mutual interference and makes better use of spectrum resources.
- the authorized spectrum is strictly restricted and protected, allowing only authorized users and devices that meet the specifications to access, and users usually have to pay for this.
- important departments such as public security, railway, civil aviation, radio, television, and telecommunications all have certain authorized spectrum.
- the communication of equipment in these departments is running on their authorized spectrum, especially in the telecommunications industry.
- the mobile phones we use every day are operated through In order to communicate with authorized spectrum owned by operators, all major operators have dedicated frequency bands authorized by the radio management units or departments of their respective countries to protect public mobile communications from interference.
- Non-licensed spectrum is a spectrum that can be accessed and used by devices that meet certain specifications and standards, but it must be guaranteed not to cause interference to other users. More typically, wireless fidelity (Wi-Fi), Bluetooth (BT) and other communication technologies are transmitted through unlicensed spectrum.

- LBT Listen Fore Talk
- cellular mobile communication technologies want to work normally on unlicensed frequency bands, they also need to follow the LBT mechanism. Therefore, in the process of data transmission on the unlicensed frequency band based on the cellular mobile communication technology, the base station needs to occupy the unlicensed frequency band before communicating with the terminal, which limits the timing of the base station sending a wake-up signal to the terminal.
- the base station in the process of using the unlicensed frequency band based on the cellular mobile communication technology, the base station sends a wake-up signal at a certain time-domain location before the start of the paging moment (Paging) in a paging radio frame
- Paging paging moment
- the terminal thinks that there is no service transmission, so it does not detect control information such as paging information, resulting in data
- the transmission delay becomes larger.
