Insufficient problem, the method of using LTE (Long Term Evolution) technology to realize the communication capacity for users by using unlicensed spectrum, so as to provide users with unlicensed spectrum resources to improve the quality of service of users, this method is It is called U-LTE (Unlicensed LTE). When U-LTE is implemented, the operator first needs to establish a U-LTE cell. Since the unlicensed spectrum is free and free to use, any person or any organization can use these spectrum resources. Therefore, in order to achieve fair sharing of unlicensed spectrum, U- LTE needs to listen to the channel of the unlicensed spectrum before sending data through the unlicensed spectrum.
