Background technique

Wireless spectrum resources are the basis of modern mobile communication technology. With the popularization of mobile terminal devices such as smartphones and tablet computers, the demand for spectrum for mobile communication is increasing. On the one hand, the total amount of available spectrum resources is limited, especially in the low and medium frequency bands The number of spectrum resources is less. On the other hand, due to the influence of factors such as the evolution process between systems and regional load differences, there is a lot of waste of spectrum resources in the early wireless communication system, which is manifested in the following aspects: the evolution of wireless communication systems has 2G, 3G, 4G and 5G communication standards coexist. Operators usually deploy one or more communication systems. Each system has its own spectrum range. After deployment, the spectrum is basically fixed. For example, in the actual application process of the 2G system, only a small part of the wireless spectrum may be used according to different regions. In the process of the evolution of the wireless communication system, there is still a margin for the users of the old system, while there are fewer users of the new system. The systems need to be deployed at the same time, respectively occupying spectrum resources and causing spectrum waste.

For another example, there are tides in different services of mobile users, such as more voice services and less data services during working hours in business districts, and more data services and less voice services during off-duty hours. This phenomenon of service tides also requires timely adjustment of the frequency spectrum to avoid the frequency spectrum. waste of resources. Therefore, how to improve the utilization rate of wireless spectrum resources is an urgent problem to be solved at present.
