Embodiment Construction
[0044] In the embodiment of the present invention, the authorized system signal on the shared frequency band is detected according to the characteristic symbol of the authorized system signal; within the first preset time period, the relevant information that there is no authorized system signal on the shared frequency band is recorded; according to the recording result, in the above When there is no licensed system signal on the shared frequency band, notify the base station of the method of switching the frequency point of the unlicensed system. Adopting the technical scheme of the present invention can effectively improve the spectrum utilization rate, and perform frequency point switching on the unlicensed system very accurately, improve the reliability of the frequency point switching, and avoid the problem of frequent frequency point switching of the unlicensed system caused by misjudgment .
[0045] Preferred embodiments of the present invention will be described in det...

The present invention discloses a spectrum sharing method and device, which are used to solve the problem in the prior art that when multiple systems share the spectrum resources of the same frequency band, there is a misjudgment of the frequency point switching cycle, and frequent frequency point switching causes system reliability. low problem. The method is as follows: detect the authorized system signal on the shared frequency band according to the characteristic symbol of the authorized system signal; record the relevant information that the authorized system signal does not exist on the shared frequency band within the first preset time period; When there is no licensed system signal, the base station is notified to switch the frequency point of the unlicensed system. By adopting the technical scheme of the invention, the frequency point switching of the unlicensed system can be performed very accurately, the reliability of the frequency point switching and the spectrum utilization rate are improved, and the problem of frequent frequency point switching of the unlicensed system caused by misjudgment is avoided.
Description
technical field [0001] The present invention relates to the communication field, in particular to a spectrum sharing method and device. Background technique [0002] The wireless communication system is used to transmit wireless signals and realize information interaction between various terminals, which plays a very important role in daily life and industrial production. As the demand for spectrum resources in wireless communication systems continues to increase, the spectrum resources of wireless communication systems are decreasing day by day. As a non-renewable resource, once occupied by a certain communication system, spectrum resources cannot be regenerated. According to survey and research data, the utilization rate of spectrum resources varies according to different conditions such as regions, time periods, and frequency bands. The utilization rate is low, so there is a very serious waste phenomenon. In order to solve the contradiction between the spectrum resource...
