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 .

The invention discloses a frequency spectrum sharing method and device, for solving the problem of poor system reliability caused by wrongly determined frequency point switching period and frequent frequency point switching when the frequency spectrum resources of the same frequency range are shared by multiple systems in the prior art. The method comprises: detecting authorization system signals over a common frequency range according to authorization system signal characteristic symbols; within a first preset time period, recording correlation information of the nonexistence of the authorization system signals over the common frequency range; and according to a recording result, informing a base station of performing frequency point switching on an unauthorized system when there are no authorization system signals over the common frequency range. By adopting the technical scheme provided by the invention, frequency point switching can be accurately performed on the unauthorized system, the frequency point switching reliability and the frequency spectrum utilization rate are improved, and the problem of frequent frequency point switching of the unauthorized system, caused by wrong determination, can be 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...
