Problems solved by technology

In addition, due to different detection methods, the accuracy of the detection results is also different. Usually, the accuracy of the upgraded detection method must be higher than before the upgrade. When BS is doing data analysis to determine whether there is an ATSC signal in the area, all CPE The detection report of the test report is processed in a unified way, so that the effect of the operator adding an upgraded CPE (CPE with an upgraded detection technology) is not obvious

Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] In the present invention, when the network side receives the perception detection report of the subordinate user equipment, according to the perception detection report of each user equipment and the perception ability of the user equipment, in the case of different perception capabilities, it pays more attention to the user equipment with strong perception ability According to different degrees of emphasis, comprehensively judge whether there is spectrum occupancy at present, so as to judge the perception detection report more accurately and improve the quality of judgment results.

[0043] The first embodiment of the present invention will be described below. This embodiment relates to a spectrum detection method in a wireless network, such as Figure 4 s...

Abstract

The invention relates to a wireless communication field, disclosing a frequency spectrum detection and sharing method, system, user equipment and device. In the invention, when the network receives at least two CPE sensing detection reports, whether frequency spectrum occupancy occurs or not currently can be judged synthetically according to the CPE sensing detection reports and CPE sensing capability, thereby performing the judgment of sensing detection reports more accurately and improving the quality of judgment result. The CPE sensing capability comprises CPE sensing detection method, forthe sensing detection report for sensing same type signal, the network distributes higher credibility for higher level sensing detection report according to the CPE sensing detection method, and judges the sensing detection reports comprehensively according to the credibility.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to spectrum detection technology. Background technique [0002] In recent years, with the rapid development and popularization of wireless technology, spectrum resources have become increasingly scarce. In order to solve this problem, some spectrum sharing systems have appeared at present. The characteristic of these systems is that their operating frequency bands do not require authorization. In the working frequency band, these license-free systems need to coexist with the licensed system (IU), and the temporarily idle frequency band can be used without affecting the normal operation of the licensed system. Since the working premise of the license-free system is that it cannot interfere with the normal operation of the licensed system, once the license-free system detects that the license-authorized system exists in a certain frequency band it is using, the license-free sys...
