Embodiment Construction
[0030] The basic idea of the present invention is: the secondary wireless communication system senses according to the sensing period indicated by the high-level node; the high-level node receives the sensing measurement result of the secondary wireless communication system, evaluates the channel occupancy, and obtains the sensing result and the prediction result.
[0031] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.
[0032] figure 1 It is a schematic flow chart of a multi-node joint spectrum sensing method in the present invention, such as figure 1 As shown, the method includes the following steps:
[0033] Step 101, the secondary wireless communication system performs sensing according to the sensing cycle indicated by the high-level node;
[0034] Specifically, the secondary wireless communication system includes at least secondary base stations and secondary us...
