Abstract
A first spectrum management apparatus that includes circuitry that acquires spectrum utilization information, determines a probability of getting spectrum resources, determines, based on the probability, adjusted spectrum sensing parameters to be used by the first wireless communication system, the adjusted spectrum sensing parameters including an energy detection threshold for spectrum sensing, transmits, to the first wireless communication system, an instruction to change original spectrum sensing parameters of the first wireless communication system to the adjusted spectrum sensing parameters, receives, from a second spectrum management apparatus that manages a second wireless communication system, spectrum sensing parameters changing feedback indicating that the second wireless communication system has been influenced by the first wireless communication system using the adjusted spectrum sensing parameters, and transmits, to the first wireless communication system, another instruction to change the adjusted spectrum sensing parameters back to the original spectrum sensing parameters.
