1. An electronic device for spectrum management, comprising:
a transceiver;
a memory; and
processing circuitry configured to:
perform control to operate as a first spectrum management node that performs distributed spectrum management with a second spectrum management node,
wherein the distributed spectrum management comprises:
exchanging initial spectrum supply-and-demand information with the second spectrum management node,
wherein the initial spectrum supply-and-demand information is related to a spectrum supply-and-demand of at least one first wireless network management node managed by the first spectrum management node and at least one second wireless network managed by the second spectrum management node,
wherein the initial spectrum supply-and-demand information is stored in the memory in a form of blockchain,
wherein, in the exchanging of the initial spectrum supply-and-demand information, the electronic device is configured to take specific actions as follows:
upon determining a case where a plurality pieces of new spectrum allocation information are received within a specific period of time, the processing circuitry is configured to select one of the plurality pieces of new spectrum allocation information having an earliest publication time therefrom to perform at least one of the spectrum assignments based on the selected one of the plurality pieces of new spectrum allocation information received within the specific period of time,
upon determining a case where a plurality pieces of new spectrum allocation information having a same block serial number are received, the processing circuitry is configured to select one of the plurality pieces of new spectrum allocation information having an earliest publication time therefrom to perform at least one of the spectrum assignments based on the selected one of the plurality pieces of new spectrum allocation information having the same block serial number,
upon determining a case where a time window identifier of received new spectrum allocation information is not continuous with a time window identifier of currently stored spectrum allocation information, the processing circuitry is configured to send a request for performing information synchronization to the second spectrum management node,
upon determining a case where a block serial number of received new spectrum allocation information is not continuous with a serial number of a currently stored blockchain, the processing circuitry is configured to send a request for performing information synchronization to the first spectrum management node,
upon determining a case where a predetermined number of pieces of spectrum allocation information are stored, the processing circuitry is configured to notify a spectrum allocation indicated by spectrum allocation information preceding the predetermined number of pieces of spectrum allocation information to each of the first wireless network management node and the second wireless network management node, or
upon determining a case where a predetermined number of blocks are stored, the processing circuitry is configured to notify a spectrum allocation indicated by a block preceding the predetermined number of blocks to each of the first wireless network management node and the second wireless network management node.
