Abstract:
Various examples provide a method and a system for spectrum handover in cognitive radio (CR) systems. According to the method, after detecting a user of an authorized system appears at a current working frequency, the base station generates a spectrum handover command and sends the spectrum handover command via a channel identified by the CR DWNDI to instruct the UEs in the cell to perform spectrum handover according to the spectrum handover command.
