1. A spectrum management apparatus comprising:
processing circuitry configured to:
determine an interference between at least two radio access networks of a coexistence system, each of the at least two radio access networks using different radio access technologies;
generate an interference overlap graph based on the determined interference;
allocate spectrum resources for the at least two radio access networks based on the interference overlap graph; and
a transceiver configured to transmit the interference overlap graph and the spectrum resources allocated for the at least two radio access networks to spectrum division apparatuses of the at least two radio access networks.
