A wireless communication system is comprised of multiple radio access networks-RANs-which at least partly share the same frequency spectrum. Each RAN is provided with a gateway-GW-(GW1, GW2, GW3) for managing the network. Spectrum sharing in the system is achieved through a hierarchy of processes including long-term-LT-spectrum assignment, short-term-ST-spectrum assignment, and dynamic channel allocation, the latter process assigning sub-channels to base stations (BS1, . . . BS5; BS6, . . . BS10; BS11, . . . BS16) in each RAN. However, so-called "red" sub-channels (subject to interference) are liable to arise.
