FIELD: electrical communication engineering.
SUBSTANCE: invention relates to wireless communication. System that receives a request for resources from a first system of a plurality of systems having different levels of priority; identifies resources that are available in a second system different from the plurality of systems based on the received request; and determines whether to adjust a resource assigned to the plurality of systems based on the priority level of the first system and the resources that are available in the second system.
EFFECT: technical result is frequency spectrum management, wherein priority levels are divided for secondary systems coexisting with a primary system that compete with each other in a cognitive radio system.
