Claim 11:
12. A spectrum division device in a wireless communication system, comprising:
processing circuitry configured to send spectrum resource request to a spectrum coordination device in a first coexistence system that includes the spectrum division device and one or more secondary systems divided into coexistence groups, the wireless communication system comprising the first coexistence system and a second coexistence system comprising one or more secondary systems,
determine whether transmission power of the one or more secondary systems in the coexistence groups managed by the spectrum division device satisfies a coexistence management requirement of the first coexistence systems, and
send, in a case where the transmission power of the one or more secondary systems do not satisfy the coexistence management requirement of the first coexistence system, a spectrum usage report to the spectrum coordination device, the spectrum coordination device generating spectrum modification information for modifying spectrum resource of at least one of the secondary systems in the first coexistence system and/or for modifying spectrum resource of at least one of the secondary systems in the second coexistence system to maximize continuity of the spectrum resources of the first coexistence system.
