1. A spectrum coordination device in a wireless communication system, comprising:
processing circuitry configured to
receive spectrum resource request from a spectrum division device in a first coexistence system that includes the spectrum coordination 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 a coexistence management requirement of the first coexistence system is satisfied, and
generate, in a case where the coexistence management requirement of the first coexistence system is not satisfied, 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.
