1. A method for dynamic frequency planning of shared spectrum, the shared spectrum being utilized by a plurality of devices within an overlapping geographical area to facilitate wireless signaling, a first plurality of the plurality of devices being controlled with a first spectrum access sharing system (SAS) and a second plurality of the plurality of devices being controlled with a second SAS, the method comprising:

  • processing a first optimization matrix transmitted from the first SAS to the second SAS, the first optimization matrix representing operating characteristics for the first plurality of devices;

    processing an updated optimization matrix and a second optimization matrix transmitted from the second SAS, the updated optimization matrix including proposed changes to the first optimization matrix, the second optimization matrix representing operating characteristics for the second plurality of devices; and

    negotiating between the first SAS and the second SAS to converge the first, second and updated optimization matrices into a shared matrix, the shared matrix being sufficient for the first SAS and the second SAS to coordinate frequency usage within the shared spectrum for the first and second devices.
