Abstract
Dynamic frequency planning of shared spectrum is contemplated. The sharing may facilitate use of unlicensed or non-exclusively licensed spectrum within a geographical area serviced by two or more spectrum access sharing systems (SASs) or otherwise subjected to control of independently operating entities.
Claims20
A non-transitory computer-readable medium having a plurality of instructions executable with a processor of a controller to facilitate dynamic frequency planning, the plurality of instructions being sufficient for:
- determining a first one or more devices and a second one or more devices to be respectively associated with a first spectrum access sharing system (SAS) and a second SAS;
- generating a shared solution as a function of operating characteristics provided from the first and second SASs respectively for the first and second one or more devices, the shared solution defining the operating characteristics for the first and second one or more devices to be used thereafter to control frequency usage within the shared spectrum in a manner sufficient to avoid or minimize interference;
- processing a first optimization file transmitted from the first SAS, the first optimization file including information specifying the operating characteristics for the first one or more devices;
- processing a second optimization file transmitted from the second SAS, the second optimization file including information specifying the operating characteristics for the second one or more devices;
- and
- generating the shared solution as a function of the first and second optimization files.
A system for frequency planning of shared spectrum, the system comprising:
- a first spectrum access sharing system (SAS) facilitating wireless signaling with a first one or more devices over a shared spectrum, the first SAS overlapping with a second SAS facilitating wireless signaling with a second one or more devices over the shared spectrum;
- a controller in communication with the first and second SASs for generating a shared solution as a function of operating characteristics provided therefrom for the first and second one or more devices, the shared solution setting the operating characteristics for the first and second one or more devices to be used thereafter in controlling frequency usage within the shared spectrum;
- and
- wherein the controller converges a first matrix, a second matrix and an updated matrix to generate a shared matrix, the shared matrix defining the operating characteristics for the shared solution, the first matrix being provided from the first SAS to represent the operating characteristics for the first one or more devices, the second matrix being provided from the second SAS to represent the operating characteristics for the second one or more devices, the updated matrix being provided from one of the first and second SASs to include proposed changes to one of the first and second matrices necessary to avoid frequency interference.
A method for dynamic frequency planning comprising:
- determining a first one or more devices and a second one or more devices to be respectively associated with a first spectrum access sharing system (SAS) and a second SAS;
- generating a shared solution as a function of operating characteristics provided from the first and second SASs respectively for the first and second one or more devices, the shared solution defining the operating characteristics for the first and second one or more devices to be used thereafter to control frequency usage within the shared spectrum in a manner sufficient to avoid or minimize interference;
- processing a first optimization file transmitted from the first SAS, the first optimization file including information specifying the operating characteristics for the first one or more devices;
- processing a second optimization file transmitted from the second SAS, the second optimization file including information specifying the operating characteristics for the second one or more devices;
- and
- generating the shared solution as a function of the first and second optimization files.
The method of 16 further comprising generating the shared solution from processing files having the first, second and updated optimization information.
