Managing resources in CBRS networks
Systems, methods, and computer-readable media for improving resource management in Citizens Broadband Radio Service (CBRS) networks include a Spectrum Access System (SAS) in coordination with one or more CBRS devices (CBSDs) and a Digital Network Architecture center (DNA-C). Resource allocation decisions can be based on one or more policies such as a priority, a preemption capability index and/or a preemption vulnerability index associated with the CBSDs. Resource allocation can also be based on inter-access point (AP) coordination between two or more CBSDs and comparative performance indicators of the two or more CBSDs. Managing interference between two or more groups of CBSDs can be based on the inter-AP coordination and group identifiers associated with the two or more groups. Bandwidth allocation can be modified to the two or more CBSDs and seamless transition can be implemented using timers.

9. The CBSD of claim 7 , where the at least one non-transitory computer-readable medium further comprising instructions which, when executed by the one or more processors, cause the one or more processors to:
receive a time interval for a seamless transition from a current channel to a new channel for the CBSD; and
receive one or more time instances associated with the time interval.
10. The CBSD of claim 7 , the at least one non-transitory computer-readable medium further comprising instructions which, when executed by the one or more processors, cause the one or more processors to:
determine one or more physical cell identifiers (PCIs) of one or more cells associated with the CBSD and one or more neighboring CBSDs; and
provide the one or more PCIs to the SAS.
11. The CBSD of claim 7 , wherein the one or more parameters comprising at least one of a frequency range in one or more channels or a maximum transmit Effective Isotropic Radiated Power (EIRP); and the at least one non-transitory computer-readable medium further comprising instructions which, when executed by the one or more processors, cause the one or more processors to:
determine resources for the one or more CBRS UEs based on the one or more parameters.
12. The CBSD of claim 7 , wherein the one or more policies are received from at least one of a Digital Network Architecture Center (DNA-C) or a network controller.
13. A non-transitory computer-readable medium comprising instructions which, when executed by one or more processors, cause the one or more processors to:
