    Abstract: A system for ESC protection includes a spectrum access system (SAS) configured to allocate a frequency band in the system and at least one Citizens Broadband Radio Service device (CBSD) communicatively coupled to the SAS and configured to provide wireless service to UEs. The system also includes at least one ESC communicatively coupled to the SAS and configured to detect RADAR signals from offshore RADAR devices. The SAS is configured to assign grants to the at least one CBSD such that the aggregate signal energy received at the ESC does not cross an overload threshold, as calculated by the SAS. The ESC is configured to detect an aggregate signal energy received at the ESC, and trigger, in response to the aggregate signal energy exceeding the overload threshold, an operation that suspends transmission of at least one CBSD or moves at least one CBSD to a different frequency channel.

    Abstract: A method for selecting at least one channel for a network element in a shared spectrum communication system is provided. The method includes identifying a plurality of candidate channels of a frequency band of the shared spectrum communication system. For each channel of the plurality of channels, the method further includes: evaluating the channel based on one or more of a plurality of criteria for the network element; scoring the channel based on the evaluation of the channel for the network element; and ranking the plurality of candidate channels based on the assigned scores for each of the plurality of channels. The method further includes selecting at least one channel based on the ranking of the plurality of candidate channels.

    Abstract: Systems and methods for SAS interference calculation management are provided. In one embodiment, a system comprises: a processor coupled to a memory; a network interface configured to couple the SAS to a network, the processor coupled to the interface; and a grant request processing function executed by the processor, the grant request processing function processes grant requests received from radios located in a neighborhood defined around a protection area, wherein the requests comprises a request to transmit on a protected frequency channel of the protected area; wherein the grant request processing function manages a timing of when to processes interference calculations associated with the grant requests based on or both of: determining whether to steer a requesting radio to a non-protected frequency channel; and at least one Q/N estimate power calculation, wherein Q comprises a value of an allowed interference power limit, and N is a number of authorized radios.

    Abstract: A method is provided. The method comprises: selecting a new protection point in a dynamic protection area; creating an initial sort list of radios; determining look angles; determining which look angle includes most radios in its main beam; determining a modified sort list and an initial move list for the determined look angle; determining a certain percentile of aggregate interference power spectral density at the new protection point for radios that are in a main beam for each of remaining look angles; sorting, by level of certain percentile of aggregate interference power spectral density, the remaining look angles; and generating a move list of radios.
