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: Techniques are provided for temporarily allocating a new radio controlled by a spectrum access system (SAS) a frequency spectrum in shared spectrum in which to transmit, and a maximum transmit power level. The temporary frequency spectrum and optionally maximum transmit power level may be sent to the new radio so that it can commence transmitting prior to a planned, e.g., periodic, spectrum coordination is performed for all radios which had requested authorization from the SAS to transmit in the shared spectrum.

Abstract: Techniques for modelling a radio network in a geographic region utilizing shared spectra are disclosed. Population data is obtained for the geographic region. A number of radios per channel in the geographic region, N′, is determined. Candidate geographic location for radios in the geographic region are determined. For every channel in the shared spectra, at least one of a static dataset and a dynamic dataset is determined. At least one set of output data, that is a statistical characterization of the radio network, is generated using at least one of the static dataset and the dynamic dataset, to aid in design of the radio network.

Abstract: A computing device includes a processor and memory storing instructions that are executable to determine a median of a first mixture distribution. The instructions are also executable to determine a parent mean, a parent standard deviation, and boundaries for each of multiple segments in the first mixture distribution. The instructions are also executable to determine a segment mean and a segment second moment for each segment based on the parent mean, the parent standard deviation, and the boundaries for the respective segment. The instructions are also executable to determine a scaled probability for each segment. The instructions are also executable to determine a mixture mean and a mixture standard deviation for the first mixture distribution based on the segment mean, the segment second moment, and the scaled probability for each segment in the first mixture distribution.
