Abstract: A natural language programming system may configure a machine learning (ML) model to translate natural language descriptions into constrained language statements. The constrained language statements may express the natural language descriptions using a constrained subset of natural language. The constrained subset of natural language includes words with unambiguous semantics and with meaning that has a clear and singular interpretation. The constrained language statements with unambiguous semantics enable construction of valid statements in high-level “English-like” executable programming language. With the present system, a user does not need to learn a new programming language but rather learn to constrain their natural language statements to a subset of the natural language (“constrained language”) and to generate executable programs.

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 for optimizing antenna parameters of a radio configured to transmit on spectrum shared by incumbent user(s) are disclosed. The incumbent user has priority to use the shared spectrum over the radio. The antenna parameters are optimized to reduce interference to incumbent user(s) and/or other radios utilizing the shared spectrum whilst maintaining satisfactory coverage area.

Abstract: Systems and methods for managing priority exceptions for shared spectrum radio services are provided. In one embodiment, a shared spectrum radio services system comprises: a spectrum access system (SAS) configured to adjust transmit power levels of one or more radios, wherein the one or more radios transmit on a protected frequency of a shared spectrum, wherein the SAS is associated with a protection area that comprises at least one dynamic incumbent RF system that transmits on the protected frequency; and wherein the SAS applies a standard transmit expiration time parameter to the one or more radios, the standard transmit expiration time parameter indicating a time of day at which authorization to transmit on the protected frequency expires; and wherein the SAS is configured to execute a transmit expiration parameter exception protocol to override the standard transmit expiration time parameter for at least one of the one or more radios.

Abstract: Techniques are provided for enhancing continuity in service of a radio authorized to transmit in shared spectrum by setting a transmit expiry time based upon whether the radio must cease transmission when a dynamic incumbent user operates in the dynamic protection area (DPA) to avoid aggregate interference to a receiver of the dynamic incumbent user, in or about the DPA, exceeding a threshold interference level.
