Abstract: Techniques for automating delivery of data of a radio to a spectrum access system are provided. The data is used by the spectrum access system to use the data to control transmission of the radio to regulate interference in shared spectrum at an incumbent or primary user, where the radio is that of a secondary user.

Abstract: A method for detecting interference in a wireless system is disclosed. The method includes receiving an uplink signal at a remote radio head in a distributed base station, passing the uplink signal from the remote radio head to a baseband unit over a front-haul communication link as baseband IQ data, and intercepting the baseband IQ data at a tester coupled between the remote radio head and the baseband unit. Processing of the IQ data is performed to determine whether an interfering signal is present in the uplink signal.

Abstract: A system is provided. The system comprises a radio frequency (RF) planning system, comprising: a first processing system; a first communications system coupled to the first processing system; at least one input/output device coupled to the first processing system; wherein the first processing system comprises first memory circuitry and first processor circuitry; and wherein the first processing system is configured to: receive proposed RF access system design criteria; synthesize an RF access system design; assess interference using shared spectrum system data and data about the synthesized RF access system design; determine if the proposed RF access system design criteria are acceptable based upon the interference assessment; and if the proposed RF access system design criteria are unacceptable, then adjust the proposed RF access system design criteria.

Abstract: The present disclosure describes systems and methods for determining intermodulation distortion in a system such as, but not limited to, a communication system. In an embodiment, intermodulation distortion is determined by injecting a signal into a frequency band which interacts with a second signal, searching a second frequency band for a product signal formed from the first and second signals, applying a cyclostationarity detection technique to the product signal and identifying the product signal as an intermodulation distortion signal.

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 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 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.
