Abstract: Methods are provided for managing frequency channels in a shared spectrum available to a radio local access network (RLAN) access point (AP) in a wireless network. The methods may comprise receiving a request for channel availability from the RLAN AP to access the shared spectrum, computing, based on a plurality of parameters associated with the RLAN AP, an RLAN service area (RSA) associated with the RLAN AP, retrieving one or more incumbent protection contours (IPCs) associated with one or more incumbent users in the wireless network, identifying an IPC, among the one or more retrieved IPCs, that overlaps with the RSA associated with the RLAN AP, determining, based on the identified IPC, available frequency information corresponding to the received request for channel availability, and transmitting, to the RLAN AP, a channel availability response comprising the available frequency information.

Abstract: Improved techniques are provided for managing and optimizing network resources and spectrum access in a Self-Organizing Network (SON). A Spectrum Access System (SAS) collects network-related information from a plurality of network sources, such as base stations and user equipments (UEs), to perform optimization and organization across different networks, network operators, and network technologies. In some embodiments, the SAS may use the network information and a Radio Environment Map to optimize TDD synchronization in the SON. In other embodiments, the SAS may use the network information to populate a global Neighbor Relation Table. The SAS also may use the network information to optimize one or more network parameters, such as Physical Cell Identities or Root Sequence Indexes, antenna parameters, transmit power levels, handover thresholds, channel assignments, and so on, for use in the SON. Advantageously, the SAS's optimized network parameters may be used to improve network performance, reduce signal interference, and adjust to network failures in the SON.

Abstract: Cloud-based systems and methods are provided for assigning shared spectrum resources to secondary users. The methods may comprise receiving, by a central block entity, a request for channel availability from a secondary user to access a shared spectrum in a wireless network, authenticating the secondary user, validating the secondary user, routing the request for channel availability to a managing block entity, receiving available frequency information from the managing block entity, assigning a frequency and an effective isotropic radiated power (EIRP) to the secondary user based on the available frequency information from the managing block entity, and transmitting, to the secondary user, a channel availability response based on the assigned EIRP. The managing block entity may be configured to determine available frequency information based on one or more parameters associated with the secondary user. The channel availability response may comprise a frequency on which the secondary user can transmit.

Abstract: Improved techniques are provided for managing frequency channels in a shared spectrum available to a radio local access network device (RLAN) in a wireless network. A shared spectrum system may perform operations including retrieving a plurality of parameters for one or more high-priority users in the wireless network; computing, based on the retrieved parameters, a plurality of interference-to-noise power ratio (I/N) contour values; storing the plurality of I/N contour values in a database; receiving, from the RLAN in the wireless network, a request for channel availability, wherein the received request includes at least a first value; extracting, based on the first value in the request for channel availability, I/N contour values from the database exceeding a threshold value; determining, based on the extracted I/N contour values, available frequency information corresponding to the received request for channel availability; and transmitting a channel availability response comprising the available frequency information.

Abstract: The disclosed embodiments provide improved methods and systems for predicting spectrum allocation in a wireless access network. The method may comprise receiving data associated with an access point (AP), creating, based on the received data and a machine learning algorithm, a decision model for predicting whether to allocate spectrum to the AP, generating a prediction, using the decision model, whether to allocate spectrum to the AP, and sending the prediction to a spectrum access system (SAS) in the wireless access network. The SAS may be configured to allocate spectrum to the AP based on the prediction.

Abstract: A method and system is provided for enabling spectrum sensing capability in a network having at least one primary user and a plurality of secondary users configured to communicate using a shared spectrum. The methods and systems include receiving values from sensors corresponding to received signal strength from a primary user in one or more frequencies of the shared spectrum. The values are used to interpolate at least one additional value between the sensors. A detection threshold is determined for sensing a signal transmitted from the primary user based on an acceptable amount of interference. The primary user is then determined to be transmitting in the one or more frequencies of the shared spectrum if any of the values received from the plurality of sensors or the at least one additional value interpolated along the path exceeds the detection threshold.
