The disclosed technology relates to a process of dynamically assigning operational parameters for access points within a CBRS (Citizen Broadband Radio Service) network. In particular, the disclosed technology monitors for and detects interference between nearby access points and user equipment devices that may belong to the same enterprise or to different enterprises. Machine learning processes are used to revise the operational parameters that were initially assigned by the Spectrum Access System (SAS). These processes are also used to suggest an updated set of operational parameters to the SAS for the access points. The dynamic assignment reduces interference experienced by the access point with respect to nearby other access points and/or nearby other user equipment. The dynamic assignment aims to improve a quality of communication between the access point and its associated user equipment.

Device-to-Device (D2D) communications in hybrid networks are provided by identifying a first dual-mode endpoint seeking to communicate with a second dual-mode endpoint via a D2D communications session; identifying a first communications pattern of network resource usage for the first Radio Access Technology (RAT) and a second communications pattern of network resource usage for the second RAT in the heterogeneous wireless network environment; assigning the D2D communications session to the first RAT based on the first communication pattern and the second communication pattern; and in response to detecting network resource usage changes in the first RAT, transitioning the D2D communications session to the second RAT. In some embodiments, the D2D communications session is assigned to the first RAT using a shared frequency regulated by a band access controller that is reserved as a static resource for D2D communication while high-priority signals are absent from the shared frequency.

Device to device communications in hybrid networks

Systems, methods, and computer-readable media for improving resource management in Citizens Broadband Radio Service (CBRS) networks include a Spectrum Access System (SAS) in coordination with one or more CBRS devices (CBSDs) and a Digital Network Architecture center (DNA-C). Resource allocation decisions can be based on one or more policies such as a priority, a preemption capability index and/or a preemption vulnerability index associated with the CBSDs. Resource allocation can also be based on inter-access point (AP) coordination between two or more CBSDs and comparative performance indicators of the two or more CBSDs. Managing interference between two or more groups of CBSDs can be based on the inter-AP coordination and group identifiers associated with the two or more groups. Bandwidth allocation can be modified to the two or more CBSDs and seamless transition can be implemented using timers.

Managing resources in CBRS networks

Presented herein are methodologies for managing a citizens broadband radio service (CBRS) network. The methodology includes at a spectrum access system (SAS), receiving, from a Donor CBRS base station device (CBSD), a registration request, the registration request including capabilities information about a CBRS Relay Node with which the Donor CBSD communicates, in response to the registration request, sending, from the SAS to the Donor CBSD, a registration response indicating successful registration of the CBRS Relay Node, in response to the registration response, receiving via the Donor CBSD a spectrum enquiry message from the CBRS Relay Node seeking a channel allocation from the SAS, and in response to the spectrum enquiry message, sending from the SAS, and via the Donor CBSD, a resource grant response to the CBRS Relay Node, wherein the resource grant response includes an allocated channel and a maximum EIRP for the allocated channel.

Efficient operation of relay nodes in a citizen broadband radio service (CBRS) network

Presented herein are methodologies for managing a citizens broadband radio service (CBRS) network. The methodology includes receiving, at an enterprise controller, measurement information from a first user equipment (UE) and a second UE, wherein the first UE and the second UE operate in a citizens broadband radio service (CBRS) network; selecting, at the enterprise controller, an information aggregation level based on a predetermined level of privacy associated with the first UE and the second UE; aggregating, at the enterprise controller, the measurement information from the first UE and the second UE in accordance with the information aggregation level to obtain aggregated measurement information; and sending, by the enterprise controller, the aggregated measurement information to a Spectrum Access System that controls allocation of resources in the CBRS network for the first UE and the second UE.

Techniques and mechanisms for a soft migration from an initial or source Spectrum Access System (SAS) of a source SAS provider to a destination SAS of a destination SAS provider for a base station operative to serve as a Citizens Broadband Radio Service Device (CBSD) in a Citizens Broadband Radio Service (CBRS) network are described. While the base station operates to facilitate communications for one or more user equipments (UEs) and is registered with the source SAS for spectrum access, the base station may communicate in one or more message exchanges for registering with the destination SAS and for receiving from the destination SAS a grant for spectrum access to spectrum according to a plurality of operating parameters. After communicating in a message exchange with the destination SAS in a heartbeat procedure for receiving an authorization to use the granted spectrum, the base station may deregister with the source SAS.

Resource Unit (RU) sharing between Access Points in a wireless network is provided by identifying a first Access Point (AP) associated with a first user device, wherein the first AP has won contention for a RU; identifying a second AP associated with a second user device, wherein the first user device and the second user device are located within an overlapping area served by the first AP and the second AP; identifying an unused portion of the RU to which the first AP has not scheduled traffic between the first AP and the first user device; and assigning the unused portion to the second AP for communication between the second AP and the second user device.

Resource unit sharing

A first wireless access point uses a first radio access technology in a heterogeneous wireless network. The heterogeneous wireless network includes the first wireless access point and a second wireless access point using a second radio access technology. The first wireless access point determines one or more performance characteristics of traffic management and traffic between a first client device and the first wireless access point using the first radio access technology and the second wireless access point using the second radio access technology. The first wireless device (access point or some other network device) calculates one or more traffic indicators based on these performance characteristics. The first wireless device further communicates at least one of the one or more traffic indicators to the second wireless access point. The communicated traffic indicators are for use by the second wireless access point to schedule radio resources of the second RAT.

Techniques for routing data in a wireless communication network including a hybrid of infrastructure wireless local area network (WLAN) and neighbor awareness networking (NAN). A subscription is identified between a first NAN device in a first NAN cluster in the network and a second NAN device in a second NAN cluster in the network. The first NAN cluster includes at least one NAN device not included in the second NAN cluster. A first path is generated between the first NAN device and the second NAN device. The first path includes a first network access point (AP) in the network. Data is transmitted from the first NAN device to the second NAN device using the first path comprising the first AP.
