Abstract: A base station establishes a wireless connection in a first portion of a frequency band with a user equipment located in a first geographic area. The first portion is allocated to an operator of the base station in response to a request transmitted to a spectrum access server (SAS). The user equipment is handed over from the first portion to a second portion of the frequency band in response to detecting presence of an incumbent that is allocated a third portion of the frequency band for exclusive use within a second geographic area that overlaps with the first geographic area. The third portion overlaps with the first portion. The second portion is allocated to the operator in response to the request. The first portion and the second portion are separated by a frequency bandwidth that is larger than a threshold determined based on a frequency bandwidth allocated to incumbents.

Abstract: An edge cloud network includes one or more base stations that support wireless communication with a plurality of sensors. The edge cloud network also includes a core network that stores data collected using the plurality of sensors. The edge cloud network further includes a machine learning (ML) analytics server configured to analyze the data collected using the plurality of sensors. The edge cloud network implements sensor data provenance to ensure integrity and localization of the data within the edge cloud network. The base station supports wireless communication in at least one of a licensed spectrum, a shared Citizens Broadband Radio Service (CBRS) spectrum, an unlicensed spectrum, and an opportunistically available licensed spectrum.

Abstract: A radio access network element includes a memory and at least one processor coupled to the memory. The memory stores computer-readable instructions. The at least one the at least one processor configured to execute the computer-readable instructions to: estimate, for a multimedia flow for a user equipment, a throughput for each of a plurality of different air interfaces, the throughput for a respective air interface among the plurality of different air interfaces including (i) an amount of available bandwidth on the respective air interface and (ii) an amount of available bandwidth on a backhaul link associated with the respective air interface; select an air interface from among the plurality of different air interfaces based on the throughput for each of the plurality of different air interfaces; and admit the multimedia flow on the selected air interface.

Abstract: An apparatus such as a domain proxy implemented in an edge cloud of a private enterprise network includes a processor configured to aggregate traffic for Citizens Broadband radio Service Devices (CBSDs) in a private enterprise network. The apparatus also includes a transceiver configured to monitor communication with geo-redundant instances of a spectrum access system (SAS) that allocate frequency bands in a shared spectrum to the CBSDs. The processor is configured to instantiate a local SAS in response to the geo-redundant instances of the SAS becoming unavailable. The local SAS is configured to respond to heartbeat messages from the CBSDs. The local SAS is also configured to attempt to establish a connection with an environmental sensing capability (ESC) in response to the geo-redundant SASs becoming unavailable.

Abstract: A spectrum access system (SAS) grants one or more channels of a shared spectrum to a base station, e.g., in response to receiving a registration request from the base station. The SAS increments a usage of a connection between the base station and the SAS in response to the SAS receiving information indicating that the base station has an active connection with the apparatus during a service time interval. The processor does not increment the usage if the base station does not have an active connection with the apparatus during the service time interval. In some cases, the active connection is indicated by heartbeat messages exchanged between the base station and the SAS. A customer associated with the base station is charged a cost based on the usage determined by the SAS.
