Abstract: Systems, methods, and machine-readable media for obtaining data from a cellular network core are described herein. A request from a network function residing outside of the cellular network core may be received by the cellular network core. The request may correspond to a request for data from the cellular network core. The request may be routed by a network exposure function (NEF) of the cellular network core to a user plane function (UPF) of the cellular network core. UPF data responsive to the request may be determined by the UPF. The UPF data may be transmitted from the UPF to the network function residing outside of the cellular network core

Abstract: Various arrangements for using different air interfaces on adjacent frequency channels for side-link communications are presented. A first side-link channel may be split into a first bandwidth portion and the second bandwidth portion, in which the first bandwidth portion of the first side-link channel is directly adjacent to the second side-link channel. A first subcarrier spacing may be assigned to the first bandwidth portion of the first side-link channel. The second side-link channel may also use the first subcarrier spacing. A second subcarrier spacing may be assigned to the second bandwidth portion of the first side-link channel that differs from the first subcarrier spacing.

Abstract: Various systems and methods for cellular network slice management are presented. An application may be determined to be authorized to manage a cellular network slice utilized by the application for communication with user equipment. A request can be received from the application to modify the cellular network slice from the application. In response to the request, a parameter of the cellular network slice may be modified. The cellular network can then use the modified slice for communication with user equipment for the cloud-based application.

Abstract: Embodiments are directed towards systems and methods for managing user experiences during cellular telecommunication outages within a wireless telecommunication network, such as a wireless 5G network. Example embodiments include systems and methods for utilizing an intelligence layer module external to the DU and in communication with the DU, a primary physical data center and a backup physical data center for managing user experiences during a cellular telecommunication network outage. The intelligence layer module external to the distributed unit (DU) communicates with the DU to activate and manage the radio resource manager (RRM) in the DU to reduce interruptions in service during the cellular telecommunication network outages.

Abstract: Systems, methods, and devices dynamically allocate bandwidth parts in response to conditions at cell sites. An example process assigns a first plurality of slices and a second plurality of slices to communicate on a bandwidth of a cell site. The cell site operates at a first level of power consumption. A changed operating state is detected at the cell site, and the first plurality of slices is assigned to communicate on a bandwidth part of the cell site in response to detecting the changed operating state. The bandwidth part is a subset of the bandwidth. The cell site operates at a second level of power consumption in response to assigning the plurality of slices to communicate on the bandwidth part. The second level of power consumption is less than the first level of power consumption.

Abstract: Spectrum and radio resources associated with a 5G radio unit (RU) of a host network are dynamically allocated amongst one or more guest networks. A provisioning plane receives inputs from a guest network operator that identifies desired times, locations and/or frequency bands for desired network coverage. The provisioning plane responsively identifies bandwidth allocations that meet the requested parameters for exclusive use by the guest network. User equipment (UE) associated with each guest network maintains time and frequency synchronization with the host network, but otherwise limits its communications to the frequency bands allocated to the guest network. By dynamically obtaining physical radio and spectrum resources from a host provider and by scaling backend network capabilities using cloud resources, guest networks for any number of different purposes can be quickly deployed or modified as desired.
