Abstract: Various arrangements for improving cell coverage are presented. A cellular network can define a first bandwidth part and a second bandwidth part to be implemented concurrently by a base station of the cellular network. The first bandwidth part and the second bandwidth part do not overlap and may be separated by a guard band. The first bandwidth part can have a greater bandwidth and greater sub-carrier spacing than the second bandwidth part. The cellular network can determine a first set of user equipment to use the first bandwidth part for communication with the base station and a second set of user equipment to use the second bandwidth part for communication with the base station. Communication with the first set of user equipment using the first bandwidth part and the second set of user equipment using the second bandwidth part may be performed.

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: A new radio base station establishes a first and a second component. The first and second component carrier overlap each other. The base station transmits first synchronization signal blocks on the first component carrier. The base station transmits second synchronization signal blocks on the second component carrier interleaved in time with the first synchronization signal blocks.

Abstract: An apparatus comprises a memory and a processor communicatively coupled to one another. The memory may be configured to store one or more directories comprising access to multiple tenant profiles and one or more network access commands configured to provide access to one or more entitlements. Each tenant profile of the tenant profiles are associated with one or more services. The processor may be configured to receive a request to access at least one service. The request comprises an application function identifier (AFID) comprising a tenant ID that references a tenant profile of the tenant profiles, a department ID that references multiple entitlements associated with the tenant profile, and an API ID that references a service associated with the entitlements. Further, the processor may be configured to generate a report comprising multiple network access commands configured to enable access to the service in accordance with the entitlements.

Abstract: Embodiments are directed towards systems and methods for hierarchical network slicing for communication services. An example method includes obtaining a set of single network slice selection assistance information (S-NSSAI); for each S-NSSAI of the set, determining a Tenant Slice-Group based, at least in part, on a slice differentiator (SD) part of the S-NSSAI; and processing the set of S-NSSAI in accordance with a hierarchy of network slicing including a plurality of Tenant Slice-Groups each including one or more network slices. The slices can inherit functionality from their respective root of a corresponding Tenant Slice-Group, geographic granularity or availability of each slice can be based on its Tenant Slice-Group, and Unified Access Control (UAC) can be implemented based, at least in part, on Tenant Slice-Group identification.

Abstract: Systems and method dynamically determine provisioning of networking services. A service area is serviced by a first user plane function (UPF) as a primary service area and by a second UPF as a secondary service area. A request is received from a user equipment to connect to a network, and a location of the user equipment is identified. Determination is made whether the location is in the first service area. A first load of the first UPF is determined. In response to the first load not exceeding a load threshold value, the user equipment is connected to the first UPF. In response to the first load exceeding the load threshold value, the user equipment is connected to the second UPF when a second load thereof does not exceed the first load or to the first UPF when the second load exceeds the first load.

Abstract: Various arrangements for spectrum sharing among a terrestrial network and a non-terrestrial network are presented herein. A first bandwidth part having a first frequency range for may be assigned use for communication between one or more UE of a plurality of UE and a terrestrial cellular network when a high signal strength is present. A second bandwidth part having a second frequency range may be assigned for use for communication between one or more UE of the plurality of UE and the terrestrial cellular network when a low signal strength is present. A third bandwidth part having a third frequency range can be assigned for use for communication between one or more UE of the plurality of UE and a non-terrestrial network. The third bandwidth part can overlap with the first bandwidth part but not the second bandwidth part.

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.
