Abstract: Methods and apparatuses for improving telecommunications services by intelligently deploying radio access network components and redundant links within a data center hierarchy to satisfy latency, power, availability, and quality of service requirements for one or more network slices are described. The radio access network components may include virtualized distributed units (VDUs) and virtualized centralized units (VCUs). To satisfy a latency requirement for a network slice, various components of a radio access network may need to be redeployed closer to user equipment. To satisfy a power requirement for the network slice, various components of the radio access network may need to be redeployed closer to core network components. Over time, the components of the radio access network may be dynamically reassigned to different layers within a data center hierarchy in order to satisfy changing latency requirements and power requirements for the network slice.

Abstract: Embodiments are directed towards systems and methods for carrier aggregation and dual connectivity switching in a cellular network (e.g., a 5G network). Example embodiments include systems and methods for: the RAN functions supporting providing measuring and reporting particular items for dynamic carrier aggregation and dual connectivity switching; RAN dynamic carrier aggregation and dual connectivity switching with a network intelligence layer; RAN dynamic carrier aggregation and dual connectivity switching without a network intelligence layer; RAN dynamic carrier aggregation and dual connectivity switching based on availability of an inter-DU link and meeting latency/bandwidth criteria; RAN dynamic carrier aggregation and dual connectivity switching based on availability of an inter-DU link and meeting resource criteria; and prioritization for using CA instead of DC based on CQI information reported from UEs.

Abstract: Systems and methods to utilize user device self-reported quality metrics and machine learning mechanisms to optimize management of user device mobility in a cellular network. Cells in the network obtain quality data for one or more user devices in communication with the cells, including channel-quality-indicator values, reference-signal-received-power values, and reference-signal-received-quality values. The quality data is processed by a machine learning mechanism to generate a separate quality report for each cell. In response to receiving a request to handover communications for a target user device, the quality reports are utilized to select a cell that is predicted to provide the best quality communications for the target user device.

Abstract: Various arrangements for performing dynamic resource blanking on a cellular network to prevent satellite communication interference are provided. Interference modelling can be provided by a satellite operator that operates a satellite. A cellular network can receive orbital data for the satellite. Based upon the orbital data for the satellite and the interference modelling, the cellular network can blank physical resource blocks (PRBs) for uplink communication with various base stations.

Abstract: Techniques described herein provide pooling of radio access network (RAN) resources in a disaggregated RAN in a manner that enables dynamic re-homing of RAN functions with minimal disruption to stateful communications. The RAN is a hierarchical arrangement of RAN units, each having an associated state at any given time. A RAN state pooling system (RSPS) is in communication with a pool of the RAN units via a high-speed communication channel. The RSPS is configured to maintain an updated repository of the state information for the RAN units in its serviced pool. In the event of re-homing from a first RAN unit to a second RAN unit in the pool (e.g., due to the first RAN unit failing, becoming overloaded, etc.), the RSPS provides the second RAN unit with the updated state information for the first RAN unit to facilitate a stateful re-homing.

Abstract: Example embodiments are directed towards detecting a failure of one or more of a CU-UP pod and a CU-CP pod running on a first cloud compute instance within a node group of a cluster being hosted on a first cloud compute instance. In response to the detection of a failure of one or more of a CU-UP pod or a CU-CP pod of a node group within a cluster being hosted on a first cloud compute instance, the system automatically switches from the one or more pods for which failure was detected to one or more standby pods running a second cloud compute instance with user equipment (UE) context corresponding to the one or more pods for which failure was detected.

Abstract: Systems, methods, and machine-readable media facilitate adaptive beamforming in a cellular network. One or more signals indicative of one or more locations of a first set of one or more radio units and/or a first set of user equipment may be processed. A first set of beamforming specifications may be determined based at least in part on the one or more locations of the first set of one or more radio units and/or the first set of user equipment. The first set of beamforming specifications may correspond to a first set of one or more beamforming patterns. The first set of beamforming specifications may be communicated to instruct the first set of one or more radio units to direct signal transmission in conformance with the first set of one or more beamforming patterns.

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 managing user experiences during a cellular telecommunication network outage involving radio resource manager (RRM) in the distributed unit (DU). The DU detects there exists a failure in communication between the DU and a corresponding central unit control plane (CU-CP) of a 5G NR centralized unit (CU).
