Abstract: Disclosed is creation of a very narrow bandwidth part (BWP), referred to herein as a virtual BWP. The virtual BWP is created within an operating channel that is not supported by 3rd Generation Partnership Project (3GPP) current standards (e.g., below 5 MHz). This enables a wireless network to be even more flexible in supporting a variety of use cases. In particular, the network artificially creates a small virtual BWP and assigns it to users without requiring any explicit signaling to the user for creating the virtual BWP. The virtual BWPs will limit the physical downlink control channel (PDCCH), the physical downlink shared channel (PDSCH) data region, the physical uplink control channel (PUCCH) and the physical uplink shared channel (PUSCH) for a given user which can be associated with slicing.

Abstract: A disclosed method may include (i) determining, by a RAN intelligent controller (RIC) of a telecommunications network, a RAN function change, (ii) sending the RAN function change to a disaggregated application that is separate from the RIC, the disaggregated application including a small agent of an application of the RIC, and (iii) causing by the small agent of the application of the RIC, the RAN function change to alter a behavior of one or more of a centralized unit (CU) or a distributed unit (DU). Related systems and computer-readable mediums are further disclosed.

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 managing user experiences during a cellular telecommunication network outage involving network communication failure detection and performing different recovery actions in response to detecting a failure in communication between certain telecommunication network components and/or failure of certain network links. For example, the system may perform different recovery actions in response to the failure in communication being due to a detected inactive network link to the central unit control plane (CU-CP) versus the CU-CP itself being initially indicated as inactive

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: 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.
