Abstract: Aspects herein provide a system, media, and methods for a mobile edge computer that renders extended reality (XR) in support of a local user device, via a local network. The mobile edge computer can continue to provide updated XR renderings in near real-time when user position data remains within a particular viewing angle, without requesting updated content or rendering assistance from a remote application. When user position data is determined to be outside of the viewing angle, then the mobile edge computer may request additional content from the remote application.

Abstract: Recovering bearers after a service interruption of a relay node includes receiving, at a relay gateway, an instruction to modify bearers from a mobility management entity (MME), the instruction identifying one or more bearers that were in use by the relay node prior to the service interruption, identifying, at the relay gateway, at least one additional bearer in use prior to the service interruption not identified in the instruction received from the MME, and instructing the MME to create the at least one additional bearer. The at least one additional bearer can include a non-GBR bearer, such as a bearer with QCI of 1 used for VoLTE.

Abstract: Aspects herein provides a system that utilizes a virtualization layer at a distribution unit or central unit in a network. The virtualization layer includes a plurality of virtual resource blocks that are pooled together as a resource for both a public portion of the network and one or more private portions of the network. Based on loading monitoring of the different portions of the network, the plurality of virtual resource blocks in the pool can be dynamically reallocated between the public and private networks to accommodate and optimize loading. The plurality of virtual resource blocks are mapped to physical resource blocks for scheduling and utilization based on the reallocation.

Abstract: Systems and methods are provided for controlling implementation of network policies in a system including a core network and an open radio access network (O-RAN). The method includes receiving a request for accessing one of multiple network components from an application at a centralized network policy controller. The method additionally includes evaluating the request at the central network policy controller to determine if the request is core related or RAN related and assigning the application to a selected one of the multiple network components based on the evaluation, wherein the selected one is a core component when the request is core-related and the selected one is a RAN component when the request is RAN-related.
