Abstract: An application specific interface (AA-NAPI) associated with an application for the purpose of controlling the networking aspects of the application session is provided by communication service provider (CSP). Cost model of network service types associated with a specific application type is learned by using the AA-NAPI. For each service-point joining the session, network properties are queried by using the AA-NAPI. During continuous service quality monitoring, upon detection of quality degradation leading to the decision to upgrade session quality, network service-type associated with a specific server-point is changed by using the AA-NAPI. Network specific actions are taken to reconfigure the network so that the requested service type is received by the specific service-point. New network capability is activated to improve network service level by using the AA-NAPI. Network specific actions are taken by the network to install new network capabilities so that the specific service-point's service quality is improved as requested.

Abstract: An apparatus includes an optical device to output a data-modulated optical signal, an electrical radio-frequency (RF) driver to drive the optical device with one or more RF drive signals, a photodetector to provide a measure of a light intensity output by the optical device, and an electronic controller. The electronic controller is configured to dither an amplitude of at least one of the one or more RF drive signals at a dithering frequency. The electronic controller is also configured to adjust one or more operation settings of at least one of the electrical RF driver and the optical device based on a component of the measure of a light intensity at the dithering frequency.

Abstract: Disclosed are methods for controlling downlink transmissions in an integrated access and backhaul network. An example method may include determining to control a first downlink transmission for a first interface between a second apparatus associated with a user plane of the central unit of the donor and a node in the integrated access and backhaul network, and transmitting, to the second apparatus, a first non UE-associated signaling request to control the first downlink transmission for the first interface, the first non UE-associated signaling request including information associated with the node. Related apparatuses and computer readable media are also disclosed.

Abstract: Described herein are methods, apparatuses, and computer program products configured to synchronize radio bearers carrying data flows and/or control flows from a network entity or node within a communication system (e.g., a 5G network), towards user equipment, in order to achieve a desired Quality of Experience (QoE) for applications with multiple data streams and multiple quality of service (QoS) flows whose QoS requirements depend on each other. In some embodiments, two or more data radio bearers (DRBs) for carrying data from a single application, such as extended reality, virtual reality, augmented reality, or the like, e.g. online game streaming, may be synchronized in order to ensure desired QoE for an application with multiple QoS flows.
