Abstract: In some aspects, the present disclosure relates to a method for performing packet flow description (PFD) management, the method including establishing a Quality-of-Service (QoS) flow between a user equipment (UE) and a core network (CN) for a data flow of an application, creating, by the UE, a UE-requested packet flow description (PFD) upon a change in the data flow, sending, from the UE to the CN, a request to the CN for updating a CN PFD to an updated PFD using the UE-requested PFD, receiving, at the UE from the CN, a downlink (DL) packet mapped to the QoS flow using the updated PFD.

Abstract: Systems, methods, and devices are described to facilitate soft signaling between a user equipment (UE) and a network element. A UE and a network element can exchange HTTP or Websocket messages to identify and request network resources needed for the UE to access and use application services. The network element can use requested network resources to cause the configuration of a connection between the UE and a radio access network.

Abstract: Apparatuses, systems, and methods for Reflective Quality of Service (RQoS) enhancements. Methods may include enhancements for both UE behavior and network function behavior. Network function behaviors may include enhancements to UPF behavior and SPF behavior. Enhancements to RQoS may include methods for resetting an RQoS indicator (RQI) bit for downlink packets of a flow destined for a UE, methods for generating a flow ID to include in a SDAP header destined for a UE, methods for using the flow ID to limit L3 and L4 header parsing, methods for sending/receiving feedback regarding processing of the RQI bit, methods for maintaining a QFI mapping table, methods for skipping parsing of SDAP header fields, methods for specifying and signaling a QoS Flow Identifier (QFI) range to a UE, methods for limiting downlink header parsing, methods for updating a QFI, and methods for performing high efficiency RQoS processing.
