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.

Abstract: An interface circuit in an electronic device may provide rate feedback. During operation the interface circuit may transmit one or more packets or frames associated with a data stream that are intended for the recipient electronic device, where the data stream is associated with a video encoder. Then, the interface circuit may estimate a communication performance metric associated with at least the transmissions. For example, the estimated communication performance metric comprises an effective capacity associated with a wireless link between the electronic device and the recipient electronic device. Moreover, the effective capacity may be estimated based at least in part on an efficiency of the wireless link. Next, the interface circuit may provide the rate feedback intended for the video encoder based at least in part on the estimated communication performance metric. In some embodiments, when beamforming occurs, the rate feedback may be reset.

IPC: H04W76/27
Abstract: While in an inactive state, a user equipment (UE) device transmits a message to a base station. The message indicates the UE device's intent to perform transmission and/or reception of user data with the network during the inactive state. The message may include a portion of the user data and/or a buffer status report. The UE device receives a response message that induces a state transition in the UE device. Different state transitions (e.g., to idle, inactive, legacy inactive, connected) may be induced by different types of response message (e.g., release, release with suspend configuration, resume, setup). One particular type of response message causes the UE to stay in the inactive state and enables subsequent user data transmission/reception in the inactive state. The response message may implicitly (or explicitly) indicate that forwarding of the user data to a core network was successful.

Abstract: An interface circuit in an electronic device may perform wireless link adaptation. During operation the interface circuit may transmit at least two data streams, where a first data stream of at least the two data streams has a higher quality-of-service (QoS) criterion and a lower modulation coding scheme (MCS), and a second data stream of at least the two data streams has a lower QoS criterion and a higher MCS. Then, the interface circuit may estimate a communication performance metric associated with the second data stream. Next, the interface circuit may selectively transmit an MCS probe associated with the second data stream based at least in part on the communication performance metric and the lower QoS criterion. Moreover, in response to receiving feedback information associated with the recipient electronic device and the MCS probe, the interface circuit may modify the first MCS and/or the second MCS.
