Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

Abstract: This disclosure relates to providing early packet delivery to radio link control. A transport block may be received by a wireless device via wireless communication. The transport block may fail a transport block cyclic redundancy check, but a subset of the code blocks of the transport block may pass code block cyclic redundancy checks. Packet data from the subset of the code blocks that pass code block cyclic redundancy checks may be provided to a radio link control layer of the wireless device, based at least in part on the successful code block cyclic redundancy checks for those code blocks.

Abstract: A service device (e.g., a user equipment (UE), or other network component) can operate generate sidelink communications with peer UE devices based on PC5 unicast link to enable a direct peer-to-peer communication as part of PC5 vehicle-to-everything (V2X) communications. Radio status link detection can be configured based on a keep alive (KA) coordination scheme via the PC5 unicast link to monitor a status of the PC5 unicast link. A KA timer can be configured based on the KA coordination scheme via the PC5 unicast link. The KA coordination scheme is configured to reduce redundant KA requests in the PC5 unicast link to coordinate the direct peer-to-peer communication across the PC5 unicast link.

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: Apparatuses, systems, and methods for performing network slice quota management. A network slice quota management function may store capacity information for one or more network slices. The network slice quota management function may receive a request for an indication of whether a network slice has additional capacity. The network slice quota management function may provide an indication of whether the network slice has additional capacity in response to the request. The capacity information may relate to the capacity of the network slice with respect to the number of wireless devices registered for the network slice, or to the capacity of the network slice with respect to the number of packet sessions established with the network slice, or both, among various possibilities.
