Abstract: A user equipment (UE) is configured to transmit a first registration request to a network, receive a registration accept message in response to the first registration request comprising a rejected network slice and an indication of a rejection cause corresponding to the rejected network slice and transmit a second registration request to the network comprising a requested network slice, wherein the requested network slice and the rejected network slice are a same network slice.

Abstract: A UE may discard a Plain Authentication Request message or a Plain Identity Request, when received in Service-Request-Initiated state. In such a manner, the UE will not respond to non-integrity protected Authentication Request message or non-integrity protected Identity Request message as part of integrity protected service request procedure (NR and LTE), tracking area update procedure (LTE), or registration request procedure (NR). Thus, a malicious attacker may not use a captured Authentication Request or an Identity Request message to track victim UEs in the network.
A UE may receive a first GUTI from a network. The UE may transition to a Connected mode in response to a paging procedure with the network. The UE may take actions to ensure that a second GUTI is obtained from the network. Other aspects are described.

Abstract: This disclosure relates to techniques for performing wireless communications in context of unified access control. A UE may enter an update needed state. The UE may detect a pending communication. The UE may access the network using an access category associated with the pending communication. The UE may complete the update.

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.
