Abstract: Certain aspects of the present disclosure provide techniques for communicating, by a user equipment (UE), over multiple slices. A method that may be performed by the UE includes receiving, by a modem, from an operating system (OS), a request for route identifier, the request for route identifier comprising a traffic descriptor corresponding to a first application from which the request for route identifier originated. The method further includes transmitting a route identifier to the OS, the route identifier generated by the modem based on a routing policy that provides mapping between the traffic descriptor and a network route. The method further includes receiving, by the modem, a start network request comprising the route identifier. The method further includes establishing, in response to the start network request, a network connection via the network route.

Abstract: Aspects of the disclosure relate to mechanisms for enhancement in UE cell selection to prioritize cells supporting 5G New Radio (NR) in standalone mode (SA) and in non-standalone (NSA) mode. In some examples, a UE may identify a plurality of cells within an area including a location of the UE. Each cell supports at least one radio access technology (RAT) and at least one frequency. The UE may determine a selection order of the plurality of cells based on the supported RATs and frequency bands to prioritize cells supporting the latest RAT (e.g., 5G NR) and select a serving cell based on the selection order.

Abstract: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving voice over new radio (VoNR)-to-voice over long term evolution (VoLTE). An example method generally includes communicating with and camping on a next generation node B (gNB) in a 5G new radio (NR) system; initiating a voice call with the gNB; receiving a 5G NR-to-long term evolution (LTE) handover command in response to initiating the voice call; performing a handover procedure in response to the handover command; detecting a failure in the handover procedure; and taking one or more actions in response to detecting the failure in the handover procedure.

Abstract: Certain aspects of the present disclosure provide techniques for accessing home operator services with the home subscription using radio access from a subscription on a separate operator. A method that may be performed by a user equipment (UE) includes obtaining a data connection with a first wireless network based on a first subscription, obtaining a tunnel connection with a gateway of a second wireless network through the data connection based on a second subscription associated with the second wireless network, and communicating with the second wireless network through the tunnel connection using the data connection.

Abstract: Various embodiments provide methods, vehicle computing devices, storage media, and systems for unicast transmission of cellular vehicle-to-everything (C-V2X) Internet Protocol (IP) packets. Various embodiments may enable upper layers in a stack architecture to realize unicast transmission of C-V2X IP packets. In various embodiments, source port and destination IP address pairings may be associated with destination layer 2 (L2) addresses. In various embodiments, a source port indication and destination IP address indication may be added to a unicast C-V2X IP packet, such as a transmission control protocol (TCP) packet, a user datagram protocol (UDP) packet, etc., and the source port and destination IP address indications may be used by a modem to determine the destination L2 address for the unicast C-V2X IP packet.

Abstract: Various embodiments include methods for autonomous beam switching by a wireless device. A processor of the wireless device may measure signal parameters of signals received from a first synchronization signal block (SSB) beam of a base station monitored by the wireless device and other SSB beams of the base station, determine whether a difference in measured signal parameters of signals received from the first SSB beam and another SSB beam of the base station satisfies a signal quality difference threshold, and autonomously switching to the second SSB beam as the serving beam in response to determining that the difference in the measured signal parameters of signals received from the first SSB beam and a second SSB beam satisfies the signal quality difference threshold. The signal quality difference threshold may be listed in a table in memory or determined via machine learning.

Abstract: A user equipment (UE) modem stores a route selection policy (URSP), the URSP associating each of a plurality of data network name (DNN) identifiers and a corresponding slice, wherein a first DNN identifier (ID) is associated with a first DNN and a first slice and a second DNN ID is associated with the first DNN and a second slice different than the first slice. The modem establishes a first protocol data unit (PDU) session with the first DNN and the first slice in response to receiving a first indication to start a first network interface associated with the first DNN ID. The modem establishes a second PDU session with the first DNN and the second slice in response to receiving a second indication to start a second network interface associated with the second DNN ID.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a master node (MN) may receive information indicating one or more candidate target secondary nodes (SNs) for a multi radio access technology dual connectivity (MR-DC) handover of a user equipment (UE), wherein the information indicates that the one or more candidate target SNs are associated with direct forwarding paths with a source radio access network (RAN) node of the UE; select a target SN from the one or more candidate target SNs based at least in part on the received information; and perform the MR-DC handover of the UE, wherein the selected target SN is different than the source RAN node of the UE, and wherein a configuration of the MR-DC handover is based at least in part on a direct forwarding path between the selected target SN and the source RAN node.
