Abstract: Methods, systems, and devices for wireless communication are described. In one method, a source access node (AN) of a local area network (LAN) may receive, over a first connection, a set of fast transition (FT) parameters pertaining to authentication. The source AN may cache the set of FT parameters, and forward the set of FT parameters to a target AN of the LAN during a handover procedure. The source AN may receive, from the target AN, a set of security parameters associated with secure communication between the wireless device and the target AN, the set of security parameters based at least in part on the set of FT parameters. The source AN may subsequently transmit to the wireless device, over the first connection, a command to perform a handover to the target AN, the command including the set of security parameters.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may establish a packet data network (PDN)-connectivity session to a PDN using a cellular radio access technology (RAT) and migrate the PDN-connectivity session from a source access node (AN) to a target AN. Migration may initiate when a decision to perform a handover is made. The target AN may receive a network address and information about a first data radio link established between the UE and source AN. The target AN may establish a second data radio link with the UE based at least in part on the first data radio link information, and may transmit, to the PDN, a path update including the network address and an updated path via the target AN. In some cases, the target AN may forward packets between the UE and the PDN via the second data radio link.

Abstract: Methods, systems, and devices for identification reinterpretation in sidelink control information (SCI) are described. A first user equipment (UE) may transmit to a second UE or device, on a sidelink channel, SCI. The SCI may include a partial source and destination identifier fields and may indicate to the second UE to apply a first interpretation of multiple different interpretations for the partial source identifier field and the partial destination identifier field. For example, the SCI may indicate to interpret the partial source identifier field and the partial destination identifier field in combination as a source identifier field, as a destination identifier field, or as a partial source identifier and a partial destination identifier. The UE may transmit a medium access control (MAC) packet including a MAC header with identifier fields set to be complementary to the SCI.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a network may establish a multiple access (MA) packet data unit (PDU) session for a local area data network (LADN) and may reconfigure a registration area to map to a LADN service area. A network may establish an MA PDU session for an LADN, but may steer traffic to only one of two access links. A network may reject a request for an MA PDU if it is for an LADN. A user equipment (UE) may be configured to trigger a UE registration update or other location information if it leaves an LADN service area while in an idle mode with one access network and a connected mode with the other access network. A UE may request LADN registration, and the network may provide the UE with an indication that MA PDU sessions for the LADN are not supported.

Abstract: Apparatus, methods, and computer-readable media for facilitating a cloud-based vehicle XR user experience are disclosed herein. An example method for wireless communication at a user equipment (UE) includes transmitting a request for a vehicle extended reality (XR) session. The vehicle XR session may be based on a first user XR stream including a vehicle XR component associated with a vehicle and a first user XR component associated with a first user. The first user may have an association with the vehicle. The example method also includes transmitting uplink information associated with the first user XR stream. The example method also includes receiving rendering information associated with the first user XR stream. The rendering information may be based on the uplink information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive configuration information identifying the UE as a relay node and indicating for the UE to schedule resources for other UEs. The UE may receive a single message from a network entity with the configuration information or multiple messages from the network entity with the configuration information. A remote UE may request scheduling information from the relay UE. A network entity, such as a base station, may provide one or more resources (e.g., time resources, frequency resources, or both) for the relay UE to schedule one or more remote UEs. The relay UE may send scheduling information to the one or more remote UEs based on receiving the resources.

Abstract: Aspects of the present disclosure describe indicating per-packet quality of service (QoS) in communications by a wireless communications device. A packet from an application generated for a first radio access technology (RAT) can be obtained, where the packet includes a first QoS value associated with the first RAT, and/or the first QoS value can be mapped to a second QoS value associated with the second RAT. In another example, the QoS value can be indicated in the packet along with a reflective indicator indicating to use the QoS value in transmitting a response to the packet.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) of a group of UEs may communicate with other members of the group to provide data or other information via sidelinks. The UE may transmit a groupcast sidelink request to the base station. After receiving the sidelink request, the base station may send a sidelink grant (e.g., transmit or receive grant) in downlink control information (DCI) to the UEs in the sidelink groupcast communications group. The sidelink grant may include information for each hop such as which UEs are going to transmit or receive, the reception or transmission beams of the UEs, time and frequency resources, or the data to forward or relay. In some examples, a UE may relay information to other UEs in the sidelink groupcast communications group.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a first user equipment (UE) and a second UE. The first UE may receive, from a base station, a sidelink resource configuration indicating physical sidelink control channel (PSCCH)/physical sidelink shared channel (PSSCH) occasions on which to monitor a PSCCH for a grant from a second UE. The first UE may determine an active time for monitoring the PSCCH based on a discontinuous reception (DRX) mode for a link with the base station, the DRX mode including an active state in which a physical downlink control channel (PDCCH) is monitored and an inactive state in which the PDCCH is not monitored. The first UE may monitor the PSCCH during one or more of the PSCCH/PSSCH occasions that coincide with the active time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration. The configuration may indicate component carriers for sidelink carrier aggregation and parameters associated with cross-carrier feedback. The UE may receive a first transmission block on a first component carrier and a second transmission block on a second component carrier. The UE may transmit a physical sidelink feedback channel (PSFCH) on a third component carrier with the cross-carrier feedback. The cross-carrier feedback may include a set of acknowledgement/negative acknowledgement (ACK/NACK) bits and an indication of an association between each ACK/NACK bit and a corresponding one of the first component carrier, the second component carrier, the first transmission block, or the second transmission block. Numerous other aspects are described.
