Abstract: This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer storage media, for uplink switching for enhanced mobility. In some aspects, this disclosure provides techniques for potentially reducing or eliminating service interruptions experienced during a handover from a source cell to a target cell. Additionally, this disclosure provides techniques for potentially simplifying or improving uplink communications while a UE is connected to both the source cell and the target cell during the handover. This disclosure further provides techniques for potentially reducing UE power consumption or improving uplink resource utilization during a handover from a source cell to a target cell while a UE is connected to both the source cell and the target cell during the handover.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine to transmit a pre-allocated uplink (UL) grant to a user equipment (UE), wherein the pre-allocated UL grant includes: a secondary node (SN) transmission configuration indicator (TCI) list, and a type 1 configured grant (CG). The base station may transmit, to the UE, the pre-allocated UL grant based at least in part on determining to transmit the pre-allocated UL grant. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain an indication that a network node is configured to accept a request for the network node to perform network coding for a communication from the UE. The UE may transmit, based at least in part on the UE being within an area associated with the network node, the request for the network node to perform the network coding for the communication. Numerous other aspects are described.

Abstract: A user equipment (UE) establishes a unicast link with a second UE, including establishing an authentication and security establishment procedure between the first UE and the second UE. The UE establishes a security context with the second UE during the authentication and security establishment procedure. The UE starts a timer based on a status of the unicast link. The UE reestablishes the unicast link with the second UE using the security context when the unicast link is reestablished prior to expiration of the timer.

Abstract: A method, apparatus, and computer-readable storage medium for wireless communication at a first user equipment (UE) is provided. The UE receives an indication of one or more timers associated with a radio resource control (RRC) connection establishment procedure or an RRC connection re-establishment procedure with a network entity via a relay. The UE transmits a request associated with an RRC connection to a second UE to be relayed to the network entity and monitors for a response from the network entity based on the one or more timers associated with the RRC connection establishment procedure or the RRC connection re-establishment procedure via the second UE as the relay.

Abstract: Aspects relate to a relay device detecting a change in a protocol data unit (PDU) session configuration that the relay device has established for a user equipment (UE) that accesses a network via the relay device. Upon detecting this change, the relay device signals an indication of the change to the UE. Aspects also relate to UE that is connected to a relay device and that reselects an interworking function (e.g., a non-3rd Generation Partnership Project interworking function (N3IWF)). In some examples, the UE receives an indication from the relay device that a serving relay PDU session configuration has changed and, in response, the UE selects a new interworking function.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) (e.g., a relay UE) may establish a relay connection for routing communications between a network entity (e.g., a base station) and a second UE (e.g., a remote UE). The relay connection may include a sidelink connection and an access link connection. The remote UE may transmit a request to the network entity via the relay UE. The request may include a relay service code associated with the sidelink connection, as well as a request for quality of service (QoS) support for the relay connection. Based on the request, the network entity may determine a QoS configuration for the relay connection. The network entity may indicate the QoS configuration to the UEs via the relay connection. The UEs may adjust parameters of the relay connection to meet the specifications of the QoS configuration.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, handling header compression in scenarios with concurrent connections, such as make-before-break (MBB) handover or dual connectivity (DC) scenarios. A method of wireless communication performed by a user equipment (UE) can include concurrently communicating with a first base station (BS) on a connection with the first BS and with a second BS on a connection with the second BS during a handover procedure. The UE maintains a context for a header compression protocol for the connection with the first BS and the connection with the second BS. The concurrently communicating includes using the header compression protocol context for sending one or more packets, receiving one or more packets, or both.

Abstract: A configuration to enable a UE to monitor the state of the connection with a peer UE in a sidelink communication. The apparatus establishes one or more unicast links with a second UE. The apparatus changes a connection state with the second UE from a sidelink disconnected state to a sidelink connected state based on an establishment of a first of the one or more unicast links. The apparatus changes the connection state with the second UE from the sidelink connected state to the sidelink disconnected state when each of the one or more unicast links with the second UE is released or when a configured timer expires.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a packet data convergence protocol (PDCP) entity of a receiver device receives, from a radio link control (RLC) entity of the receiver device, a plurality of RLC data packets received from a transmitter device over an RLC unacknowledged mode (UM) data radio bearer (DRB) or RLC transparent mode (TM) DRB. The PDCP entity generates a plurality of PDCP data packets corresponding to the plurality of RLC data packets. The receiver device determines to send a PDCP status report indicating a reception status at the receiver device of the plurality of PDCP data packets and transmits the PDCP status report to a PDCP entity of the transmitter device. The receiver device receives, in response to sending the PDCP status report, one or more PDCP data packets of the plurality of PDCP data packets that were not successfully received at the receiver device.
