Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for receiving, by a relay user equipment (UE) from a remote UE, a remote UE radio resource control (RRC) message for establishing a relayed communication between the remote UE and a network entity via the relay UE; determining, by the relay UE, remote UE information associated with the remote UE for establishing a remote UE communication context between the relay UE and the network entity based on the remote UE RRC message; and transmitting, by the relay UE to the network entity, the remote UE RRC message and the remote UE information.

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: Aspects of the disclosure relate to mechanisms for proximity service (ProSe) authorization and provisioning. A user equipment (UE) may be configured to support ProSe communication and may indicate this capability to a radio access network (RAN) and a core network during registration of the UE. Based on the ProSe indication, the RAN may select an access and mobility management function (AMF) that supports ProSe authorization and policy provisioning and forward a registration request indicating the UE supports ProSe communication to the selected AMF. Upon authorizing the UE for ProSe operation, the AMF may transmit a registration accept message including a ProSe supported indication to the UE. The UE may then initiate a ProSe session with another UE based on the ProSe supported indication in the registration accept message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may provide a session request associated with establishing a proximity services (ProSe) session. The session request may include ProSe session specific information including information that indicates a ProSe service type associated with the ProSe session. The user equipment may receive a session establishment response after providing the session request. The session establishment response may include at least one of a ProSe session authorization indication associated with the UE, or ProSe policy information for the ProSe service type associated with the ProSe session. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to performing a handover on a per-data radio bearer (DRB) basis. In some examples, the disclosure is directed to indicating, to a source network entity, a make-before-break (MBB) handover capability of the UE, the MBB handover capability supporting MBB handovers for one or more DRBs identified by the source network entity. In some examples, the disclosure describes receiving, from the source network entity, configuration information for a handover from the source network entity to a target network entity, the configuration information identifying the one or more DRBs supported for the MBB handover.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a prioritization rule that indicates a relative priority for different uplink communications included in a group of uplink communications, wherein the group of uplink communications includes at least a first uplink communication and a second uplink communication to be transmitted by the UE using time-division multiplexing during a make-before-break handover procedure. The UE may transmit, based at least in part on the prioritization rule, the first uplink communication to a target base station and the second uplink communication to a source base station using time-division multiplexing during the make-before-break handover procedure. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a master node (MN) may receive an acknowledgment message from a secondary node (SN). The MN and the SN may provide dual connectivity with a core network for a user equipment. The MN may provide an address indication message to the SN. The address indication message may include MN downlink transport network layer (TNL) information for an SN terminated data radio bearer (DRB) that requires master cell group (MCG) resources. The address indication message may be provided in a first message that immediately follows the acknowledgment message. In some aspects, the SN may receive the address indication message, and may forward, based at least in part on the MN downlink TNL information, downlink data for the SN terminated DRB that requires MCG resources. 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 detect that a timer has expired prior to completing a handover of the UE from a source base station (BS) to a target BS. In some aspects, the UE may selectively declare, based at least in part on detecting that the timer has expired, a radio link failure. Numerous other aspects are provided.

Abstract: Methods for performing a handover in wireless communications for a user plane function (UPF) are disclosed. In an aspect, the method includes establishing a tunnel between the UPF and a target base station based on information in a path switch preparation request for a make before break handover of a user equipment (UE) from a source base station to the target base station, the path switch preparation request being received in response to a request originating by the target base station. The method further includes bi-casting a downlink data packet unit (PDU) to a source base station and to the target base station with a same sequence number (SN) in a tunnel protocol, receiving PDUs from the source base station and the target base station with corresponding PDUs having the same SNs in the tunnel protocol and discarding received duplicate PDUs based on the SNs in the tunnel protocol.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.
