Abstract: Aspects of the present disclosure provide techniques for configuring and triggering conditional handover for UE mobility between a direct connection to the base station (Uu connection) and/or a relay connection (PC5 connection). Specifically, the conditional handover configuration may include preparing multiple candidate relay UEs for handover (e.g., from Uu connection to PC5 connection) and conditional handover execution criteria for relay selection (or reselection) for the UE. Similarly, features of the present disclosure provide techniques for conditional handover transition from a PC5 connection back to Uu connection when conditional handover execution criteria are met (e.g., sidelink signal strength between the two UEs falls below a channel condition threshold). Additionally, the techniques provided herein support for conditional handover of the relay UEs from a first base station to a second station while the relay UE is further supporting one or more remote UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a common key. The UE may communicate with one or more other UEs using a lower layer groupcast key that is based at least in part on the common key, a parameter, and at least one of a group identifier or a destination identifier. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for adaptive paging in sidelink relay scenarios. An example method for adaptive paging by a remote UE generally includes connecting, via a sidelink, to a relay node connected to a network entity, sending an indication of a preferred paging mode to at least one of the relay node or the network entity, and monitoring for paging in accordance with the preferred paging mode, if the UE receives signaling configuring the UE for the preferred paging mode.

Abstract: In one aspect, a remote device generates data for transmission to a network based on an application, selects one of a set of data routing options for routing the data to the network based on policy control information; each of the set of data routing options includes routing the data via a relay device; and transmits the data to the relay device for routing the data via the selected data routing option. In another aspect, a relay establishes a protocol data unit (PDU) session with a network for relaying data received from a remote device based on policy control information, receives data from the remote device, and transmits the data to a base station coupled to the network via the PDU session. Another aspect relates to the base station operation with respect to the above aspects.

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: Certain aspects of the present disclosure provide techniques for switching between a first path and a second path when certain selection criteria are met. The first path may be a Uu connection whereby the remote UE is connected directly to a network entity. The second path may be a connection whereby the remote UE is connected to the network entity (i.e., indirectly) via a relay UE (e.g., by a PC5 connection).

Abstract: Certain aspects of the present disclosure provide techniques for handling a radio link failure timer in the presence of a conditional handover command. A method that may be performed by a user equipment (UE) includes receiving, from a serving cell, a conditional handover command for handing over the UE to a target neighbor cell, wherein the conditional handover command includes one or more triggering conditions for executing a handover to a candidate target cell; monitoring one or more first signals from the candidate target cell for the one or more triggering conditions; and performing one of: stopping a timer based on performing a conditional handover to the target candidate cell; or detecting a timer has expired while monitoring the one or more first signals from the candidate target cell for the one or more triggering conditions.
