Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a remote user equipment (UE) may receive an identifier associated with a relay UE and an identifier associated with a serving cell of the relay UE for a path switch. The UE may receive a local identifier associated with the remote UE based at least in part on connecting with the relay UE over a sidelink interface. The UE may identify, based at least in part on receiving the local identifier, a path switch failure condition associated with the relay UE while the relay UE is in an idle state or an inactive state. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a signal indicating respective execution conditions for a conditional handover (CHO) procedure for each of one or more candidate handover groups, the one or more candidate handover groups comprising a candidate cell group and a candidate relay group, and each candidate handover group associated with a different priority level. The UE may select a handover candidate for performing the CHO procedure based at least in part on determining that the respective execution condition is satisfied for one or more handover candidates of the one or more candidate handover groups and on the respective priority levels of the one or more candidate handover groups. The UE may perform the CHO procedure to the selected handover candidate.

Abstract: Method and apparatus for selection between shared discovery pool and dedicated pool. The apparatus receives, from a UE, a BSR or at least one SR, where the BSR or the at least one SR correspond to at least one of data traffic or discovery signaling. The apparatus configures an uplink grant using shared pool of resources or dedicated pool of resources based at least on the BSR or the at least one SR. The apparatus transmits the uplink grant to the UE.

Abstract: A network entity can trigger a remote user equipment (UE) to switch between an indirect communication link with a network to another indirect communication link or direct communication link with the network. In some aspects, the network entity can trigger the remote UE to perform an inter-gNB switching or sidelink switching using a radio resource control (RRC) connection release procedure or an RRC reconfiguration procedure.

Abstract: Apparatus, methods, and computer program products for disaggregated UE are provided. An example method includes establishing a connection session with the second UE. The example method further includes transmitting a request for establishing a direct radio resource control (RRC) connection with the radio access network via the connection session. The example method further includes configuring a radio bearer of the second UE.

Abstract: A relay user equipment (UE) can relay communication between remote UEs and a network entity via one or more remote device end-to-end (E2E) radio bearers (RB s) established between the network entity and the remote UEs. The remote device E2E radio bearers can be multiplexed into one or more logical channel between the relay UE and the network entity. The relay UE and/or the network entity can allocate communication resources to the remote UEs in consideration of the E2E bearer quality of service (QoS) requirement using, for example, logical channel prioritization at the relay UE and/or different buffer status reports that can provide information on the remote UEs and E2E bearers to facilitate the allocation of resources.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a remote user equipment (UE) may communicate with a base station via a relay UE. For example, the relay UE may operate as a layer 2 (L2) UE-to-network relay supporting a PC5-to-Uu bearer mapping, such that the relay UE forwards messages between the PC5 bearer for the remote UE and the Uu bearer for the base station. If the remote UE determines a trigger event, the remote UE may transmit a measurement report to the base station (e.g., via the relay UE) indicating candidate relays. Based on the measurement report, the base station may determine to handover the UE from using a first relay UE to using a second relay UE. The base station may transmit a handover command to the UE, triggering the remote UE to communicate with the base station via the second relay UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device (WCD) may initiate, based at least in part on a determination to participate in user-equipment-to-user-equipment (U2U) relay communication, a discovery procedure to discover one or more of access to a second WCD or services provided by the second WCD, the second WCD being accessible via a third WCD. The WCD may communicate, for example U2U communications, with the second WCD via the third WCD based at least in part on the discovery procedure. Numerous other aspects are provided.

Abstract: A configuration configuring a UE to establish a connection with one or more candidate relays in preparation of switching to a target relay from one or more candidate relays. The apparatus receives, from a source relay, a candidate relay configuration, the candidate relay configuration including at least information of candidate relays. The apparatus measures a reference signal of the source relay and each of the candidate relays based on the candidate relay configuration. The apparatus establishes a connection with a subset of candidate relays. The apparatus transmits, to the source relay, a measurement report of the reference signal of the subset of candidate relays. The apparatus receives, from the source relay, a relay switch command to switch to a target relay from the subset of candidate relays.
