Abstract: Methods, systems, and devices for remote user equipment (UE) discovery and link establishment for reduced capability UE are described. In some examples, a relay UE may transmit one or more discovery messages associated with establishing a sidelink relay communication link between the relay UE and a remote UE having a reduced communication bandwidth capability relative to the relay UE. In such examples, the relay UE may perform a communication bandwidth configuration procedure with the remote UE based on the remote UE having the reduced communication bandwidth capability relative to the relay UE. In some examples, the relay UE and the remote UE may establish, in accordance with the communication bandwidth configuration procedure, the sidelink relay communication link between the relay UE and the remote UE using a reduced communication bandwidth that is less than a full communication bandwidth allocated for the relay UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information identifying multiple remote UEs for which the UE serves as a relay UE. The UE may receive, from the base station, an indication of a grouping of the remote UEs into one or more paging groups. The UE may monitor, for each paging group of the one or more paging groups, paging occasions associated with that paging group to determine whether paging messages for the remote UEs in that paging group are received from the base station. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing measurements and other functions in preparation for communicating with a base station on a secondary cell (SCell). In particular, a user equipment (UE) may switch to a certain bandwidth part (BWP) (e.g., a dormant BWP) on an SCell when the SCell is deactivated, and the UE may perform the appropriate measurements and functions on this BWP (e.g., based on reference signals received on this BWP). In some cases, the UE may determine to switch to the BWP for performing the appropriate measurements and functions based on an inactivity timer expiring or based on an indication from a base station (e.g., on a primary cell (PCell)). Accordingly, once the UE activates the SCell for communications with a base station, the latency associated with preparing for communicating on the SCell may be reduced.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may transmit, to a base station, a first uplink message including one or both of a protocol layer source identifier associated with a second UE or a request for a local identifier associated with the second UE. The first UE may receive, from the base station, a first downlink message including a downlink signal radio bearer (DL SRB) message, and the DL SRB message including one or both of the protocol layer source identifier associated with the second UE or the local identifier associated with the second UE in a downlink adaptation layer header of the DL SRB message. The first UE may transmit, to the second UE, in a sidelink adaptation layer header of a sidelink message, the local identifier associated with the second UE based in part on the received first downlink message.

Abstract: Methods, systems, and devices for wireless communications are described. A remote user equipment (UE) may establish a first connection with a relay UE that is in communication with a base station via a second connection. The first connection may be of a first connection type and the second connection may be of a second connection type. The remote UE may identify a mapping between one or more first quality of service (QOS) parameters corresponding to the first connection type and one or more second QoS parameters corresponding to the second connection type. The remote UE may determine, using the mapping, a first QoS parameter to be applied to the first connection as part of an end-to-end (E2E) connection with the base station via the relay UE, and communicate with the base station via the relay UE using the E2E connection.

Abstract: Certain aspects of the present disclosure provide techniques for determining a timing advance (TA) for a handover in a network, such as a non-terrestrial network, A method that may be performed the UE includes receiving, from a source base station (BS), a handover command instructing the UE to hand over to a target BS, obtaining an indication of a timing advance (TA) for communicating with the target BS, wherein the indication of the TA for communicating with the target BS is based, at least in part, on a TA used for communicating with the source BS and a first time difference between a first reference signal associated with the source BS and a second reference signal associated with the target BS, and transmitting, based on the handover command, one or more signals to the target BS using the TA for communicating with the target BS.

Abstract: To facilitate delivery of paging for remote UE, methods, apparatuses, and computer program products are provided. An example method of UE includes receiving, via a sidelink interface from a second UE, paging information. The example method further includes transmitting, to a base station, the paging information. The example method further includes receiving, from the base station, a RRC message comprising a paging record of at least one UE including the second UE. The example method further includes transmitting the paging record to the at least one UE including the second UE via the sidelink interface.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network entity may receive, from a relay node via a radio access link, information indicating a link layer identifier of the relay node associated with a relay service, wherein the relay node is associated with a radio access identifier. The network entity may configure a relay service with the relay node and a remote node using a mapping between the radio access identifier and the link layer identifier. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify a relay pairing between a user equipment (UE) and a relay UE. The base station may additionally identify a configuration of the relay UE based on a handover decision associated with the relay pairing. The base station may indicate, to the UE, the configuration of the relay UE, an identifier of the relay UE, and that the UE is to switch to a sidelink communications link with the relay UE. The UE may then establish the sidelink communications link with the relay UE and may indicate, to the relay UE, that the sidelink communication link is for a handover associated with the relay pairing. Based on receiving the indication that the sidelink communication link is for the handover associated with the relay pairing, the relay UE may perform a connection setup procedure with the base station.

Abstract: Aspects of the disclosure relate to random access procedures. An apparatus (e.g., a user equipment) may identify one or more network slices based on at least one of an access category of the apparatus, an identifier of the one or more network slices, or an index value of the one or more network slices. The apparatus may select a random access channel (RACH) configuration from a set of RACH configurations based on at least one of an access identity of the apparatus or the identified one or more network slices. The apparatus may transmit a random access message based on the RACH configuration.
