Abstract: Certain aspects of the present disclosure provide techniques for paging based on a paging early indication (PEI). Particular aspects provide for a method for wireless communication performed by a user equipment (UE). The method generally includes determining a set of paging cycles for receiving paging information from a base station (BS), receiving a first paging early indicator (PEI) from the BS in a first paging cycle of the set of paging cycles, wherein the first PEI indicates whether the paging information will be transmitted to the UE in one or more second paging cycles of the set of paging cycles occurring after the first paging cycle, and receiving the paging information in the one or more second paging cycles based on the first PEI received in the first paging cycle.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay user equipment (UE) may establish a sidelink unicast link with a remote UE via a sidelink signaling interface. The relay UE may identify configuration information for an adaptation layer of the sidelink signaling interface, the configuration information including at least one of a remote UE identifier associated with the sidelink unicast link for a relay service, bearer identifier information identifying one or more bearers between the remote UE and a network entity for the relay service, a radio link control (RLC) channel mapping between a bearer identifier and one or more RLC channels, or data routing information associated with the relay service. The relay UE may relay communications between the remote UE and the network entity based at least in part on the configuration information. Numerous other aspects are described.

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: This disclosure provides systems, methods, apparatus, and computer programs encoded on a computer storage media for providing user equipment mobility history information to a remote computing platform. In one aspect, a user equipment may store user equipment mobility history information in memory within the user equipment. The user equipment may determine whether a radio access network connection state has changed from a primary cell in a radio resource controller state to another cell outside a radio access network, to an inter-radio access technology cell, or to an out of service. The user equipment may transmit the user equipment mobility history information to the remote computing platform in response to determining that the user equipment radio access network connection state has changed from a primary cell in a radio resource controller state to another cell outside a radio access network, an inter-radio access technology cell, or an out of service state.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information related to a dedicated preconfigured uplink resource (DPUR) in a message releasing the UE to an idle mode or an inactive mode. For example, in some aspects, the information related to the DPUR may identify one or more uplink resources that are allocated to the UE to enable the UE to initiate an uplink data transmission in the idle mode or the inactive mode. The UE may transmit, based at least in part on the information related to the DPUR, uplink data while in the idle mode or the inactive mode. Numerous other aspects are provided.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of cell quality measurements for a set of candidate target cells. The UE may select a target cell, from the set of candidate target cells, and a beam, of one or more beams of the target cell, for a conditional handover procedure and based at least in part on the set of cell quality measurements. The UE may perform the conditional handover procedure to transfer from a source cell to the target cell based at least in part on selecting the target cell and the beam. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for grouping demodulation reference signal (DMRS) sequences for uplink transmission without grant based on one or more of cross correlation of sequences, the cubic metric or peak-to-average power ratio (PAPR). In accordance with this technique, the power control for transmissions of DMRS can also be exploited to enhance sequence grouping. Features of the present disclosure may prepare a composite sequence that is generated by concatenating two base sequences. In this instance, the base station may provide UEs with a pool of base sequences. For transmission of DMRS, the UEs may select two base sequences that may be transmitted in two consecutive slots or two DMRS symbols in a slot. By allowing the UE to select two base sequences, the network may reduce the probability of a collision that may occur when two UEs select the same base sequence.

Abstract: A wireless device may receive a first synchronization signal block (SSB) in a radio frequency band of a first cell of a neighbor base station, and report a physical cell identifier (PCI) for the first cell to a serving base station. The serving base station may identify, based on the PCI report, whether a radio frequency band of the first SSB is in or off a synchronization raster, and determine whether to instruct the UE to report a global cell identifier (CGI) for the neighbor base station (e.g., CGI for the neighbor cell) based on the identification. The wireless device may identify CGI based system information obtained from the neighbor cell, system information obtained from a master cell associated with the neighbor base station, system information obtained from CGI broadcast from the neighbor cell, or system information requested from the neighbor cell using dedicated resources, based on the instruction.
