Abstract: A target user equipment (UE) may receive, from each relay UE of a set of relay UEs, a synchronization signal block (SSB) through each transmit beam of a set of transmit beams from the UE through each receive beam of a set of receive beams at the target UE. The relay UE may transmit the paging message through each transmit beam of the set of transmit beams. The target UE may determine a beam pair based on the received SSB, and receive the paging messaged using the beam pair. The target UE may also receive, from a relay UE, a paging message through one or more sidelink channels from each transmit beam of a set of transmit beams of the relay UE through each receive beam of a set of receive beams at the target UE and decode the received paging message.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

Abstract: Certain aspects of the present disclosure provide techniques for resource allocation and hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback for multi-cell scheduling. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a configuration for a plurality of carriers, receiving, from the BS, control information indicating whether resources for a data channel are allocated in a concatenated pair of carriers of the plurality of carriers, and communicating on the data channel with the BS based on the control information.

Abstract: Certain aspects of the present disclosure provide techniques for techniques for bandwidth part (BWP) operations when a user equipment (UE) is configured with multi-cell physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) scheduling. A method that may be performed by a UE includes receiving, from a base station (BS), first downlink control information (DCI) indicating whether resources are allocated for at least one data channel on multiple carriers, the first DCI configuring at least one BWP configuration to be activated on the multiple carriers, interpreting the first DCI based on the at least one BWP configuration to be activated, and communicating with the BS in accordance with the first DCI as interpreted based on the at least one BWP configuration.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) identifies a set of positioning sources, each positioning source comprising a positioning reference signal (PRS) resource, a PRS resource set, a PRS frequency layer, and/or a transmission/reception point (TRP). From the set of positioning sources, the UE identifies a consistency group comprising a collection of positioning sources grouped based on expected values of at least one metric of a reference signal from each positioning source, measured values of the at least one metric for the reference signal from each positioning source, and an error threshold. The UE identifies one or more subsets of positioning sources within the consistency group, each subset having at least one metric error value. The UE reports, to a network entity, information about the consistency group and information about at least one of the subsets of positioning sources within the consistency group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure sidelink control information (SCI) to indicate a plurality of sidelink transmission opportunities that are to be reserved for the UE. The UE may transmit the SCI to one or more other UEs. 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 transmit, to a base station, a report that includes measurements associated with one or more downlink reference signals that are received using a set of candidate downlink beams. The UE may transmit one or more uplink reference signals using a set of candidate uplink beams. The UE may receive, from the base station, information that indicates, among the set of candidate downlink beams and the set of candidate uplink beams, a best uplink beam to use for one or more uplink transmissions. For example, the base station may select the best uplink beam based at least in part on the measurements associated with the one or more downlink reference signals and measurements associated with the one or more uplink reference signals. Numerous other aspects are provided.

Abstract: When a user equipment (UE) is configured with a primary cell (PCell) and one or more secondary cells (SCell), scheduling of uplink (UL) and/or downlink (DL) resources for the UE may be received from the primary cell. However, in some circumstances, the primary cell may be unable to provide such scheduling related information. In such circumstances, one or more secondary cells may be enabled to provide scheduling related information to the UE such that cells other than the primary cell may function as scheduling cells. Information regarding dormancy states of the cells (primary and/or secondary) may also be provided by the scheduling cells.
