Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first downlink control information (DCI) message of a two-stage set of DCI. The UE may receive, from the base station, a second DCI message of the two-stage set of DCI. The UE may select between the first DCI message and the second DCI message as a timing reference point. In some examples, the UE may receive, from the base station, downlink data on the physical downlink channel. In some examples, the UE may transmit, to the base station, an uplink data message on the physical uplink channel.

Abstract: Disclosed are techniques for communication. In an aspect, a position estimation entity determines a sidelink positioning reference signal (SL-PRS) resource configuration associated with a positioning measurement procedure. The position estimation entity transmits an indication of the SL-PRS resource configuration (e.g., to first and/or second UEs). The UE(s) obtain the SL-PRS resource configuration, and perform the positioning measurement procedure in accordance with the SL-PRS resource configuration.

Abstract: Disclosed are techniques for communication. In an aspect, a position estimation entity (e.g., gNB, LMF, location server, UE, etc.) determines a paired downlink positioning reference signal (DL-PRS) resource configuration for a first DL-PRS and a second DL-PRS that is offset in time from the first DL-PRS by a time offset, the first and second DL-PRSs associated with the same transmission source. The position estimation entity transmits the paired DL-PRS resource configuration to a UE, which performs measurements in accordance with the paired DL-PRS resource configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a UE capability message, the UE capability message indicating a supported transmit antenna switching (TxAS) capability for each port of the UE. The UE may receive a configuration message indicating an uplink multiple-input/multiple-output (UL MIMO) configuration for the UE, the UL MIMO configuration being based at least in part on the UE capability message. The UE may identify, based at least in part on the configuration message, a sounding reference signal (SRS) configuration to use for transmitting SRSs in conjunction with the UL MIMO communications, the SRS configuration comprising a configuration for transmission by the UE of SRSs using at least one of the two or more ports of the UE, the SRSs transmitted on one or more antennas of the UE selected according to a TxAS configuration for the respective port.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an assisting user equipment (UE) may determine, within a resource selection window, one or more resources to reserve in a shared resource pool for an internal sidelink transmission within a disaggregated UE group including the assisting UE and one or more assisted UEs. The assisting UE may transmit, over a sidelink, an assisting reservation message indicating a lower reference signal received power (RSRP) to project onto the one or more resources reserved for the internal sidelink transmission relative to a measured RSRP that is based at least in part on a transmit power associated with the assisting reservation message. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit a trigger message to a second UE, where the trigger message triggers a channel state information (CSI) report that includes a first CSI reporting mode of a set of CSI reporting modes and a reporting quantity for the first CSI reporting mode. For a first reporting quantity, the first UE may trigger the second UE to transmit a CSI reference signal (RS), and the first UE may then receive the CSI-RS to determine CSI based on the CSI-RS. Additionally or alternatively, for other reporting quantities, the first UE may transmit the CSI-RS to the second UE, and the second UE may transmit channel state feedback to the first UE based on measuring CSI for the received CSI-RS, where the first UE determines the CSI based on the channel state feedback.

Abstract: The present disclosure relates to uplink control information (UCI) multiplexing for multi-slot physical uplink shared channel (PUSCH) with transport block size (TBS) scaling. Specifically, a user equipment (UE) may determine to transmit UCI on a multi-slot PUSCH transmission. The UE may further identify a number of UCI resource elements (REs) in at least one slot of the PUSCH transmission based at least on a scaling rate. The UE may further perform the PUSCH transmission including the UCI REs.
