Abstract: Aspects relate to sidelink channel tracking using quasi co-location (QCL) information for a sidelink channel between wireless communication devices (e.g., UEs). A transmitting UE may identify the QCL information for a sidelink transmission to a receiving UE over the sidelink channel and transmit an indication of the QCL information to the receiving UE. The indication of the QCL information may be representative of one or more large-scale channel properties (LSCPs) associated with the sidelink transmission. The receiving UE may then process the sidelink transmission based on the one or more LSCPs.

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: Techniques for communication by a user equipment (UE) are disclosed. Techniques can include determining a positioning state information (PSI) report to transmit, where the PSI report comprises positioning-related information, and selecting a physical uplink control channel (PUCCH) resource with which to transmit the PSI report, where the selected PUCCH resource comprises a number of resource blocks (RBS). Techniques can further include determining whether to transmit the PSI report using the selected PUCCH resource, based on: the number of RBS, a size of uplink control information (UCI) to be transmitted using the selected PUCCH resource, the selected PUCCH resource being configured with a capability to include both the PSI report and a hybrid automatic repeat request acknowledgment (HARQ-ACK), or the selected PUCCH resource being configured to include only one or more PSI reports, and optionally one or more CSI reports, as a payload, or any combination thereof.

Abstract: Techniques for reconfigurable intelligent surface (RIS)-assisted calibration for timing errors in wireless nodes may comprise obtaining a set of wireless reference signal measurements comprising: first, second, third, and fourth measurements of reference signals traveling between the mobile device, a first wireless node, and a second wireless node, wherein a portion of the reference signals are reflected by the RIS while traveling between the mobile device and the first or second wireless node. A differential value comprising a difference between the third measurement and the fourth measurement is also obtained. Determining a position estimate of the mobile device may then be performed, based at least in part on the set of wireless reference signal measurements, the differential value, and a respective location of each of the first wireless node, the second wireless node, and the RIS.
