Abstract: Methods, systems, and devices for wireless communications are described in which user equipment (UE) may provide a capability indication to one or multiple transmission reception points (TRPs) that indicates whether the UE is capable of performing Doppler pre-compensation. One or more of the TRPs may transmit configuration information to the UE to configure Doppler pre-compensation for subsequent communications. The UE may indicate that multiple Doppler shifts for a single communication with multiple TRPs is supported, or that a single Doppler shift or no Doppler shift is supported. The UE, when Doppler pre-compensation is supported and configured, may estimate one or more Doppler metrics (e.g., a Doppler shift, a maximum Doppler spread, or both) for one or multiple TRPs based on one or more reference signals from the TRPs, and may transmit one or more uplink communications based on the estimated Doppler metrics.

Abstract: A mobile device can report its capabilities to a network node regarding one or more phase characteristics between Sounding Resource Signal (SRS) resources transmitted by the mobile device under one or more circumstances, enabling the network to configure the mobile device accordingly. Such reporting can enable the network to coherently process multiple SRS resources, effectively increasing the bandwidth of the SRS resources and, ultimately, the accuracy of a position determination for the mobile device. Various techniques are provided for reporting capabilities and determining applicable conditions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, to a base station, an indication of a selected random access channel (RACH) procedure that is selected based at least in part on positioning state information (PSI) associated with the UE, wherein the PSI is based at least in part on one or more positioning measurements obtained by the UE; and receive, from the base station, a configuration of resources for the selected RACH procedure. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use cover coding for sounding reference signal (SRS) resources for performing antenna switching. The UE may receive a configuration for a reference signal resource set for transmitting a reference signal for antenna switching, the configuration including an indication of a type of time division cover coding for repetitions of the reference signal and an indication of a type of frequency hopping. The UE may determine a reference signal resource for transmission of the reference signal based on the configuration and the type of frequency hopping. The UE may then transmit a set of repetitions of the reference signal over the determined reference signal resource according to the type of time division cover coding.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a demodulation reference signal (DMRS) and a physical downlink shared channel (PDSCH) associated with the DMRS, the DMRS and the PDSCH spanning a plurality of symbols of a slot, decodes the PDSCH, performs a positioning measurement based on the DMRS and the decoded PDSCH, and reports, to a location server, the positioning measurement or location information derived at least based on the positioning measurement.

Abstract: Certain aspects of the present disclosure provide techniques for securing physical (PHY) layers in wireless communication. Certain aspects are directed to a method for wireless communication by a user equipment (UE). In some examples, the method includes obtaining a key and using the key during physical layer signal processing of a physical uplink control channel (PUCCH) transmission having more than one symbol to provide security for the PUCCH transmission.

Abstract: Disclosed are techniques for wireless communication. In an aspect, BS determines a channel state information (CSI) report field priority-based security scheme, and transmits CSI report field priority-based security scheme to UE. UE determines bit availability in CI (e.g., UCI or SCI or MAC CE) for transmission of a CSI report. UE configures, based on the CSI report field priority-based security scheme and the CI bit availability, the CSI report with first field(s) (e.g., secured with key) being secured via a key and second field(s) being unsecured (e.g., not secured with any key or secured with weaker key below strength threshold). UE transmits the CSI report to BS.
