Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration of a control region in a delay-Doppler domain. The UE may receive, from the base station, a physical downlink control channel (PDCCH) communication with orthogonal time frequency space (OTFS) precoding. The UE may decode the PDCCH communication with OTFS precoding based at least in part on the configuration of the control region in the delay-Doppler domain. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive an announcement message from each sidelink anchor device of one or more sidelink anchor devices, wherein the announcement message includes a sidelink anchor device identifier and an indication that the sidelink anchor device is available for positioning services. The UE may measure the announcement message from each sidelink anchor device to determine a signal strength measurement associated with the sidelink anchor device. The UE may report, to a network node, one or more preferred sidelink anchor devices from the one or more sidelink anchor devices, wherein the one or more preferred sidelink anchor devices are determined based on the signal strength measurement respectively associated with each sidelink anchor device of the one or more sidelink anchor devices.

Abstract: Techniques are provided for aligning radio frequency (RF) sensing operations with base station discontinuous reception (DRX) and discontinuous transmission (DTX) cycles. An example method for performing RF sensing operations with a wireless node according to the disclosure includes receiving discontinuous reception or discontinuous transmission information for the wireless node, determining one or more on periods and one or more off periods based on the discontinuous reception or the discontinuous transmission information, performing radio frequency sensing operations with the wireless node during the one or more on periods, and ceasing radio frequency sensing operations with the wireless node during the one or more off periods.

Abstract: In an aspect, a wireless node performs a first RSRP measurement of an RS-P based on a first set of samples within a first time window of an RS-P symbol or resource, and determines whether a spoofing attack is associated with RS-P based on the first RSRP measurement and one or more other RSRP measurements of one or more other sets of samples within one or more earlier time windows of the RS-P symbol or resource. The wireless node transmits, to a communications device (e.g., position estimation entity), an indication (e.g., in a measurement report) of the spoofing attack determination. The communications device performs at least one action based at least in part upon the indication of the spoofing attack determination.

Abstract: Aspects presented herein may enhance the efficiency and performance of RF sensing schemes/mechanisms based at least in part on time and frequency domain muting. In one aspect, a base station transmits, to a plurality of TRPs, a TRP configuration to configure the plurality of TRPs to transmit one or more RRSs over multiple transmission occasions based on a frequency band. The base station transmits, to the plurality of TRPs, an indication to mute at least one of a first sub-band or a second sub-band of the frequency band for transmitting the one or more RRSs in each of the multiple transmission occasions.
