Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) reports, to a network entity, a minimum number of symbols of a positioning reference signal (PRS) resource of a first transmission-reception point (TRP) of a pair of TRPs based on a reference signal time difference (RSTD) uncertainty parameter for the pair of TRPs, wherein the minimum number of symbols is less than a total number of symbols allocated for the PRS resource, and performs a positioning measurement of the minimum number of symbols of the PRS resource.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive, from a network entity, a request to provide an enhanced positioning measurement report comprising a positioning measurement and further comprising a report of components of a channel power delay profile (PDP), a report of a probability distribution of times of arrival (ToA), or both. The UE may determine an enhanced measurement period required by the UE to perform the enhanced positioning measurement, wherein the enhanced measurement period is longer than a standard measurement period required by the UE to perform a non-enhanced positioning measurement. The UE may perform the enhanced positioning measurement using the enhanced measurement period. The UE may provide the enhanced positioning measurement report to the network entity.

Abstract: A method of providing positioning state information in a channel usable for conveying the positioning state information includes: obtaining a positioning state information resource allocation parameter; determining a positioning resource amount based on the positioning state information resource allocation parameter, the positioning resource amount being an amount of resources of the channel usable for conveying the positioning state information; and transmitting the positioning state information over the channel while occupying no more than the positioning resource amount of resources of the channel.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) performs at least one positioning measurement of at least one downlink positioning reference signal (DL-PRS) received from a transmission-reception point (TRP) during a positioning session, reports, to a positioning entity, a value of the at least one positioning measurement via low layer signaling, and determines a timestamp for the at least one positioning measurement relative to a reference point, wherein the timestamp comprises an amount of time between the reference point and a time at which the at least one positioning measurement is valid.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) performs at least one positioning procedure with at least one transmission-reception point (TRP), and transmits a positioning report for the at least one positioning procedure via first low layer signaling or both the first low layer signaling and second signaling different than the first low layer signaling.

Abstract: In an embodiment, a first node (e.g., a UE or a BS) performs a channel response measurement on a reference signal for positioning (e.g., UL reference signal such as SRS for positioning, or a DL PRS). The first node determines, for each of a plurality of peaks detected within the channel response measurement, peak-specific information comprising at least peak magnitude data that is based on a peak magnitude relative to a reference value. The first node reports the peak-specific information for the plurality of peaks to a second node (e.g., a BS, UE, or LMF). The second node receives the peak-specific information, and determines a positioning estimate for a UE based on the peak-specific information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive scheduling information that schedules a physical downlink shared channel (PDSCH) communication for the UE; and select a downlink beam for reception of the PDSCH communication from a set of usable downlink beams associated with an uplink beam to be used by the UE for uplink transmission in one or more symbols in which the PDSCH communication is scheduled. Numerous other aspects are provided.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a reduced-capability user equipment (UE) receives, from each of one or more premium UEs, one or more parameters indicating a quality of a location estimate of the premium UE, selects at least one premium UE based on the quality of the location estimate of the at least one premium UE, and derives a location estimate of the reduced-capability UE based on the location estimate of the at least one premium UE. In another aspect, a reduced-capability UE transmits, to at least one premium UE, a request to perform one or more positioning measurements of one or more downlink reference signals, receives, from the at least one premium UE, a measurement report comprising the one or more positioning measurements, and determines a location estimate of the reduced-capability UE based on the one or more positioning measurements in the measurement report.

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.
