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.

Abstract: Methods and apparatus for resource allocation for radio frequency (RF) sensing signals in data communications systems are provided. In some embodiments, a transmitter may determine one or more capabilities associated with a multiple input, multiple output (MIMO) antenna of the transmitter, send information relating to the capabilities to a network entity (e.g., server) of the network, obtain configuration data relating to an allocation of frequency resources for a RF sensing signal (e.g., radar reference signal) interleaved with respect to a plurality of antenna ports associated with the MIMO antenna, and transmit the RF sensing signal in accordance with the configuration data. The obtained data may be configured based on the capabilities. The frequency resources may be orthogonal frequency-division multiplexing (OFDM) resources. According to different embodiments, allocation of OFDM resources may be equidistant, non-equidistant, or on demand (e.g., as requested by the server or confirmed by the server).

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) obtains, from a first cell, a first downlink reference timing and a first reference signal received power (RSRP) measurement, wherein the first RSRP measurement is a first reference RSRP, determines that the first downlink reference timing has changed based on a cell reselection from the first cell to the second cell performed while in a radio resource control (RRC) non-connected state, and obtains, from the second cell, while in the RRC non-connected state, based on the first downlink reference timing having changed more than a threshold, a second downlink timing and a second RSRP measurement, wherein the second RSRP measurement is a second reference RSRP.

Abstract: A network node supports position measurement determination for a user equipment (UE) by prioritizing positioning reference signal (PRS) resource measurements to be included in a location information report based on multipath characteristics of the PRS resources. The network node, for example, may be the UE, a base station, or a sidelink UE. The PRS resource measurements may be prioritized by determining a subset of available PRS resource measurements to include in and/or the order of inclusion in the location information report. The multipath characteristics of each PRS resource may be the number, a strength metric, or a time domain span of the multipath components, or any combination thereof. A location server may request the prioritization of the PRS resource measurements based on the multipath characteristics of the PRS resources and may use the order of the PRS resource measurements in the position determination for the UE.

Abstract: In an aspect, a target user equipment performs positioning. For example, the target user equipment receives a control message from a network entity. The control message identifies a set of measurement time windows in which to perform measurements of one or more signals. The target user equipment performs the measurements of the one or more signals within the set of measurement time windows and transmits a measurement report to the network entity. The measurement report comprises the measurements of the one or more signals performed within the set of measurement time windows.

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: In an aspect, a wireless node performs measurements of an RS-P (e.g., PRS or SRS-P) on different sub-bands of an RS-P resource. The wireless node transmits separate indications of the measurements in a measurement report to a position estimation entity. The position estimation entity determines a positioning estimate of the UE based in part on the measurement report.

Abstract: Positioning assistance data is broadcast by Transmission Reception Points (TRPs) that includes information that is specific for aerial user equipment (UEs) and information that is for terrestrial UEs. The positioning assistance data may be included in positioning System Information Blocks (posSIBs), and the information for the aerial UEs and information for the terrestrial UEs may be provided together in the posSIB or may be provided in separate posSIBs. The positioning assistance data, for example, may separately list, e.g., the TRPs, resource sets, or resources to be used for positioning aerial UEs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a security key generation procedure configuration using control messaging. In accordance with the security key generation procedure, the UE may transmit a sounding reference signal to the base station using one or more first antennas of a plurality of antennas configured at the UE. The UE may receive, from the base station, a downlink reference signal using the one or more first antennas and determine one or more eigenvalues or eigenvectors based on a channel estimation associated with the downlink reference signal. The UE may use the one or more eigenvalues or eigenvectors to derive a security key that is used to secure communications between the base station and the UE.
