Abstract: Disclosed are techniques for group reporting of UE receive-transmit (Rx-Tx) time difference measurements for multi-RTT positioning. A plurality of downlink reference signals (DL RSs) are received from a plurality of transmission reception points (TRPs). A corresponding plurality of uplink reference signals (UL RSs) are transmitted to the plurality of TRPs. One or more numerology factors are determined for the plurality of TRPs. A measurement report is generated for the plurality of TRPs based on the numerology factors. The measurement report is transmitted to a network entity. The measurement report includes UE receive-transmit (Rx-Tx) time difference measurements for at least two of the TRPs.

Abstract: In an aspect, a wireless node (e.g., UE, gNB) performs a partial measurement of a measurement type (e.g., RSTD, Rx-Tx, etc.) of a reference signal for positioning (RS-P) resource (e.g., PRS, SRS) that includes multiple symbols, the partial measurement being measured across a subset of the multiple symbols. The wireless node transmits a measurement report that includes an indication of the first partial measurement. The communications device receives the measurement report, and determines whether a spoofing attack is associated with the RS-P based at least in part upon the measurement report.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sounding reference signal (SRS) on a first set of sub-bands (305). The UE may report channel state information (CSI) associated with a second set of sub-bands (310). The first set of sub-bands may be different from the second set of sub-bands. The CSI may include information that identifies one or more frequency domain correlations among the first set of sub-bands and the second set of sub-bands. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE receives a positioning configuration, the positioning configuration including at least an identifier of a first downlink reference signal from a neighboring cell to be used for estimating a downlink path loss or determining an uplink spatial transmit beam, determines that a first downlink reference signal received from the neighboring cell cannot be used for estimating the downlink path loss or determining the uplink spatial transmit beam, in response to the determination, estimating the downlink path loss or determining the uplink spatial transmit beam based on a second downlink reference signal received from the neighboring cell or a serving cell, and transmits an uplink reference signal for positioning based on the estimated downlink path loss, the determined uplink spatial transmit beam, or a combination thereof.

Abstract: Techniques are disclosed for determining the location of an object using RF sensing. More specifically, an object may be detected in a wireless data communication network using radar techniques in which one or more base stations act as a transmitter and a mobile device (e.g., a user equipment (UE)) acts as a receiver in a bistatic or multi-static radar configuration. By comparing the time a line-of-sight (LOS) signal is received by the mobile device with that of an echo signal from a reflection of an RF signal from the object, a position of the object can be determined. Depending on desired functionality, this position can be determined by the UE, or by a network entity.

Abstract: In an aspect, a network entity may receive download control information (DCI) indicating a first scrambling identification value, a second scrambling identification value, and a scrambling selection value, wherein the scrambling selection value has either a first scrambling selection value or a second scrambling selection value. The network entity may configure a first demodulation reference signal (DMRS) symbol sequence based on a first initial seed value, a second DMRS symbol sequence based on a second initial seed value, and a third DMRS symbol sequence based on a third initial seed value. The network entity may be configured, based on the scrambling selection value, to transmit or receive DMRS on a group of code division multiplexed (CDM) antenna ports based on either the first DMRS symbol sequence, the second DMRS symbol sequence, or the third DMRS symbol sequence.

Abstract: Certain aspects of the present disclosure provide techniques for configuring parameters for small data transfer (SDT) transmissions. One example technique provides a method for wireless communications at a user equipment (UE), involving: obtaining configuration information received from a network entity, the configuration information indicating a plurality of configurations for small data transfer (SDT) transmission, determining at least one of a transport block size (TBS) or data threshold for SDT transmission based on one of the configurations, and outputting for transmission one or more SDT transmissions based on the determination.

Abstract: In an aspect, a radar controller determines transmission configuration(s) for target radar signals from a first wireless communications device to a second wireless communications device, the target radar signals for sensing of at least one target, the at least one transmission configuration configuring a first time-domain section associated with a first time-domain target radar signal density, and a second time-domain section associated with a second time-domain target radar signal density that is different than the first time-domain target radar signal density. The radar controller transmits the transmission configuration(s) to the first and second wireless communications devices. The first wireless communications device transmits the target radar signals to the second wireless communications device in accordance with the transmission configuration(s).

Abstract: A design is provided for spatially multiplexing uplink channels. A user equipment (UE) detects that a Physical Uplink Control Channel (PUCCH) and a Sounding Reference Signal (SRS) are to be transmitted simultaneously. The UE decides to spatially multiplex the PUCCH and the SRS for simultaneous transmission via different sets of one or more antennas. The UE determines time and frequency resources for the PUCCH and the SRS to avoid collision of at least a portion of the PUCCH with the SRS. The UE transmits the spatially multiplexed PUCCH and SRS using the determined time and frequency resources.
