Abstract: Certain aspects of the present disclosure provide techniques for fast adaptation of transmission properties of sounding reference signal (SRS) resource sets. A method that may be performed by a user equipment (UE) includes receiving sounding reference signal (SRS) configuration information, configuring the UE with one or more SRS resource sets, wherein each of the one or more SRS resource sets comprises one or more SRS resources; receiving signaling comprising a field indicating which of the one or more SRS resources in the one or more SRS resource sets are active and which of the one or more SRS resources in the one or more SRS resources sets are inactive; and transmitting one or more SRSs using only the one or more SRS resources that are active.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) carrying information indicating an updated configuration for the UE, wherein the DCI is associated with a hybrid automatic repeat request (HARQ) process for which HARQ feedback regarding the DCI is disabled. The UE may transmit the HARQ feedback regarding the DCI based at least in part on the DCI carrying the information indicating the updated configuration. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a serving transmission-reception point (TRP), downlink control information (DCI) triggering the UE to measure positioning reference signals (PRS), wherein a code point in the DCI is associated with one or more PRS resources, one or more PRS resource sets, one or more positioning frequency layers, or one or more TRPs, and measures PRS transmitted on the one or more PRS resources, the one or more PRS resource sets, the one or more positioning frequency layers, or the one or more 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: 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 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: In an aspect, a radar controller determines a first transmission configuration for a reference radar signal on a first link from a first base station to a second base station, and a second transmission configuration for at least one target radar signal on at least one second link from the first base station to the second base station, the at least one target radar signal for sensing of at least one target, the first transmission configuration being different than the second transmission configuration. The radar controller transmits the first and second transmission configurations to the first and second base stations. The first base station transmits the reference radar signal and the at least one target radar signal in accordance with the respective transmission configurations.

Abstract: In an aspect, a radar controller determines a radar slot format that configures transmission of a reference radar signal on a first symbol over a first link from a first base station to a second base station followed by at least one target radar signal on at least one second symbol over at least one second link from the first base station to the second base station, and transmits an indication of the radar slot format to the first base station and the second base station. The first base station transmits, and the second base station receives, the reference radar signal and the at least one target radar signal in accordance with the radar slot format.

Abstract: A communications transceiver system that employs self-interference mitigation techniques can detect static objects by using techniques that introduce angular or Doppler diversity. This can include moving Tx and Rx antennas and/or performing beam sweeping. When processing RF sensing data from reflected RF signals, self-interference mitigation techniques can be used and compensation can be made for the movement and/or beam sweeping to allow for both self-interference mitigation and detection of static objects.
