Abstract: An apparatus is disclosed for jammer detection. In example aspects, the apparatus includes a wireless transceiver configured to be connected to multiple antennas. The wireless transceiver is configured to transmit a radar transmit signal using a first antenna of the multiple antennas. The wireless transceiver is also configured to receive a radar receive signal via a second antenna of the multiple antennas, with the radar receive signal associated with the radar transmit signal and comprising a jamming signal component. The wireless transceiver is additionally configured to adjust at least one transmission parameter based on a detected presence of the jamming signal component. The wireless transceiver is further configured to transmit an uplink signal based on the adjusted at least one transmission parameter.

Abstract: In some aspects, a device may detect an occurrence of an event associated with the device. The device may transmit a transmission signal responsive to detecting the occurrence of the event. The device may receive a reception signal that is a reflection of the transmission signal from an object. The device may determine, using at least the reception signal, a characteristic of a movement of the object. The device may determine that the characteristic of the movement is indicative of a gesture designated for controlling a function of the device. The device may control the function of the device responsive to determining that the characteristic of the movement is indicative of the gesture. Numerous other aspects are described.

Abstract: In some aspects, a radar device may receive a plurality of received signals comprising a plurality of reflected frequency modulated continuous wave radar signals and phase noise. The radar device may obtain a frequency-domain representation of the received signals comprising a plurality of frequency-domain spectrums. The radar device may determine a shaped noise component of the frequency-domain representation corresponding to a negative distance portion of the frequency-domain representation. The radar device may determine a shaped decision boundary for target detection based at least in part on the shaped noise component, wherein the shaped decision boundary corresponds to a positive distance portion of the frequency-domain representation. The radar device may detect a radar target based at least in part on the shaped decision boundary. The radar device may perform an action based at least in part on detecting the radar target. Numerous other aspects are described.

Abstract: Techniques and apparatus for enhancing transmission power limits and joint input power limits for transmissions from multiple antenna ports in compliance with radio frequency (RF) exposure limits are described. A method that may be performed by a wireless communication device includes receiving, from a network entity, an uplink grant scheduling an uplink transmission from a set of antennas. The uplink grant indicates a transmission mode for the uplink transmission. A respective transmission power limit is determined for each antenna in the set of antennas, based at least in part on the transmission mode and in compliance with an RF exposure limit. The uplink transmission is sent via the set of antennas according to the respective transmission power limits.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may transmit a frequency-modulated continuous-waveform (FMCW) dual ramp radar signal over a time duration that sweeps from a first frequency to a second frequency and from the second frequency to the first frequency. The wireless device may receive a reflection of the radar signal with a first reflected part that corresponds to the first part of the radar signal and a second reflected part that corresponds to the second part of the radar signal. The wireless device may compare the first reflected part and a time-inverted version of the second reflected part to estimate a noise pattern. The wireless device may perform an action based at least in part on the noise pattern. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure generally relate to a programmable multi-mode digital-to-analog converter (DAC) for generating a frequency-modulated signal. For example, certain aspects provide a circuit for sweeping a frequency of an output signal. The circuit generally includes a DAC having an input coupled to an input path of the circuit and an output coupled to an output path of the circuit, a first mixer selectively incorporated in the input path coupled to the input of the DAC, and a second mixer selectively incorporated in the output path coupled to the output of the DAC.
