Abstract: Certain aspects of the present disclosure provide methods and apparatus for enhancing a beamforming training procedure. For example, an apparatus can include a processing system that generates a plurality of transmit beamforming refinement frames for a transmit sector sweep that each include a preamble, a data field, at least one beamforming training field, identification of a transmit antenna array to be used for transmitting the at least one beamforming training field, and a status indication of whether the transmit beamforming refinement frame is a last transmit beamforming refinement frame in the transmit sector sweep for one or more receive antenna arrays of a wireless node. The apparatus also includes a first interface that outputs the transmit beamforming refinement frames using a first transmit beamforming sector for the preambles and data fields, and one or more second transmit beamforming sectors for subfields of the beamforming training fields.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for multistatic radar communications. In some implementations, a transmitting device may transmit, to a receiving device, a radar alert frame followed by a codeword and one or more radar pulses. The radar pulses are transmitted, using beamforming, in a number of directions. The timing information indicates a timing offset or delay between one or more codewords of the codeword sequence and the beginning of the radar pulses. The receiving device may detect one or more codewords of the codeword sequence and an echo of at least one of the radar pulses, and determine the time at which the corresponding pulse was transmitted by the transmitting device. The receiving device may compare the timing of the echo with the timing of the transmitted pulse to determine a relative distance of an object that produced the echo.

Abstract: This disclosure provides methods, devices and systems for radio frequency (RF) sensing in wireless communication systems. In some implementations, a transmitter device transmits sounding sequences configured for channel estimation over a wireless channel to a receiver device. The transmitter device also transmits or receives non-sounding frames associated with a channel report of the receiver device. The transmitter device transmits a frame soliciting the channel report from the receiver device. The transmitter device receives the channel report, which may include channel state information (CSI) of the wireless channel responsive to at least the sounding sequences. Some types of channel reports may take longer to generate than other types of channel reports. Transmitting or receiving the non-sounding frames during the time period may prevent other devices from accessing the wireless channel when the receiver device needs additional time to generate a certain type of channel report.

Abstract: In some implementations, an initiator device establishes a measurement session with each of a plurality of responder devices based at least in part on their capabilities. The initiator device negotiates, with each of the responder devices, a respective set of one or more sensing parameters based at least in part on the capabilities of the initiator device and the capabilities of the respective responder device, the respective sets of sensing parameters associated with the responder devices being identified by a unique Measurement Setup identifier (ID). The initiator device performs one or more measurement instances with the responder devices based on the respective sets of sensing parameters, each measurement instance identified by a unique Measurement Instance ID and the respective Measurement Setup ID. The initiator device obtains, from each responder device, one or more measurement reports indicating channel state information (CSI) based on the one or more respective measurement instances.
