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: Various aspects of the disclosure relate to co-existence of millimeter wave (mmW) communication and radar. In some aspects, a device that supports mmW communication and radar operations may determine whether or when to conduct radar operations based on information obtained about a nearby mmW network. For example, prior to sending radar signals, the device may monitor for mmW communication signals. As another example, the device may send at least one mmW communication signal to reserve a communication medium for subsequent radar operations. As yet another example, the device may conduct radar operations during idle or allocated time periods defined by the mmW network.

Abstract: A technique is disclosed for reducing interference in a communication system including a plurality of wireless devices. A first device transmits a frame (e.g., an RTS frame or a CTS frame) to a second device, the frame including information from which a non-target third device may use to estimate potential interference at the first device based on a proposed transmission to a fourth device. The information includes at least one of an interference and sensitivity factor (ISF), transmit power, and reciprocity factor (a difference between an antenna receive gain and an antenna transmit gain). Using the information in the frame to estimate the potential interference at the first device, the third device may choose to proceed with the proposed transmission if the estimated potential interference is less than a threshold; or withdraw or modify the proposed transmission if the estimated potential interference is greater than or equal to a threshold.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for enhancing a sector sweep. The apparatus generally includes a processing system configured to generate a first set of frames and a second set of frames. The apparatus also includes a first interface configured to output the first set of frames for transmission to a wireless node via a first set of beams, wherein each beam of the first set is wider in a first dimension than a second dimension, and output the second set of frames for transmission to the wireless node via a second set of beams, wherein each beam of the second set is wider in the second dimension than the first dimension.

Abstract: Certain aspects of the present disclosure provide techniques to reduce address collision in short sector sweeps. In some cases, the techniques involve determining whether an encoded address (e.g., a compressed address), generated using a first parameter (e.g., a seed for a hash function), identifies a first wireless node and a second wireless node as a same destination for at least one first frame including the encoded address; generating at least one second frame including an indication not to use the first parameter if the encoded address identifies the first wireless node and the second wireless node as the same destination; and outputting the at least one second frame for transmission to at least one of the first wireless node or the second wireless node.
