Abstract: This disclosure provides methods, devices and systems for increasing carrier frequencies for wireless communications in wireless local area networks. Some implementations more specifically relate to beamforming training operations that support wireless communications on carrier frequencies above 7 GHz. In some aspects, a beamforming initiator may initiate a beamforming training operation by transmitting a number (N) of beamforming training (BFT) packets in N TX beam directions, respectively, on a carrier frequency above 7 GHz. The beamforming responder receives one or more of the BFT packets and provides feedback to the beamforming initiator indicating the TX beam direction associated with the BFT packet having the highest received signal power. In some aspects, the beamforming responder may train its RX antennas for RX beamforming concurrently while the beamforming initiator trains its TX antennas. In some other aspects, the beamforming responder may train its RX antennas after the beamforming initiator trains its TX antennas.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for multistatic radar communications. In one aspect, a wireless communication device may determine a distance and direction of one or more receiving devices. The wireless communication device may transmit, to the one or more receiving devices, timing information indicating a timing relationship between a codeword sequence and one or more pulses. The wireless communication device may transmit a respective codeword of the codeword sequence in the direction of each of the one or more receiving devices. The wireless communication device may further transmit the one or more pulses in a plurality of directions. The wireless communication device may receive feedback from at least one of the one or more receiving devices and determine ranging information about an object based on the feedback and the distance or direction of at least one receiving device.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for generating frames with dual mode channel estimation fields (CEFs) that may accommodate devices with different processing capabilities. In some examples, a frame that is generated comprises a first portion for transmission on separate channels, and a second portion for transmission using channel bonding. The second portion has a training field including first complementary sequences, a first channel estimation field (CEF) including second complementary sequences, and a second CEF including one of the first complementary sequences of the training field and a subset of the second complementary sequences of the first CEF.

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.
