    Abstract: A method and an apparatus for performing beamforming training using time division duplex (TDD) service periods is provided. An initiator device configures slots assigned to a responder device of an existing TDD schedule for the beamforming training. The initiator device transmits one or more packets to trigger an antenna sweep for one or more sectors of a beamforming antenna of the responder device during a first slot of the multiple slots. The first slot is assigned to the responder device for receiving from the initiator device. The responder device performs the antenna sweep for the one or more sectors of the beamforming antenna of the responder device. The responder device transmits to the initiator device an acknowledgement of the antenna sweep in a second slot of the multiple slots assigned to the responder device. The second slot is assigned to the responder device for transmitting to the initiator device.

    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.

    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: 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 methods and apparatus for signaling a receive antenna mode to use during beamforming training procedure. For example, an apparatus for wireless communications, may generally include a processing system configured to generate a first frame having one or more beamforming training fields to be output for transmission to a wireless device using a directional transmit antenna mode and an indication whether the wireless device is to be in an Omnidirectional receive antenna mode to receive the one or more beamforming training fields, and a first interface configured to output the first frame for transmission.
