    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.

    Abstract: The present disclosure provides techniques for configuring the utilization of request-to-send/clear-to-send (RTS/CTS) protocol procedures based on varying conditions at the STA. For example, an AP may identify one or more conditions, when satisfied, may trigger the STA to either enable or disable uplink (UL) transmissions associated with a RTS/CTS protocol procedure. In some aspects, an AP may determine a transmit opportunity (TXOP) threshold for an STA and may determine whether to broadcast a message having the TXOP threshold to multiple STAs including the STA or unicast the message to the STA. An STA may receive a message from an AP having a TXOP threshold and may replace, based on an indication in the received message, a current TXOP threshold in the STA with the TXOP threshold in the received message. The STA may transmit an UL RTS frame in response to a determination that a planned TXOP duration satisfies the TXOP threshold.

    Abstract: The disclosure provides methods and apparatuses for multiple user uplink. One aspect of the disclosure provides a method for wireless communication. The method comprises receiving a trigger frame from an access point indicating a target transmission duration for transmission of a physical layer (PHY) service data unit (PSDU) to the access point. The method also comprises generating an aggregated medium access control (MAC) packet data unit (A-MPDU) frame comprising at least one A-MPDU subframe, the A-MPDU frame having a first length, determining whether an additional A-MPDU subframe having a second length may be added to the A-MPDU frame based at least in part on the first length, the second length, and the target transmission duration, and including one or more padding subframes in the A-MPDU frame based at least in part on a comparison between the first length and the target transmission duration.

    Abstract: Aspects of the present disclosure provide various mechanisms for protection of MU transmissions, such as UL MU MIMO and UL OFDMA. The mechanisms may allow for various NAV setting options for UL MU MIMO or UL OFDMA. Aspects of the present invention relate to a processing system configured to generate a first frame configured to trigger multiple transmissions from multiple devices, wherein the first frame has a duration field set to a value corresponding to a duration that covers at least the multiple transmissions, and an interface configured to output the frame for transmission.

    Abstract: Certain aspects of the present disclosure provide methods and apparatus for enabling an immediate response. In this manner, issues can be avoided where data carried by the last symbol of a frame cannot be entirely decoded by a receiver within a deadline for generating an immediate response. One example method for wireless communications by a first apparatus generally includes determining at least one constraint for communicating with a second apparatus; generating a frame that solicits a response; and outputting the frame for transmission to the second apparatus, wherein at least a last symbol of the frame is transmitted in a manner determined by the constraint to allow the second apparatus to transmit the response within a determined period.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an AP. The AP determines an interference metric of a BSS having a plurality of STAs. The AP is in the BSS. The interference metric indicates a degree of interference in the BSS caused by one or more hidden nodes associated with the plurality of STAs. The AP determines whether the interference metric meets a threshold. The AP transmits, to the plurality of STAs, a frame including an indicator when the interference metric meets the threshold. The indicator indicates to each of the plurality of STAs to enable a medium reserving procedure. The medium reserving procedure reserves a medium for data transmission.
