Abstract: Techniques pertaining to trigger-based (TB) implicit feedback for implicit beamforming in wireless communications are described. An apparatus (e.g., an access point (AP)) triggers each of one or more stations (STAs) to transmit a respective feedback. The apparatus estimates a respective steering matrix with respect to each of the one or more STAs based on the respective feedback. The apparatus then transmits a respective steered data to each of the one or more STAs based on the respective steering matrix.

Abstract: A method for reducing sounding overhead by shortening TB-PPDU duration for trigger-based implicit feedback and associated apparatus are provided, where a non-AP STA device is wirelessly linking to an AP device, and a number of sounding dimension of the non-AP STA device is less than a maximum number of spatial streams of the AP device. The method may include: transmitting a first frame regarding TB-sounding as well as a trigger frame, with at least one field of at least one frame among the first frame and the trigger frame being set to shorten the TB-PPDU duration; and receiving a sounding feedback having the TB-PPDU duration to be the trigger-based implicit feedback, for use of generating a beamforming steering matrix for transmission beamforming, wherein the at least one field is set to shorten a time for receiving a useless part within the sounding feedback, for reducing the sounding overhead.

Abstract: Techniques pertaining to anti-motion and anti-interference frame exchange sequences in wireless communications are described. A station (STA), such as a Wi-Fi equipment, determines to enable a frame exchange sequence (FES). The STA then communicates with one or more other STAs by utilizing the FES in which preamble puncturing sounding and data transmission are performed in a same transmission opportunity (TXOP).
