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).

Abstract: A method for performing adaptive multi-link aggregation dispatching control in multi-link operation architecture and associated apparatus are provided. The method applicable to a wireless transceiver device within a wireless communications system may include: utilizing the wireless transceiver device to communicate with another device within the wireless communications system to set up multiple links respectively corresponding to multiple predetermined radio frequency bands, to allow the wireless transceiver device and the other device to perform data transmission through the multiple links; and performing a dispatching management procedure to selectively perform dispatching regarding a first link among the multiple links, for transmitting a first physical layer (PHY) protocol data unit (PPDU) corresponding to a block acknowledgment (BA) window through the first link, wherein the dispatching regarding the first link includes temporarily reducing a number of medium access control (MAC) protocol data units (MPDUs) corresponding to the BA window in the first PPDU.
