Abstract: The application discloses a device and method for beamforming. The beamforming method comprises: sending a null data packet announcement (NDPA) frame from a beamformer to a pseudo user and a target user to indicate the target user to prepare for channel estimation; sending a null data packet (NDP) from the beamformer to the target user and performing channel estimation by the target user based on the NDP to determine channel state information; sending a beamforming report poll (BRP) trigger frame from the beamformer to the target user to trigger the target user to feed back channel state information; and sending from the target user a beamforming report to the beamformer, wherein the beamforming report including the channel state information.

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: 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: Duplicated packet transmission methods are provided. The duplicated packet transmission method may include the following steps. A sender may determine whether to pad at least one duplicated packet into a multi-user physical-protocol-data-unit (MU-PPDU) based on at least one condition. Then, the sender may transmit the MU-PPDU with the duplicated packet to at least one receiver when the condition is met.
