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: 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.
