1. A wireless initiator access point, comprising:
a communication interface with an array of antennas, wherein the communication interface is configured to:
operate the array of antennas with a precoding configuration for multi-user multiple-input multiple-output (MU-MIMO) communication with a plurality of wireless stations;
send a null data packet (NDP) announcement frame to the wireless stations and to a wireless participator access point (PAP) for triggering the wireless PAP to send an NDP frame to the wireless stations;
receive a plurality of compressed beamforming frames from the wireless stations; and
forward the compressed beamforming frames to the wireless PAP.
