Distributed multi-user (MU) wireless communication

A method of wireless communication by a first access point of a plurality of access points, the method comprising:

• transmitting one or more group formation trigger frames;
• receiving, from one or more of the plurality of access points and after transmitting the one or more group formation trigger frame, one or more frames that indicate an intent of the one or more access points to participate in a distributed transmission, the distributed transmission being associated with each of the first access point and the one or more access points;
• transmitting, to the one or more access points, a sounding announcement frame, wherein the sounding announcement frame includes an identification of the one or more access points;
• transmitting a sounding packet after transmitting the sounding announcement frame;
• receiving, after transmitting the sounding packet, channel feedback information from one or more user terminals;
• and
• transmitting a transmission associated with the distributed transmission via beamforming, wherein the beamforming is based on the channel feedback information.

A first access point of a plurality of access points, comprising:

• at least one transceiver;
• at least one memory storing computer executable code;
• and
• one or more processors coupled to the at least one memory and configured to, individually or collectively, execute the computer executable code to cause the first access point to:
• transmit, via the at least one transceiver, one or more group formation trigger frames;
• receive, via the at least one transceiver, from one or more of the plurality of access points and after transmitting the one or more group formation trigger frame, one or more frames that indicate an intent of the one or more access points to participate in a distributed transmission, the distributed transmission being associated with each of the first access point and the one or more access points;
• transmit, via the at least one transceiver, to the one or more access points, a sounding announcement frame, wherein the sounding announcement frame includes an identification of the one or more access points;
• transmit, via the at least one transceiver, a sounding packet after transmitting the sounding announcement frame;
• receive, via the at least one transceiver, after transmitting the sounding packet, channel feedback information from one or more user terminals;
• and
• transmit, via the at least one transceiver, a transmission associated with the distributed transmission via beamforming, wherein the beamforming is based on the channel feedback information.
