Pre-sounding frames in coordinated beamforming sounding procedures

A first wireless access point (AP), comprising:

• a processing system that includes processor circuitry and memory circuitry that stores code, the processing system configured to cause the first wireless AP to:
• receive, from a second wireless AP at a start of a first transmission opportunity, a first frame that comprises an invitation for the first wireless AP to perform a coordinated beamforming sounding procedure with the second wireless AP and comprises first information associated with the coordinated beamforming sounding procedure, one or more first wireless stations (STAs) being associated with the first wireless AP participating in the coordinated beamforming sounding procedure;
• transmit, to the second wireless AP and in accordance with the first frame comprising the invitation, a second frame that indicates whether the first wireless AP accepts the invitation to perform the coordinated beamforming sounding procedure with the second wireless AP, the second frame comprising second information associated with the coordinated beamforming sounding procedure;
• and
• perform, in accordance with the first wireless AP accepting the invitation, at least a first portion of the coordinated beamforming sounding procedure with the second wireless AP in the first transmission opportunity, the coordinated beamforming sounding procedure being performed in accordance with the first information and the second information.

A method for wireless communication by a first wireless access point (AP), comprising:

• transmitting, to a second wireless AP at a start of a first transmission opportunity, a first frame that comprises an invitation for the second wireless AP to perform a coordinated beamforming sounding procedure with the first wireless AP and comprises first information associated with the coordinated beamforming sounding procedure, one or more first wireless stations (STAs) being associated with the first wireless AP participating in the coordinated beamforming sounding procedure;
• receiving, from the second wireless AP and in accordance with the first frame comprising the invitation, a second frame that indicates whether the second wireless AP accepts the invitation to perform the coordinated beamforming sounding procedure with the first wireless AP, the second frame comprising second information associated with the coordinated beamforming sounding procedure;
• and
• performing, in accordance with the second wireless AP accepting the invitation, at least a first portion of the coordinated beamforming sounding procedure with the second wireless AP in the first transmission opportunity, the coordinated beamforming sounding procedure being performed in accordance with the first information and the second information.
