Title:
PROTOCOL AND FRAME FORMAT FOR COORDINATED BEAMFORMING
Document Type and Number:
WIPO Patent Application WO/2023/046179
Kind Code:
A1
Abstract:
The present disclosure provides methods and apparatus for coordinated beamforming. An aspect of the disclosure provides a method. The method includes sending, by a first access point (AP) of a plurality of collaborating APs, to one or more stations (STAs) associated with the plurality of collaborating APs, a request for channel state information (CSI) associated with the one or more STAs and the first AP. The method further includes receiving a response including the CSI associated with the one or more STAs and the first AP. The method further includes sending, to a second AP of the plurality of collaborating APs, a sounding request indicating the second AP to request, from the one or more STAs, CSI associated with the one or more STAs and the second AP. The method further includes sharing CSI information between the first and the second AP.
