1. A method of collaborative sounding measurement in a multi-AP (MAP) wireless network, the method comprising:
receiving, by a wireless station (STA), a first announcement frame from an access point (AP), wherein the AP is a transmission opportunity (TXOP) holder operable to perform collaborative beamforming with a collaborative AP;
receiving, by the STA, a first null data packet (NDP) frame from the AP; and
calculating beamforming feedback based on the receiving the first NDP frame from the AP for performing collaborative beamforming between the AP and the collaborative AP.
