Abstract: This disclosure provides methods, components, devices and systems for interference reduction between wireless communication devices of overlapping basic service sets (OBSSs). Some aspects more specifically relate to signaling mechanisms associated with an OBSS channel sounding operation and power control mechanisms associated with OBSS interference mitigation, either or both of which a first access point (AP) associated with a first basic service set (BSS) may leverage as part of a coordinated beamforming scheme with a second AP associated with a second BSS. In accordance with OBSS channel sounding, the first AP may associate a set of sounding packets with one or more parameters indicative of the second BSS such that the sounding packets appear, to OBSS stations (STAs), as in-BSS sounding packets. Additionally, or alternatively, the first AP may employ a power control mechanism according to which the first AP may apply portion-by-portion transmission power control.
