1. A method, comprising:
receiving, by an apparatus implemented in a master access point (AP), a report on received power levels, a respective spatial reuse parameter (SRP), and a receiver sensitivity of each of one or more coordinated APs from each of one or more stations (STAs) associated with the master AP;
selecting, by the apparatus, a coordinated AP from the one or more coordinated APs; and
performing, by the apparatus, coordinated spatial reuse (CSR) transmissions in conjunction with the at least one coordinated AP,
wherein the selecting of the coordinated AP comprises selecting the coordinate AP due to:
at least one STA of the one or more STAs associated with the master AP observing low interference from the coordinated AP; and
the master AP causing low interference on a coordinated basic service set (BSS) associated with the coordinated AP.
