1. A method of configuring a wireless access point for cooperative transmission in a wireless network, the method comprising:
a first wireless AP determining transmit power information for transmitting data in cooperation with a second wireless AP based on RSSI measured by the first wireless AP and the second wireless AP; and
the first wireless AP transmitting a coordinated spatial reuse announcement frame comprising the transmit power information to the second wireless AP, wherein the announcement frame comprises a maximum transmit power, wherein the second wireless AP is operable to transmit data on a wireless channel according to the transmit power information, and wherein the second wireless AP transmits data using a transmit power that is equal to or less than the maximum transmit power indicated in the announcement frame.
