1. A method comprising:
sending a trigger frame to a client;
receiving an uplink transmission from the client;
determining a client Transmission (TX) power and a Received Signal Strength Indication (RSSI) associated with the client using the uplink transmission;
determining a client location;
determining a pathloss associated with the client using the client location and the uplink transmission;
determining a directional gain using the client TX power, the pathloss, and the RSSI;
determining an array gain based on the directional gain,
wherein determining the array gain comprises determining a spherical Three Dimensional Multi-User Multiple-Input Multiple-Output Composite Directional Gain (3D-MU-MIMO-CDG); and
adjusting an Access Point (AP) TX power based on the array gain.
