Abstract: System and Method for Uplink Power Control in Multi-AP Coordination Embodiments compute a target power level referenced at one Access Point (AP) in accordance with path losses between two or more APs and a Station (STA). The calculated target power level is then transmitted to the STA in a downlink message, which may also include resource allocation information that indicates a location of a resource for transmitting an uplink frame. The STA may then use the target power level to calculate an uplink power level for transmitting the uplink frame over the resource location indicated by the downlink frame. In addition to the path loss values, the target power level may also be computed in accordance with measured interference levels at the APs and/or a target receive power level that is associated with, or otherwise required to decode, the uplink frame.
