18 Claims

11. An apparatus for wireless communication, comprising: a memory comprising instructions; and at least one processor and configured to execute the instructions and cause the apparatus to: provide power control parameters associated with the apparatus for transmission to an access point; obtain a frame received from the access point, the frame including a downlink transmit power used to transmit the frame and further including uplink power control information being based on the power control parameters, the uplink power control information comprising a target receiver power level for at least one of uplink multiuser multiple-input-multiple-output (ULMU-MIMO) transmission or uplink orthogonal frequency-division multiple access (UL OFDMA) transmission to be received at the access point; determine a transmit power based on the received uplink power control information including the target receiver power level; and provide a second frame for transmission to the access point based on the determined transmit power; wherein the apparatus determines the transmit power by: determining a pathloss with the access point based on a downlink transmit power indicated in the frame; and computing the transmit power based on the determined pathloss and the uplink power control information.
