Abstract:
Methods and systems for operation in a WLAN are provided. Methods and systems for a transmit power control (TPC) scheme are disclosed. In an embodiment, an access point (AP) may send a trigger frame to one or more stations (STAs) for synchronizing and scheduling uplink (UL) multi-user (MU) transmissions. The trigger frame may contain an open-loop power control index 1 and a power adjustment index 2. The one or more STAs may estimate pathloss using an indicated AP transmit power and received power to set a baseline transmit power. The one or more STAs may adjust their transmit power in the UL transmission period to be the indicated target receive power at the AP.

Claim (Index 9):
A station (STA) comprising:\n at least one receive circuit configured to receive a trigger frame broadcast to a plurality of STAs, the trigger frame indicating one or more building blocks in an upcoming uplink (UL) multi-user (MU) transmission opportunity are available to one or more STAs in the plurality of STAs for data transmissions; the at least one receive circuit further configured to receive power control information in the trigger frame, the power control information comprising a transmit power that an access point (AP) used to transmit the trigger frame and a target receive signal power at the AP; the at least one receive circuit further configured to measure a received power of the trigger frame; at least one processor configured to calculate a downlink pathloss of the trigger frame based on the received transmit power of the trigger frame and the measured received power of the trigger frame; the at least one processor further configured to determine a baseline transmit power based on the downlink pathloss and the target receive signal power at the AP; and at least one transmit circuit configured to send a data transmission in the one or more building blocks using the baseline transmit power.
