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.
