Methods and systems operating 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 include an open loop power control index 1 and a power adjustment index 2. The one or more STAs may estimate a path loss to set a baseline power using the indicated AP transmit power and receive power. The one or more STAs may adjust their transmit power to the target receive power indicated at the AP in the UL transmission period. 提供了在WLAN中操作的方法和系统。公开了用于发射功率控制(TPC)方案的方法和系统。在一实施方式中，接入点(AP)可以发送触发帧至一个或多个站(STA)用于同步和调度上行链路(UL)多用户(MU)传输。该触发帧可以包含开环功率控制索引1和功率调整索引2。一个或多个STA可以使用指示的AP发射功率和接收功率估计路径损失以设置基线功率。一个或多个STA可以在UL传输周期中调整它们的发射功率为AP处指示的目标接收功率。
