    • Disclosed are methods, systems, devices, and computer readable storage medium to manage a received signal strength of sounding frames at a receiving device. If the received signal strengths vary, an automatic gain control parameter may be more highly influenced by those frames having higher received signal strength. A trigger frame indicates a transmission power of the trigger frame, and a target received signal strength at an access point transmitting the trigger frame. Receiving stations may determine a transmit power for a sounding frame based on the trigger frame. For example, a path loss between the access point and receiving station may be determined based on the transmit power and the received power of the trigger frame. A transmit power for the sounding frame may then be determined, in some aspects, by adding the path loss and the target RSSI value.
    • 公开了用于管理接收设备处的探测帧的接收信号强度的方法,系统,设备和计算机可读存储介质。 如果接收信号强度变化,则自动增益控制参数可能受到具有较高接收信号强度的那些帧的影响更大。 触发帧指示触发帧的发送功率以及发送触发帧的接入点处的目标接收信号强度。 接收站可以基于触发帧来确定探测帧的发射功率。 例如,接入点和接收站之间的路径损耗可以基于发送功率和触发帧的接收功率来确定。 然后可以在一些方面通过添加路径损耗和目标RSSI值来确定用于探测帧的发射功率。
