Abstract: Two methods for energy-efficient idle listening enhancement for WLAN systems are provided. The first method performs a change of operation of a station (STA) from an active mode to an idle listening mode without notifying the change to an access point (AP) associated with the STA. In the idle listening mode, the AP may transmit frames to the STA using a higher bandwidth, but the STA can only sense channels in a lower bandwidth to save energy. The second method transmits a frame to the AP associated with the STA to notify the AP the change of operation of the STA from the active mode to the idle listening mode. In the idle listening mode, the AP may transmit frames to the STA using the lower bandwidth, and the STA can only sense channels in the lower bandwidth to save energy.

Abstract: Disclosed are methods and systems for tailoring the transmit power of a wireless device to the parameters of the device such as the process split, voltage, and temperature. The device may identify one or more parameters of the device such as identifying the process split, or sensing the operating voltage or temperature.

The updated transmit power is determined to be a maximum transmit power that meets one or more target transmit metrics, such as EVM and spectral mask, when the device transmits based on the known parameter values and across a range of variations of the unknown parameter values. The device may adjust its transmit power based on the updated transmit power periodically.
