Abstract: An apparatus, including: a clock source configured to generate a local oscillator (LO) clock signal; a radio frequency digital-to-analog converter (RF DAC) configured to generate a radio frequency (RF) signal based on a data signal and the LO clock signal; and an idle data detector configured to: detect a stream of idle data in the data signal; and disable providing the LO clock signal to at least a portion of the RF DAC in response to detecting the stream of idle data.

Abstract: This disclosure provides methods, devices and systems for reducing power consumption when a station (STA) is operating in a listen mode. In some aspects, to reduce power consumption in the listen mode, the STA may alternate between monitoring a wireless channel for packets and not monitoring the wireless channel. When the STA is monitoring the wireless channel for packets in the listen mode, the STA may configure packet detection components to a power-on state. When the STA is not monitoring the wireless channel in the listen mode, the STA may configure packet detection components to a power-off state. During the power-on state of the listen mode, the STA may detect a preamble of a packet that was transmitted over the wireless channel. In response to detecting the preamble of the packet, the STA may switch from the listen mode to a receive mode to process the packet.
