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.

Abstract: Aspects relate to outputting a training field signal and/or obtaining a training field signal over multiple radio frequency (RF) sub-bands. For example, a carrier bandwidth used by a first apparatus to transmit packets may include several RF sub-bands. The first apparatus may use two or more of these RF sub-bands to transmit a training field signal. In some examples, the first apparatus may repeat the same training field signal over multiple RF sub-bands. In some examples, the second apparatus may combine the training field signal sent over the multiple RF sub-bands.
