Patent number: 11690015Abstract: 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.Type: GrantFiled: March 26, 2021Date of Patent: June 27, 2023Assignee: QUALCOMM IncorporatedInventors: Soumen Chakraborty, Shwetank Kishorkumar Mistry, Kyungwan Nam, Ming-Tuo Chin, James Michael Gardner, Arvind Keerti, Chiao Cheng Huang
