Abstract:
IEEE 802.11 power saving mode (PSM) defines two different power modes under which stations operate: active mode and power save (PS) mode. This disclosure introduces devices, methods, and systems to implement an additional power save with ultra low power (PS-ULP) mode that further reduces power consumption. In one aspect, a method of communicating a power management mode of a station on a wireless network is disclosed. The method includes transmitting by a station a first message on the wireless network, the first message indicating one of at least three power management modes, wherein the indication is communicated in a power management portion of a frame control field of a media access control header. The power management portion comprises more than one bit; and operating the station in a power management state in accordance with the indicated power management mode.
