Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of power management in a wireless network. For example, a first wireless station may be configured to transmit a frame to a second wireless station during a first beacon interval, the frame including an indication that the first wireless station is to switch to a low power mode; switch to the low power mode; operate at an active mode during an awake window in a second beacon interval subsequent to the first beacon interval; and upon receipt of an announcement traffic indication message (ATIM) from the second wireless station during the awake window, transmit an acknowledgement to the second wireless station, and stay at the active mode to communicate data with the second wireless station.

Abstract: Embodiments of a wireless station and method for controlling use of the 60 GHz band are described. The station (STA) can include memory and processing circuitry. The processing circuitry is configured to decode a packet received from a second STA via a microwave wireless channel. The packet includes information indicating that a millimeter wave wireless channel is unavailable for communication. A current geographic location and a mobility status for the second STA may be determined based on an authentication message originating from a third STA. The mobility status may indicate whether the second STA is moving or is stationary. The second STA may be authenticated based at least on the mobility status. Upon authenticating the second STA, usage of the millimeter wave wireless channel may be suspended for a pre-determined period of time.

Abstract: Devices and methods of limiting wideband STA communication are generally described. The STA receives, over a primary channel, a wakeup frame containing an indication of a SP or CBAP to acquire a wideband TXOP over a wide bandwidth channel including the primary channel and a secondary channel and a control trailer having an indication of the wide bandwidth channel. Prior to the SP/CBAP, the STA opens reception from the primary channel to the wide bandwidth channel. The STA then communicates with another STA over the wide bandwidth channel and subsequently reduces reception from the wide bandwidth channel to the primary channel. The wakeup frame originates from an AP/PCP or the other STA, and contains fields indicating the wakeup frame length and SP or a sensing time length prior to the CBAP.
