Abstract: A method and apparatus are disclosed for transmitting battery status information within a Wi-Fi beacon from an access point. In some embodiments, a battery charge information element comprising battery status information may be included within a Wi-Fi beacon. In some other embodiments, the battery charge information element may be transmitted as part of a probe and response protocol. A station, in response to receiving the battery charge information element, may display a message to the user, search for another Wi-Fi network, or search for another network through a different network interface.

Abstract: Systems and methods are provided for coordinating power management for wireless communications devices in an independent basic service set (IBSS). An announcement traffic indication message (ATIM) coordinator receives address information for destination stations for which data is buffered for transmission at source stations. The ATIM coordinator sends an ATIM Indication frame at the end of an ATIM window, alerting any destination station to remain awake to receive buffered data. Source stations may enter power save mode during the ATIM window after transmitting the address information for the destination stations to the ATIM coordinator. Destination stations may enter power save mode after receiving a beacon at the start of the ATIM window. Source and destination stations may awaken at the end of the ATIM window to receive the ATIM Indication frame.

Abstract: Systems and methods are provided for coordinating power management states in a wireless communications device. An access point may buffer data for a station and may then initiate transfer of the buffered data to the station when the station is considered to be in active mode. The access point may transmit each of the one stored data frames with a more data indication when at least one additional frame is buffered and with a no more data indication when no additional frames are buffered. Receipt of the terminal frame including the no more data indication allows the station to return to power save mode without waiting for any timeout period and without risking missing a transmission from the access point.

Abstract: Access to an access point is restricted to a plurality of client devices having wireless connections with the access point. The wireless connections conform to a wireless networking protocol. A first data transmission rate is the lowest data transmission rate defined by the wireless networking protocol. It is determined that a second data transmission rate is used between a first client device of the plurality of client devices and the access point. The second data transmission rate is the lowest data transmission rate used by the plurality of client devices. The second data transmission rate is greater than the first data transmission rate. Responsive to said determining that the second data transmission rate is the lowest data transmission rate used by the plurality of client devices, a beacon frame data transmission rate is set to the second data transmission rate.

Abstract: The present disclosure provides techniques for rate adaptation under congestion and latency constraints. The approaches described herein focus on aspects of latency, reliability, and power consumption instead of the traditional aspect of throughput. In an example, a method for rate adaptation is disclosed. The method may include determining whether to transmit a new packet or a retry packet. The method may also include reducing a maximum rate for a rate search in response to determining to transmit the retry packet. The method may further include transmitting the retry packet based on the reduced maximum rate.
