Abstract: A host assembly of a wireless device enters into a handshaking procedure with firmware of the wireless device to initiate entry into or exit from a host sleep mode. Before such entry or exit, the handshaking procedure may require the host assembly to send an initiation handshake signal to the firmware, and require the firmware to send a confirmation handshake signal back to the host assembly. Entry or exit may be delayed until after the confirmation signal is received. The confirmation signal may vary depending on the handshaking configuration and activation data, and the confirmation signal may vary depending on whether the wireless device is in a power save mode or not.

Abstract: This disclosure describes techniques and apparatuses for wakeup beacons for mesh networks, which often permits nodes of a mesh network to save power when operating in a power-save mode. These wakeup beacons can be sent at high transmission rates and/or be small in size, thereby reducing the time a node must be awake to transmit and receive communications.

Abstract: Secure block acknowledgment techniques for use in communication networks are discussed. In one embodiment, a method includes setting up a session with a transmitting station in which the transmitting station is to perform a block acknowledgment to confirm receipt of packets, the session including determining whether the transmitting station has a capability to implement a mechanism to securely perform a block acknowledgement. The embodiment includes receiving an information unit including information indicative of a request for the communication device to adjust a receiving window associated with the session, determining whether the received information unit is in accordance with the mechanism, adjusting the receiving window if the received information unit is in accordance with the mechanism, and not adjusting the receiving window if (i) the received information unit is not in accordance with the mechanism, and (ii) the transmitting station is determined to have the capability to implement the mechanism.
