Abstract:
After waking from a sleep mode, a wireless communication device may poll a network controller for any broadcast and/or multicast messages. The device and the network controller may agree to this arrangement ahead of time, so that the network controller will know to buffer such messages until the device requests them. A format for enabling this capability is described.
Abstract:
Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating a wakeup packet. For example, an apparatus may include circuitry configured to cause a wireless device to generate a frame comprising a Low-Power Wakeup-Receiver (LP-WUR) capability indication to indicate a capability of the wireless device to process communication of a wakeup packet; and to transmit the frame.
Abstract:
Mobile platform power management is an important problem especially for battery-powered small form factor platforms such as smartphones, tablets, wearable devices, Internet of Things (IOT) devices, and the like. One exemplary technique disclosed herein defines a method for a fine-grained wake-up mode for Wi-Fi/BT/BLE that utilizes a low-power wake-up radio. For example, the actual data contained in the wake-up packet can be forwarded directly to a memory block of the device without waking-up the Wi-Fi/BT/BLE radio. As another example, if an IEEE 802.11 MAC frame is contained in the wake-up packet, then just the MAC processor of the Wi-Fi/BT/BLE radio can be woken up to process the IEEE 802.11 MAC frame contained in the wake-up packet, and have the PHY module of the Wi-Fi/BT/BLE radio kept powered off or in a low power mode to, for example, save energy.
Abstract:
Techniques for presenting communication by two or more stations in a WLAN environment are provided. Specifically, methods are presented, that when taken alone or together, provide a device or group of devices with an efficient way for bandwidth adaptation using echo cancellation. Even more specifically, a narrow-bandwidth transmission can be interrupted in favor of a higher-bandwidth transmission upon one or more secondary channels becoming available or going quiet.
Abstract:
Logic of an access point may transmit a null data packet for beamforming training and transmit a beamforming report poll to the first station on a user list before receiving a transmission from the first station on the user list. Logic may wait for a timeout period to determine whether the first station on the user list will respond to the null data packet prior to transmitting the beamforming report poll. Logic may receive from the first station an indication that the first station is a slow beamforming report responder. Logic may reorder the user list to position a fast beamforming responder as the first station. And logic of the station may determine that the station is unable to complete and transmit the report so the logic may wait to transmit the beamforming report in response to a subsequent beamforming report poll frame.
Abstract:
Examples are disclosed for techniques for allowing a wireless device to wake up a low power device while remaining compatible with other devices and wireless protocols. A first station determines that a low power device needs to wake up all or a portion of its circuitry in order to send and/or receive data from the first station. The first station sends a legacy preamble according to a standard wireless communication method such as according to IEEE 802.11 or Bluetooth addressed to the low power device. Legacy stations will recognize that a device is accessing the medium and will abstain from transmitting data during the transaction(s) between the first station and the low power device. The first station then sends a wake up payload according to a low power wireless communication method such as ASK or FSK to the low power device. The low power device recognizes the wake up payload and wakes up its main radio such as an IEEE 802.11 or Bluetooth radio. The first station sends and/or receives data to/from the low power device according to the standard wireless communication method. If there is no more data to send or receive, low power device powers down at least its main radio.
Abstract:
Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating a wakeup packet. For example, an apparatus may include circuitry configured to cause a first wireless device to modulate a preamble of a wakeup packet according to an Orthogonal Frequency Division Multiplexing (OFDM) scheme; modulate a payload of the wakeup packet according to an On-Off keying (OOK) modulation scheme over a plurality of OFDM tones; and transmit the wakeup packet to a second wireless device.
Abstract:
When a wireless communications device intends to communicate with another device over a wide channel consisting of multiple narrow channels, but detects interference on one or more of those narrow channels, it may restrict subsequent communications with that other device to those narrow channels that don't suffer from the interference. In one embodiment the device may simply refuse to monitor the interfering channel(s) for signals for a particular period of time. In another embodiment the device may use a CTS to signal the other device not to use the interfering narrow channel(s). That may result in using a wide channel with a reduced bandwidth for communications.
Abstract:
Some demonstrative embodiments include apparatuses, devices, systems and methods of a wakeup packet response. For example, an apparatus may include circuitry configured to cause a first wireless device to generate a wakeup packet including a wakeup response policy field to indicate a response policy; and to transmit the wakeup packet to a wakeup receiver of a second wireless device over a wakeup Resource Unit (RU) allocation of an Orthogonal Frequency Division Multiple Access (OFDMA) structure.
Abstract:
Logic for communications with an efficient acknowledgement (ACK) procedure for fragmented frames. Logic may determine an acknowledgement protocol to handle more fragments of a frame than the maximum that can be included in a bitmap of an NDP (null data packet) block acknowledgement (BlockACK). Logic may determine fragment indices to associate with an implicit ACK policy. Logic may read the Fragment Number field value in the Sequence Control field of a data frame to determine the fragment index. Logic may transmit an NDP BlockACK frame for every X fragments with fragment indices greater than X−1 so that L NDP BlockACK frames can acknowledge N fragmented frames. Logic may determine a bit number in a bitmap associated with a fragment index.
