Abstract: This disclosure describes systems, methods, and devices related to dynamic channel bonding and multi-band aggregation. A device may determine a plurality of aggregated medium access control (MAC) protocol data unit (A-MPDU) subframes to send to a station device including a first A-MPDU subframe and a second A-MPDU subframe. The device may determine a quiet period between the first A-MPDU subframe and the second A-MPDU subframe. The device may cause to send the plurality of A-MPDU subframes to the station device on a first channel. The device may determine a status of a second channel during the quiet period. The device may cause to send the second A-MPDU subframe to the station device using a multi-band transmission on the first channel and the second channel.

Abstract: A wireless communication device, system and method. The device includes a memory and processing circuitry coupled to the memory. The processing circuitry has a main baseband processor and a low power baseband processor, and further includes logic to cause the low-power baseband processor to process an orthogonal frequency division multiple access (OFDMA) signal allocated to a predetermined resource unit (RU) of an OFDMA packet as an OOK modulated signal including a sequence of bit values of 1 and 0. The sequence represents a low-power wake up (LP-WU) packet. The OFDMA packet has a plurality of RUs and is addressed to one or more destination OFDMA devices. The low power baseband processor is to decode an OFDMA symbol allocated to the predetermined RU as a bit value of 1, and to decode an absence of an OFDMA symbol from the predetermined RU as a bit value of 0. The logic is further to cause a wake-up of the main baseband processor based on the LP-WU packet. The main baseband processor may process subsequent OFDMA modulated data symbols as OFDMA modulated data symbols after waking up

Abstract: Embodiments may implement a new hierarchical data structure for traffic indication mapping to facilitate transmissions for wireless communications devices. Many embodiments comprise MAC sublayer logic to generate and transmit management frames such as beacon frames with a partial virtual bitmap based upon the hierarchical data structure for traffic indication mapping. In some embodiments, the MAC sublayer logic may store the traffic indication map and/or the traffic indication map structure in memory, in logic, or in another manner that facilitates transmission of the frames. Some embodiments may receive, detect, and decode communications with frames comprising the partial virtual bitmap based upon the hierarchical data structure. In some embodiments, indications of buffered data for pages, super-blocks, blocks, sub-blocks, and/or stations may be inverted. In several embodiments, a new association identifier (AID) structure is defined for the new hierarchical data structure for traffic indication mapping.

Abstract: Described herein are waveform designs and systems that enable low-power narrow bandwidth operations by battery powered Internet-of-Things devices in an 802.11ax environment. In one embodiment, a single carrier waveform is frequency multiplexed within 802.11ax OFDM transmissions in both the downlink and uplink. The single-carrier waveform provides a low peak-to-average-power-ratio to lower the overall power consumption of the battery powered devices.

Abstract: This disclosure describes systems, and methods related to signal classification in a wireless communication network. A first computing device comprising one or more processors and one or more transceiver component may receive a signal transmission packet comprising a physical layer (PHY) preamble. The first computing device may identify within the PHY preamble, one or more signal (SIG) fields, wherein at least one of the one or more SIG fields includes at least a length field indicating a length of the signal transmission packet. The first computing device may determine based at least in part on the length field, that the signal transmission packet is associated with a predetermined communication standard utilized to transmit the signal transmission packet. The first computing device may decode the signal transmission packet based at least in part on the determination that the signal transmission packet is associated with the predetermined communication standard.

Abstract: Logic may enable client devices or access points to relay medium access control (MAC) frames through a Wireless Fidelity (Wi-Fi) Direct network such as a network of Peer-to-Peer (P2P) connections to extend the wireless range of the devices or access points beyond the transmission range of the individual devices or access points. Logic may extend the range of IEEE 802.11 devices, such as IEEE 802.11ah devices, by allowing a station in the middle of two stations to serve as a relay station using the Wi-Fi Direct technology. Logic may enable relaying to avoid a full mesh technology such as is defined in IEEE 802.11s, since the full mesh technology may contain too many features that are not required for a simple or a static network configuration of such embodiments.

Abstract: Embodiments allow a wireless device configured to work with the 802.11n/ac standard to work in the communication bands where 802.11p devices operate with little change. Embodiments may receive signals using a receiver adapted for the wider bandwidth 802.11n/ac signals. Embodiments may also increase the sensitivity of the receiver to reduce the likelihood of missing the presence of a lower bandwidth 802.11p signal. When a signal is detected, embodiments may process the incoming signal as if it were an 802.11n/ac signal while also processing incoming signal samples in a way that effectively narrows the receiver bandwidth to identify whether an 802.11p signal is present. If the device detects the presence of an 802.11n/ac signal, it may terminate the 802.11p signal processing and proceed with normal 802.11n/ac operation. If the device detects the presence of an 802.11p signal, it may terminate 802.11n/ac processing and trigger collision avoidance processes.
