    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 of a user station (STA) and methods for WLAN channel selection through beacon requests are generally described herein. In some embodiments, a STA requests that an access point (AP) transmit a beacon signal on a first sub-band. The first sub-band may include a channel of interest to the STA. The STA may determine that the AP supports the first sub-band if the AP transmits the requested beacon signal.

    Abstract: A wireless device may include processing circuitry that is configured to process a preamble of a packet, the preamble comprising a legacy portion comprising a legacy signal field (L-SIG) and a subsequent portion comprising a non-legacy signal field. The processing circuitry may be further configured to determine whether a symbol of the non-legacy signal field is modulated using binary phase shift keying (BPSK) or modulated using quadrature binary phase shift keying (OBPSK). The processing circuitry may be further configured to process the subsequent portion of the packet in accordance with a first packet format if the symbol of the non-legacy signal field is modulated using OBPSK, and to process the subsequent portion of the packet in accordance with a different packet format if the symbol of the non-legacy signal field is modulated using BPSK.

    Abstract: Navigation systems for use in indoor environments may include a navigation system that can calculate a time of flight of signals between a navigation device and a WiFi® Access Point. Such a calculation can be more accurate not just by using more accurate oscillators in devices, but by correcting a relative error between two devices. This relative error may be found by determining a timing offset correction, a difference in accuracy between the navigation device and the WiFi® Access Point. This may be performed by performing a fine frequency estimation on a long training field or by receiving a parts per million (ppm) offset from another device. Once the ppm offset is determined, the accuracy of the navigation device can be improved by a factor of 50 using a series of equations described in the disclosure.

    Abstract: Generally discussed herein are systems and apparatuses arranged to perform a Time-of-Flight (ToF) or Round Trip Time measurement. The disclosure also includes techniques of making and using the systems and apparatuses. According to an example a station (STA) can be arranged to perform a Time-of-Flight (ToF) measurement, the STA can include a transceiver arranged to transmit a hard constraint indicating a time window in which the STA is unavailable for performing the ToF measurement, and receive an action frame of the ToF measurement from another STA at a time that is outside the time window.

    Abstract: Embodiments of a wireless station to operate as a per-symbol relay device and method for retransmission of symbols between client devices and a master device using millimeter-wave links is generally disclosed herein. In some embodiments, the relay device may receive one or more of independent symbol streams from the master device. Each independent symbol stream may comprise packets that include groups of one or more symbols. Each group within a packet may be destined for a different one of the client devices. The relay device may separately decode each symbol or group of symbols to generate an independent stream of symbols for retransmission to the client devices using beamforming. The relay device may be arranged to receive, decode, and retransmit each symbol or group of symbols within a delay that is bounded by the number of symbols in the group.
