Abstract: Logic may comprise hardware and/or code to select a narrow band from a wider channel bandwidth. Logic of communications between devices may select, e.g., a 1 or 2 MHz sub-channel from a wider channel bandwidth such as 4, 8, and 16 MHz and transmit packets on the selected 1 or 2 MHz channel. For instance, a first device may comprise an access point and a second device may comprise a station such as a low power sensor or a meter that may, e.g., operate on battery power. Logic of the devices may facilitate a frequency selective transmission scheme. Logic of the access point may transmit sounding packets or control frames across the sub-channels of the wide bandwidth channel, facilitating selection by the stations of a sub-channel and subsequent communications on the sub-channel between the access point and the station.

Abstract: Examples of a communication device and methods for synched distributed advertisement for device-to-device are generally described herein. In some embodiments, a method can include transmitting, from a first device of a publishing group, at a group publishing beacon interval (T), a first publishing beacon (PB) including social information of the first device and social information of (N?1) other devices, wherein the group publishing beacon interval (T) represents a preset interval of time between each successive publishing beacon transmission of the publishing group, and wherein the first publishing beacon and the each successive publishing beacon includes a first value representative of the group publishing beacon interval.

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.

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: Methods and systems for communicating in a wireless network may distinguish different types of packet structures by modifying the phase of a modulation constellation, such as a binary phase shift keying (BPSK) constellation, in a signal field. Receiving devices may identify the type of packet structure associated with a transmission or whether the signal field is present by the phase of the modulation constellation used for mapping for the signal field. In one embodiment, the phase of the modulation constellation may be determined by examining the energy of the I and Q components after Fast Fourier Transform. Various specific embodiments and variations are also disclosed.

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: Briefly, in accordance with one embodiment of the invention, an access point may provide multiple access to a single medium by providing time division multiple access to the medium. During a first phase to communicate with devices of a first type, the access point may transmit a beacon to indicate to devices of a second type not to communicate during the first phase. During a second phase to communicate with devices of the second type, the access point may transmit a beacon to indicate to devices of the first type not to communicate during the second phase. In one particular embodiment, the access point may transmit a medium reservation packet to indicate reservation of the medium for affected devices. Phases may be adaptively extended by transmitting additional medium reservation packets until it is desired to end the present phase and transition to the second phase.

Abstract: Examples are disclosed for a reverse direction grant (RDG) on a wireless communication channel between a first wireless device and a second wireless device. In some examples, an RDG may be used by the second wireless device to transmit data over a communication channel for a wireless local area network (WLAN) reserved for use by the first wireless device during a transmit opportunity (TxOP) time period. For these examples, the second wireless device may acknowledge the RDG but may wait for expected data to arrive before transmitting data over the communication channel. Other examples are described and claimed.

Abstract: An approach is provided for managing a wireless network access point beacon. The approach involves determining to one or more of (1) cause, at least in part, a beacon pointer associated with a beacon of a wireless network access point to be transmitted and (2) cause, at least in part, a beacon schedule associated with the beacon of the wireless network access point to be adjusted based, at least in part, on a derivation of one or more other beacon schedules associated with one or more other beacons of one or more other wireless network access points. The determination to cause the adjustment of the beacon schedule is based, at least in part, on a received indication of a potential conflict between the beacon and the one or more other beacons.

Abstract: A method for transmit time offset in a UL-MU-MIMO system monitors respective transmit powers, over a wireless channel, for a plurality of stations in the system. A respective transmit time offset is determined for each station in response to the respective transmit power of each station. A poll exchange sequence is initiated in which the transmit time offsets are transmitted to each respective station. An access point can then receive data from the stations at times adjusted by the respective transmit time offsets.

Abstract: Logic for collision mitigation between transmissions of wireless transmitters and receivers operating at different bandwidths. Logic of the receivers may be capable of receiving and detecting signals transmitted at narrower bandwidths. In several embodiments, the receivers comprise a clear channel assessment logic that implements a guard interval (or cyclic prefix) detector to detect transmissions at narrower bandwidths. For instance, a two MegaHertz (MHz) bandwidth receiver may implement a guard interval detector to detect 1 MHz bandwidth signals and a 16 MHz bandwidth receiver may implement logic to detect one or more 1 MHz bandwidth signals and any other combination of, e.g., 1, 2, 4, 8 MHz bandwidth signals. In many embodiments, the guard interval detector may be implemented to detect guard intervals on a channel designated as a primary channel as well as on one or more non-primary channels.
