摘要： 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.

摘要： Embodiments of device-to-device (D2D) discovery, authentication, and connection techniques are generally described herein. In an example, a device-to-device connection establishment technique may be performed directly between peer-to-peer wireless communication devices without obtaining authentication information from a cloud network or an external service. The device-to-device connection establishment technique may include a transmission of a discovery request to available devices, a transmission of a response from available devices including authentication data, and a verification of the authentication data. The authentication data may include previously stored image data associated with a device or human user associated with a device. In further examples, image processing and image recognition techniques may be used to verify a particular device or human user associated with a device.

摘要： 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 16M Hz 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.

摘要： 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.

摘要： Logic may implement an orthogonal frequency division multiplexing (OFDM) system operating in the one gigahertz and lower frequency bands. Logic may detect new long training sequences that are differentially orthogonal to each other for a first bandwidth mode of operation such as a one megahertz mode as well as differentially orthogonal to half of the long training sequence for a second bandwidth mode of operation such as a two megahertz or greater mode. Logic may implement two or more long training sequences for the first bandwidth mode of operation to transmit information based upon the selection of the particular long training sequence for the transmission. Logic may implement a new acknowledgement packet comprising a short training sequence and a long training sequence without a signal field and without a payload. And logic may implement bandwidth detection logic to classify a transmission based upon orthogonal properties of the long training sequences.

摘要： Devices and methods of providing communications between a Low-Power (LP) STA and an Assisting STA are generally described. Different TXOPs are used for communication with the LP STA with an AP. A wideband preamble is transmitted on a 20 MHz channel and a narrowband trigger frame on a 2 MHz subchannel of the channel. A narrowband response is transmitted from the LP STA to the Assisting STA in response to transmission of the trigger frame. The response contains predetermined duration of data and an address of the Assisting STA and/or AP. The response potentially has a transmission range less than a distance from the LP STA to the AP. A narrowband ACK is transmitted in response to reception of the response. The trigger frame, the response and the ACK use the same subchannel. After reception of the response, a wideband communication containing the data is transmitted from the Assisting STA to the AP.

In some examples, an apparatus for dynamically setting a clear channel assessment (CCA) threshold in a wireless local area network (WLAN) may comprise a processor component, a radio coupled to the processor component, and logic for execution by the processor component to establish a CCA threshold for a wireless channel of the WLAN, send a first wireless message to one or more wireless station (STA) devices in wireless proximity to the apparatus informing the one or more STA devices of the established CCA threshold and instructing the one or more STA devices to avoid CCA levels exceeding the CCA threshold on the wireless channel and send a second wireless message to a wireless access point (AP) device associated with the apparatus informing the AP device of the established CCA threshold and instructing the AP device to broadcast use of the CCA threshold on the wireless channel. Other examples are described and claimed.

摘要： Logic such as hardware and/or code to narrow available sub-channels in frequency selective transmission communications in which a station selects a narrow band from a wider channel bandwidth. A frequency selective transmission scheme for communications devices may select a 1 or 2 MHz channel from a wider channel bandwidth (e.g., 4, 8, 16 MHz) that consists of a number of 1 or 2 MHz sub-channels and transmitting packets on the selected sub-channel. The access point may narrow the number of sub-channels available for selection by stations. Stations may narrow the number of sub-channels. Both the AP and the stations may operate to narrow the number of sub-channels. A medium access control sub-layer protocol common to the communications devices may facilitate a frequency selective transmission scheme.

摘要： Some new low power architecture devices may, e.g., be associated with in a new device category in the IEEE 802.11ah Standard for devices with low power architecture. Some new low power architecture devices may only to support a subset of modulation and coding schemes (MCSs). Some new low power architecture devices negotiate the use of the subset of MCSs with an access point. Further new low power architecture devices address power consumption through modifications to the architecture of the new low power device. For instance, many new low power architecture devices remove, modify or bypass portions of the front-end transmitter circuitry and/or the front-end receiver circuitry such as a power amplifier, a low noise amplifier, predistortion circuitry, digital-to-analog and analog-to-digital converter resolutions, and stages of filtering.
