    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: Provided is a resistance random access memory device and a method of fabricating, the same. The method includes forming a bit-line stack in which a plurality of local bit-lines are vertically stacked on a substrate, forming a word-line including a plurality of local word-lines that extend in a vertical direction toward a side of the bit-line stack and a connection line that extends in a horizontal direction to connect the plurality of local word-lines with one another, and forming a resistance memory thin film between the bit-line stack and the word-line. The present inventive concept can realize a highly dense memory array with 3D cross-point architecture by simplified processes.

    摘要: Apparatuses, systems, and methods that reduce the amount of time for recovering multiple beam-formed links in a wireless network are disclosed. An embodiment may, e.g., be a mobile computing device with wireless beamforming communications capabilities. Upon establishing links with multiple stations, the mobile computing device may sense that the link quality or strength is degrading for several of the links. The laptop may transmit a single forward-transmission sector sweep (FWD-TXSS) to initiate recovery of the links. The other stations previously linked to the laptop may detect the degradation the links and start monitoring for the single FWD-TXSS. The receiving devices may each perform reverse-transmission sector sweeps (REV-TXSS), in sequence, to reestablish beam-formed links with the laptop without requiring multiple forward-transmission sector sweeps.

    摘要: A system and method for using spatial diversity for improving link quality, particularly wireless link communication. A plurality of propagation paths are used simultaneously for a wireless link, and a plurality of strong propagation paths are selected from among available propagation paths. Propagation path measurements are made to determine strong signal propagation paths. An array antenna at a transmitter and at a receiver are controlled to communicate over a plurality of simultaneous signal propagation paths.

    摘要: In a wireless network, information regarding the power capabilities of a wireless device may be communicated to a wireless AP. The device itself may transmit such information, which may include a Max Idle Time period. The device may communicate the information within an association or re-association frame, for example as a parameter in a BSS Low Power Capability element. The AP may receive the information and set a keep-alive time period for the device based on the information. The AP may set the keep-alive time period to be equal to or greater than the Max Idle period. The AP may further communicate the keep-alive time period to the device, for example in an association or re-association response frame as a BSS Max Idle period element. In this way, the AP may apply different sets of parameters, such as different keep-alive time periods, to different classes of stations.
