    • 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.
    • 本文通常描述设备到设备(D2D)发现,认证和连接技术的实施例。 在一个示例中,可以在对等无线通信设备之间直接执行设备到设备连接建立技术,而不从云网络或外部服务获取认证信息。 设备到设备连接建立技术可以包括向可用设备发送发现请求,从包括认证数据的可用设备的响应的传输和认证数据的验证。 认证数据可以包括与与设备相关联的设备或人类用户相关联的先前存储的图像数据。 在另外的示例中,可以使用图像处理和图像识别技术来验证与设备相关联的特定设备或人类用户。

    • Embodiments may comprise logic such as hardware and/or code to reduce power consumption by, e.g., a device such as a station or relay by implementing prediction logic to decode and determine whether a communication affects the operation of the device. Some embodiments may comprise logic to receive at least a portion of a header of a frame from a physical layer and begin to decode the portion of the header of the frame without first checking the correctness of the value in the frame check sequence field. In many embodiments, prediction logic may determine whether the frame could have an impact on the operation of the device. For circumstances in which the prediction logic determines that the frame will not have an impact, the MAC logic may terminate processing, receipt, and decoding of the frame and enter the device into a low power consumption state.
    • 实施例可以包括诸如硬件和/或代码的逻辑,以通过实现预测逻辑来解码并确定通信是否影响设备的操作来减少例如诸如站或继电器的设备的功率消耗。 一些实施例可以包括用于从物理层接收帧的头部的至少一部分的逻辑,并且开始对帧的头部的部分进行解码,而不首先检查帧校验序列字段中的值的正确性。 在许多实施例中,预测逻辑可以确定帧是否可能对设备的操作产生影响。 对于预测逻辑确定帧不会产生影响的情况,MAC逻辑可以终止帧的处理,接收和解码,并将该设备进入低功耗状态。

    • 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.
    • 逻辑可以包括从更宽的信道带宽中选择窄带的硬件和/或代码。 设备之间的通信逻辑可以从诸如4,8和16MHz的更宽的信道带宽中选择例如1或2MHz的子信道,并在选择的1或2MHz信道上发送分组。 例如,第一设备可以包括接入点,并且第二设备可以包括诸如低功率传感器或可以例如对电池电力进行操作的仪表的站。 设备的逻辑可以促进频率选择性传输方案。 接入点的逻辑可以在宽带宽信道的子信道上发送探测分组或控制帧,便于站点选择子信道,并在接入点和站之间的子信道上进行随后的通信。
