    Abstract: A wireless device, system and method. The device includes a processing circuitry is configured to decode duplicate Request to Send (RTS) frames from a first access point (AP) that is part of an Extended Service Set (ESS) including a second AP, the first AP and the second AP buffering data for the device. The processing circuitry is further to cause transmission of duplicate multi-AP channel bonding (MACB) Trigger frames to the first AP and to the second AP in response to the duplicate RTS frames. Each of the duplicate RTS frames and duplicate Trigger frames have a legacy preamble portion over a first bandwidth of a corresponding wireless channel, and a MACB portion over a second narrower bandwidth of the corresponding wireless channel. The processing circuitry is further to decode a first data frame portion from the first AP and a second data frame portion from the second AP.

    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: 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.

    Abstract translation: 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中继的设备的功率消耗。 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。

    Abstract: Embodiments allow a wireless device configured to work with the 802.11n/ac standard to work in the communication bands where 802.11p devices operate with little change. Embodiments may receive signals using a receiver adapted for the wider bandwidth 802.11n/ac signals. Embodiments may also increase the sensitivity of the receiver to reduce the likelihood of missing the presence of a lower bandwidth 802.11p signal. When a signal is detected, embodiments may process the incoming signal as if it were an 802.11n/ac signal while also processing incoming signal samples in a way that effectively narrows the receiver bandwidth to identify whether an 802.11p signal is present. If the device detects the presence of an 802.11n/ac signal, it may terminate the 802.11p signal processing and proceed with normal 802.11n/ac operation. If the device detects the presence of an 802.11p signal, it may terminate 802.11n/ac processing and trigger collision avoidance processes.
