    • Techniques are disclosed that involve communicating in bursty noise environments. For instance, a source device may send a probing packet to a destination device. This probing packet is for determining whether the communications medium (e.g., one or more frequency channels) is currently exhibiting a busy or jammed (e.g., due to bursty noise) condition. More particularly, based on whether an acknowledgment of the probing packet is received, the source device determines whether the channel is jammed (or busy) or clear. For example, an unacknowledged probing packet indicates that the channel is jammed or busy, while an acknowledged probing packet indicates that the channel is clear. If the channel is determined to be clear, then the source device may transmit one or more data packets to the destination device. Such data packet transmissions may be in accordance with a non rate-adaptive technique.
    • 公开了涉及在突发噪声环境中进行通信的技术。 例如,源设备可以向目的地设备发送探测分组。 该探测分组用于确定通信介质(例如,一个或多个频率信道)当前是否正在呈现忙或卡住(例如,由于突发噪声)条件。 更具体地,基于是否接收到探测分组的确认,源设备确定信道是否被卡住(或忙)或清除。 例如,未确认的探测分组指示信道被卡住或占线,而确认的探测分组指示信道是清除的。 如果信道被确定为清除,则源设备可以向目的设备发送一个或多个数据分组。 这样的数据分组传输可以是根据非速率自适应技术。
