本申请案实施例提供了一种通信方法和设备，所述方法包括：接收端按照默认检测周期打开检测窗口；若所述接收端在连续的默认个数的检测窗口内都检测到无线框的前导码，则所述接收端切换到唤醒状态；所述接收端在所述唤醒状态接收所述无线框。在本申请案实施例中，接收端只有在连续的检测窗口检测到前导码，才会切换到唤醒状态。可以使得接收端只有在检测到长前导码时，才会切换到唤醒状态；在检测到标准前导码时，则不会切换到唤醒状态。通过连续检测机制，从而降低接收端被误唤醒的概率。

The embodiments of the present application provide a communication method and apparatus. The method comprises: a receiving end opening detection windows according to a pre-set detection period; if a preamble of a radio frame is detected, by the receiving end, in each of the pre-set number of continuous detection windows, the receiving end switching to a wakeup state; and the receiving end receiving, in the wakeup state, the radio frame. According to the embodiments of the present application, the receiving end switches to the wakeup state only when the preamble is detected in the continuous detection windows. The receiving end may be configured to switch to the wakeup state only when a long preamble is detected, and to not to switch to the wakeup state when a standard preamble is detected. By means of a continuous detection mechanism, the probability of the receiving end being mistakenly woken up is reduced.
