Abstract: An example wake-up packet sending method includes obtaining, by a sending apparatus, a wake-up packet (WUP), where the WUP includes a preamble sequence, and sending the WUP to wake up a main receiver of a receiving apparatus. The preamble sequence includes N consecutive first sequences S, where N is an integer greater than or equal to 2 (for example, [S S]), and the N consecutive first sequences S are used to indicate that a data rate used for the WUP is a first value. Or the preamble sequence includes a second sequence M, where the second sequence M is used to indicate that a data rate used for the WUP is a second value, and the second sequence M and a first sequence S are in a bit logical negation relationship.

Abstract: This application provides a full-duplex communication method and an apparatus. The method includes: when sending a first signal to a first device by using a first transmit sector, receiving, by a third device by using a first receive sector, a second signal sent by a second device. A coverage area of the third device in a receiving direction may be divided into at least one receive sector, the at least one receive sector forms one receive sector group, and the third device may receive the second signal by using the first receive sector that is in the receive sector group and that is different from the first transmit sector. In this way, the third device can simultaneously receive a signal and send a signal by using different sectors, to implement full-duplex transmission, and reduce mutual interference between signal sending and signal receiving, thereby improving communication quality of the full-duplex transmission.
