Abstract: A data transmission indication method and apparatuses carrying out the method are described herein. The method includes sending, by an access point, orthogonal frequency division multiple access (OFDMA) physical layer signaling to a terminal. The OFDMA physical layer signaling indicates, to the terminal, a subchannel allocated for the terminal, so that the terminal determines the subchannel according to the OFDMA physical layer signaling. The OFDMA physical layer signaling includes an identifier of the terminal and subchannel information corresponding to the identifier of the terminal. A manner in which the access point allocates a subchannel for each terminal according to OFDMA physical layer signaling enables the access point to indicate subchannels for more terminals.

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.
