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: This application provides a communications method and a communications apparatus. A first station in a first multi-link device sends first information to a second multi-link device, where the first information is used to indicate a frequency at which how often a station in a power saving mode in the first multi-link device receives a beacon frame. In this way, the second multi-link device may learn about, based on the first information, how often a frequency at which a station in the first multi-link device receives a beacon frame, thereby helping the second multi-link device effectively manage a cache service of each station in the first multi-link device and manage a data buffer space.

Abstract: A method for selecting a cyclic shift diversity sequence, and a related apparatus are disclosed. The method includes: sending a frame by using a cyclic shift diversity (CSD) sequence, comprising: generating a frame, wherein the frame comprises a first data subframe conforming to a first communication mechanism and a third data subframe conforming to the first communication mechanism; sending the frame, wherein the first data subframe and the third data subframe are sent by using a cyclic shift diversity sequence. Under an EHT standard, a preferred cyclic shift diversity sequence can be obtained through selection from massive combinations of CSD values. Work efficiency is improved, and an operation burden is reduced.
