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: Example methods for indicating downlink service data and devices are described. One example method includes controlling, by a first station (STA) associated with a radio access point (AP), a wake-up receiver of the first STA to wake up within a preset first listen interval. The first STA receives a wake-up beacon frame sent by the AP, and controls main radio (MR) of the first STA not to wake up within a second listen interval to receive a beacon frame sent by the AP. According to the method provided in this application, the MR of the first STA does not need to wake up within the second listen interval to receive the beacon frame broadcast by the AP.

Abstract: In a method of sending a frame using a cyclic shift diversity (CSD) sequence, a wireless device generates a frame comprising a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal (L-SIG) field, a repeated legacy signal (RL-SIG) field, an extremely high throughput signal A (EHT-SIG A) field, and an extremely high throughput signal B (EHT-SIG B) field. The wire device sends the frame through a set of transmit antennas by performing cyclic shift over the fields according to a CSD sequence. The number of transmit antennas is greater than 8. The number of cyclic shift diversities in the CSD sequence is equal to a number of the transmit antennas, and each cyclic shift diversity has a value that is a multiple of 12.5.
