Abstract: This application provides a physical layer convergence procedure protocol data unit communication method and a related apparatus. The method includes: receiving, by a receiving apparatus, a physical layer convergence procedure protocol data unit PPDU sent by a sending apparatus, where the PPDU includes synchronization adjustment indication information and a data field, and the synchronization adjustment indication information and the data field are sent in a bandwidth less than 20 MHz; and performing, by the receiving apparatus, time synchronization and automatic gain control AGC on the data field based on the synchronization adjustment indication information. According to this solution, the receiving apparatus can perform, by using the synchronization adjustment indication information, time synchronization and automatic gain control AGC on the PPDU transmitted in a narrow bandwidth.

Abstract: This application relates to the wireless communications field and provides a frame transmission method, device, and system. The method includes: sending, by a second device, n wake-up frames to a first device, where the n wake-up frames each carry segmented content of wake-up signaling, so that a wake-up receiver of the first device wakes up a main transceiver of the first device based on the n wake-up frames, and after being woken up, the main transceiver sends, to the second device, a response frame used to indicate whether the n wake-up frames are correctly received. In this application, content of the wake-up signaling is segmented. In this case, lengths of the n wake-up frames are all relatively short, so that the wake-up receiver is easier to correctly receive each wake-up frame.
