Abstract: APPDU-based communication method and apparatus are disclosed, are used in a wireless local area network system that supports 802.11 series protocols such as a next-generation Wi-Fi protocol of IEEE 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and a next-generation protocol of 802.11be, for example, Wi-Fi 8. A transmit end generates a PPDU, and sends the PPDU on a first high frequency channel. Correspondingly, a receive end receives the PPDU on the first high frequency channel, and processes the PPDU. The first high frequency channel may include a first pilot subcarrier and a first data subcarrier, a quantity of first pilot subcarriers is greater than a quantity of second pilot subcarriers, and a quantity of first data subcarriers is equal to a quantity of second data subcarriers. This can effectively improve demodulation accuracy of the receive end.

Abstract: This application relates to the wireless communications field, for example, is applicable to a wireless local area network supporting the 802.11be standard, and in particular, to a PPDU uplink bandwidth indication method and a related apparatus. The method includes: An AP generates and sends a trigger frame. The trigger frame carries first indication information, where the first indication information directly indicates or jointly indicates an EHT TB PPDU bandwidth or an uplink PPDU total transmission bandwidth. The trigger frame carries second indication information, where the second indication information indicates distribution of an HE TB PPDU and/or an EHT TB PPDU in the uplink PPDU total transmission bandwidth, or directly indicate whether an EHT station transmits an HE TB PPDU or an EHT TB PPDU.
