A communication method and a related apparatus are provided, relate to the field of communication technologies, and may be applied to a
wireless local area network system that supports 802.11 series protocols such as a next-generation Wi-Fi protocol of IEEE 802.11ax, like 802.11be, Wi-Fi 7, or EHT, and a next generation of 802.11be, like Wi-Fi 8, UHR, or Wi-Fi AI. A first AP generates and sends a first communication frame, and a first non-AP STA receives and parses the first communication frame. The first communication frame includes first information and second information, the first information indicates first
time information corresponding to the first AP, and the second information indicates an offset between the first
time information and
start time of an RTWT SP of a second AP. According to the method, the
start time of the RTWT SP of the second AP can be determined.
