Abstract: Embodiments of this disclosure disclose a multi-link communication method and a related apparatus. In a scenario in which simultaneous transmission and reception over a plurality of links is not supported, a multi-link device first sends a first physical layer protocol data unit (PPDU) over a first link, and then sends a second PPDU over a second link through channel contention, where an end time of the second PPDU is not later than an end time of the first PPDU. The method not only ensures fairness of multi-link access, but also can reduce an idle rate of the plurality of links.
