1. A method, comprising:
performing, by a station (STA) in a multi-link (ML) entity, a backoff procedure on a first link; and
sending, by the station, a first physical layer protocol data unit (PPDU) on a second link, wherein the second link is the first link whose backoff procedure has ended and that is in an idle state in a first inter-frame space before a first time point,
wherein:
the ML entity supports K first links, the first link is one of the K first links, K is an integer greater than or equal to 2, and a backoff procedure is performed on each first link in the K first links,
the second link is one of N second links, the N second links are a subset of the K first links, and N is a positive integer less than or equal to K, and
the first time point is an end time point of a backoff procedure of a target link, and the target link is a second link whose backoff procedure ends last in the N second links.
