Abstract: A non-AP MLD or a first STA in the non-AP MLD generates a first frame. The first frame includes indication information for indicating padding duration for a channel switch delay in an initial control frame. The padding duration is determined based on duration of a control response frame. The non-AP MLD or the first STA or another STA in the non-AP MLD transmits the first frame. An AP MLD or a first AP or another AP in the AP MLD receives the first frame. The AP MLD or the first AP determines the padding duration of the initial control frame based on the indication information.

Abstract: In a communication method, a first access point (AP) in a first AP multi-link device generates a management frame that includes a capability information field. The capability information field includes first indication information indicating whether a second AP, which is also in the first AP multi-link device, has performed a channel switch. The first AP then sends the management frame to a first station (STA).
