1. A method, comprising:
receiving, by an access point (AP) in an AP multi-link device (AP MLD), a first frame, from a first station (STA) in a STA multi-link device (STA MLD), the first frame comprises first information indicating how often at least one STA of a plurality of STAs in the STA MLD listens to a beacon frame when the plurality of STAs in the STA MLD are in a power saving mode,
wherein how often the at least one STA of the plurality of STAs in the STA MLD listens to the beacon frame is indicated by a time interval within which the at least one STA of the plurality of STAs in the STA MLD listens to the beacon frame, a unit of the time interval is a largest time interval of a plurality of beacon frame intervals at which the AP MLD sends beacon frames on a plurality of links corresponding to the plurality of STAs participating in an association establishment process with the AP MLD; and
sending, by the AP in an AP MLD, a second frame based on first information, to the first STA in the STA MLD.
