1. An access point (AP) multi-link device (MLD) associated with a non-AP MLD including a first station (STA) and a second STA, the AP MLD comprising:
a first AP affiliated with the AP MLD and associated with the first STA; and
a second AP affiliated with the AP MLD and associated with the second STA,
wherein:
the first AP sets up a first link with the first STA,
the second AP sets up a second link with the second STA,
the first link uses a millimeter wave band,
the second link uses a frequency band below the millimeter wave band,
the first AP transmits a beamforming training signal for the first link to the first STA and receives beamforming feedback information from the first STA when the second link is enabled,
the second AP transmits a beamforming training request includes a start time of a beamforming training procedure for the first link to the second STA via the second link,
the beamforming training request includes beamforming training information for the first link,
the beamforming training information includes a start time of a beamforming training procedure for the first link,
the first AP starts the beamforming training procedure at the start time, and
the second STA transmits the beamforming training information to the first STA and the first STA wakes up at the start time.
