1. A multi-link group addressed traffic transmission method, comprising:
receiving, by a first station (STA) of a station multi-link device (STA MLD) from a first access point (AP) of an AP MLD, group addressed traffic indication information comprising a set of bits in a partial virtual bitmap field in a traffic indication map (TIM) element, wherein the set of bits in the partial virtual bitmap field in the TIM element indicates whether each AP of one or more second APs has a group addressed traffic, the one or more second APs being one or more other APs of the AP MLD except the first AP; and
determining, by the first STA, based on the group addressed traffic indication information, whether the one or more second APs have a group addressed traffic.
