1. A beacon frame transmission control method, comprising:
generating, by a master access point (AP), indication information used to indicate a transmission start time point of a beacon frame of at least one secondary AP; and
sending, by the master AP, the indication information to the at least one secondary AP, wherein
the master AP and the at least one secondary AP belong to a same AP collaboration group, and transmission start time points of beacon frames of APs in the AP collaboration group are different;
wherein the beacon frame of the at least one secondary AP is at least one second beacon frame; and
sending, by the master AP, the indication information comprises:
sending, by the master AP, a first beacon frame within a beacon interval (BI) of the master AP, wherein the first beacon frame comprises the indication information, and the indication information is used to indicate a transmission start time point of the at least one second beacon frame;
wherein the BI comprises N equal time periods, wherein N minus 1 is equal to a quantity of secondary APs in the at least one secondary AP;
a transmission time period of the first beacon frame corresponds to a first equal time period in the N equal time periods; and (N−1) equal time periods in the N equal time periods other than the first equal time period are in a one-to-one correspondence with the at least one secondary AP;
wherein the indication information comprises a list of the at least one secondary AP, the list comprises an identifier used to indicate the at least one secondary AP, and a location of the identifier of the at least one secondary AP in the list is in a one-to-one correspondence with the (N−1) equal time periods; and
the transmission start time point of the second beacon frame of the at least one secondary AP is after a transmission end time point of the first beacon frame by an equal time period multiplied by the location of the identifier of the at least one secondary AP in the list.
