Provided is a method sending an acknowledgment frame, wherein by receiving a data frame sent by the first access point and calculating the minimum transmission power of the present station, the maximum transmission power of the station is used as the initial transmission power; the pre-established queue of the maximum transmission powers of the overlapping basic service set is invoked; the queue is a set of maximum transmission powers which does not affect packet reception of one or more second stations and calculated by the first station; the maximum transmission power of the overlapping basic service set allowed in the pre-established queue is traversed sequentially; being greater than or equal to the minimum transmission power, the minimum value among the initial transmission power and one or more maximum transmission powers is taken as the final transmission power; and the acknowledgment frame is sent by using the determined final transmission power.
