Abstract
An access point transmits data frames to a plurality of wireless terminals by MC or BC communication. When the data frames are transmitted, data to identify the presence of the return of an ACK frame as affirmative acknowledgment with respect to transmitted contents is applied to an MAC header. In a case where a Block ACK frame is requested as affirmative acknowledgment with respect to the transmission of a plurality of frames in the MC or BC communication, the plurality of wireless terminals return the Block ACK frame to the access point and the wireless terminals other than the wireless terminal itself by the MC or BC communication.
