Abstract

In the invention, wireless communication devices transmit beacon frames in an order in compliance with a CSMA/CA protocol. A wireless communication device as a transmitting station of a multicast frame uses one of the beacon frames to notify wireless communication devices as receiving stations of the multicast frame that an ACK frame is to be transmitted when the multicast frame is received. On receipt of the multicast frame, the wireless communication devices as the receiving stations transmit ACK frames in order of transmitting the beacon frames at SIFS intervals.
