<p>An object of the present invention is to suppress quality deterioration of a multicast packet due to transmission delay jitter. An access point comprises: a received packet analysis unit which extracts, from a packet transmitted from a wireless communication station, identification information for identifying a wireless communication station, MC reception information to indicate whether the wireless communication station receives a multicast packet or not, and communication operation information to indicate whether the communication operation of the wireless communication station is set to PS mode or not; an STA table management unit which generates an STA table associating the extracted identification information, MC reception information and communication operation information, and stores this STA table in a memory; and a packet transmission timing control unit which controls a transmission timing of the multicast packet based on the STA table stored in the memory.</p> |
