Abstract
When a wireless communication station, which is about to communicate while intermittently receiving a multicast service, transmits, to an access point, a request packet describing information on the multicast service and an intermittent reception request, the access point describes, in a packet, intermittent reception timing information corresponding to the multicast service information described in this request packet, and replies with this packet to the wireless communication station. The wireless communication station reads the intermittent reception timing information from the received packet, and performs transition to the Awake state or the Doze state according to this intermittent reception timing. The access point, on the other hand, transmits the multicast packet to the wireless communication station according to the intermittent reception timing.
