摘要： Retransmission control and retransmission are performed at a lower priority than the transmission of multicast packets from a transmission apparatus to two or more reception apparatuses. A communication apparatus performs wireless multicast transmission to reliable transmit packets. In a transmission side terminal, sequence numbers are attached at a layer higher than the Mac layer to each of secured-bandwidth or priority control-type Mac layer multicast packets, and in a plurality of reception side terminals, missing packets are detected using the sequence numbers, and bandwidth other than the secured bandwidth or lower priority packets are used to perform retransmission requests. The transmission terminal retransmits data using bandwidth other than the secured bandwidth or lower priority packets, thereby enabling favorable reception of audio, video and data when transmitting the audio, video and data in real-time to the reception terminals using wireless secured bandwidth-type or priority control-type Mac layer multicast transmission.

摘要： A signal transmitted to an STA 200a from a communication device AP is also received by an STA 200b. Upon reception, the STA 200b measures an RSSI. The STA 200b then creates a state notice frame which includes the measured RSSI, and transmits it to the AP 100. In accordance with the received state notice frame, the AP 100 determines and updates a PHY rate for transmission to the STA 200b. This allows to increase the determination and update frequency of PHY rates than before, resulting in an improved possibility of coping with rapid changes in channel environments.
