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： An energy controller, as a communication device, transmits and receives data by transmitting a signal for establishing transmission and reception of the data to network-connected home appliances. The energy controller includes a power saving control unit that determines a transmission period such that the transmission period during which the signal is transmitted is increased as a power value difference increases, which is a value obtained by subtracting the total power consumption value of a power consumption appliance from available power supply value to the power consumption appliance including the network-connected home appliances; and a wireless communication IF for transmitting the signal containing the information indicating the transmission period to the network-connected home appliances in order to set the network-connected home appliances in an active state with a period according to the transmission period.

摘要： A wireless communication system includes a wireless terminal and a plurality of base stations that can communicate with each other via a predetermined communication path that is different from the wireless communication path to the wireless terminal. The wireless terminal transmits a request signal to one of the base stations to request a response signal from another base station. The one base station transfers the received request signal to the other base station via the predetermined communication path. Upon reception of the request signal transferred from the one base station, the second base station transmits a response signal to the wireless terminal via the predetermined channel. The wireless terminal receives the response signal transmitted from the second base station via the predetermined channel.
