摘要： According to one embodiment, a communication apparatus includes a radio interface unit that sends a data message to a receiver and extracts, when a message sent by the receiver via unicast with an optimized transmission rate is received, rate information indicating the optimized transmission rate of the receiver from the received message, a message processor that generates the data message, in which a multicast identifier indicating a multicast group is a destination, and outputs the data message to the radio interface unit, and a selector that selects, according to the rate information, a data message transmission rate to send the data message.
