Abstract:
[Object] To provide a communication apparatus and a communication method that enable reinforcement of reliability of multicast communication and effective utilization of wireless communication resources to be compatible.
[Solution] Provided is a communication apparatus including: a communication unit configured to perform communication of a frame. The communication unit transmits a frequency allocation frame, which includes frequency allocation information that specifies a transmission frequency of a delivery acknowledgment response frame with respect to a multicast frame, and receives the delivery acknowledgment response frame that is transmitted in the transmission frequency specified by the frequency allocation information and is frequency-division multiplexed.
