Communication apparatus and communication method

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.

1 . A communication apparatus comprising:
 one or more circuits configured to perform communications of a frame,   wherein the one or more circuits are configured to   transmit 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   receive the delivery acknowledgment response frame that is transmitted in the transmission frequency specified by the frequency allocation information and is frequency-division multiplexed,   
       wherein the frequency allocation information includes information that specifies a bandwidth of the transmission frequency and setting period information that specifies a period in which the transmission frequency specified by the frequency allocation information is to be set to a communication frequency. 
     
     
         2 . A communication apparatus comprising:
 one or more circuits configured to perform communications of a frame,   wherein the one or more circuits are further configured to   receive 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   transmit the delivery acknowledgment response frame using the transmission frequency specified by the frequency allocation information, and   the delivery acknowledgment response frame is frequency-division multiplexed,   
       wherein the frequency allocation information includes information that specifies a bandwidth of the transmission frequency and setting period information that specifies a period in which the transmission frequency specified by the frequency allocation information is to be set to a communication frequency. 
     
     
         3 . A communication method performed by one or more circuits, the method comprising:
 performing communication of a frame;   transmitting 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   receiving the delivery acknowledgment response frame that is transmitted in the transmission frequency specified by the frequency allocation information and is frequency-division multiplexed,   
       wherein the frequency allocation information includes information that specifies a bandwidth of the transmission frequency and setting period information that specifies a period in which the transmission frequency specified by the frequency allocation information is to be set to a communication frequency. 
     
     
         4 . A communication method performed by one or more circuits, the method comprising:
 performing communication of a frame;   receiving 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   transmitting the delivery acknowledgment response frame using the transmission frequency specified by the frequency allocation information,   wherein the delivery acknowledgment response frame is frequency-division multiplexed, and   
       wherein the frequency allocation information includes information that specifies a bandwidth of the transmission frequency and setting period information that specifies a period in which the transmission frequency specified by the frequency allocation information is to be set to a communication frequency.
