Communication device and communication method

A communication device, comprising:

• one or more circuits configured to perform communication of a data frame, wherein the one or more circuits are configured to:
• receive, after the communication of the data frame, a block acknowledgment request (BAR) frame for a block acknowledgment (BA) frame including frequency allocation information specifying a transmission frequency of the BA frame, the BAR frame being multicast, the BA frame acknowledging the data frame, and
• transmit the BA frame on the basis of the frequency allocation information, the BA frame being frequency division multiplexed, wherein
• the BAR frame includes a receiver address field storing an identifier of a multicast group specifying destinations of the BAR frame and identification information fields specifying each of one or more destinations of the BAR frame, the identification information being association identifiers of the one or more destinations selected from the multicast group, and
• the frequency allocation information includes a first piece of information for each of the one or more destinations selected from the multicast group individually and a second piece of information common to all of the one or more destinations selected from the multicast group.

A communication method, comprising:

• multicasting, by circuitry configured to perform communication of a data frame before the multicasting, a block acknowledgment request (BAR) frame for a block acknowledgment (BA) frame including frequency allocation information specifying a transmission frequency of the BA frame, the BA frame acknowledging the data frame communicated from the circuitry;
• and
• receiving the BA frame which is frequency division multiplexed on the basis of the frequency allocation information, wherein
• the BAR frame includes a receiver address field storing an identifier of a multicast group specifying destinations of the BAR frame and identification information fields specifying each of one or more destinations of the BAR frame, identification information being association identifiers of the one or more destinations selected from the multicast group, and
• the frequency allocation information includes a first piece of information for each of the one or more destinations selected from the multicast group individually and a second piece of information common to all of the one or more destinations selected from the multicast group.

A non-transitory computer readable storage device having computer readable instructions that when executed by circuitry cause the circuitry to perform control:

• to transmit, by multicast after communication of a data frame, a block acknowledgment request (BAR) frame for a block acknowledgment (BA) frame including frequency allocation information specifying a transmission frequency of the BA frame, the BA frame acknowledging the data frame communicated from a communication device, and
• to receive the BA frame which is frequency division multiplexed, on the basis of the frequency allocation information, wherein
• the BAR frame includes a receiver address field storing an identifier of a multicast group specifying destinations of the BAR frame and identification information fields specifying each of one or more destinations of the BAR frame, identification information being association identifiers of the one or more destinations selected from the multicast group, and
• the frequency allocation information includes a first piece of information for each of the one or more destinations selected from the multicast group individually and a second piece of information common to all of the one or more destinations selected from the multicast group.
