40. A communication control method, comprising:
controlling communication of a data frame, including controlling
multicasting, by circuitry configured to perform communication of a data frame before the multicasting, 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 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, the frequency allocation information being specified for each of the association identifiers.
