    摘要： Provided is a communication method for improving the communication quality of multicast transmission. A grouping table storage section stores a grouping table in which Ack return order positions indicating priority orders of the reception terminals which each return an Ack, and addresses of the reception terminals are set. An Ack return order position notification frame creation section notifies each reception terminal of a corresponding Ack return order position based on the grouping table. An Ack return permission information determination section refers to the grouping table, determines the number of reception terminal that are to be permitted to return an Ack, and creates Ack return permission information in which information about the reception terminals that are to be permitted to return an Ack is set, based on the determined number of reception terminals. A multicast creation section creates a multicast containing the Ack return permission information and transmission data.
