WIRELESS TRANSMISSION TERMINAL, WIRELESS RECEIVING TERMINAL, WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION METHOD, AND PROGRAM

A wireless transmission terminal in which it is possible to set whether or not a response to wirelessly received data is to be wirelessly transmitted, in which priority information indicating the priority of terminals on the receiving side is wireless transmitted, and in which data is wirelessly transmitted in multicast format to a wireless receiving terminal that is a response-enabled terminal for which wireless transmission of the response is enabled or a response-disabled terminal for which wireless transmission of the response is disabled, wherein the wireless communication terminal has: a storage unit in which the maximum number of the response enabled terminals is stored; and a control unit that, when a connection request transmitted from one of the wireless receiving terminals and used to receive the wirelessly transmitted multicast data and the priority information are wirelessly received by a wireless communication unit, causes the priority information to be stored in the storage unit correlated with identification information for identifying the wireless receiving terminal that wirelessly transmitted the connection request.
