  • Patent number: 11005601
    Abstract: In a case of a contention-based radio communication technique, it is necessary to identify a terminal apparatus that has performed data transmission among terminal apparatuses sharing frequency resources. There is a problem that it is difficult to identify the terminal apparatus that has performed data transmission in a case with a large number of terminal apparatuses that are non-orthogonally spatial multiplexed. Provided is a transmission device for transmitting a data signal to a reception device, the transmission device including: a transmission processing unit configured to transmit the data signal without performing SR transmission or receiving control information of transmission permission transmitted from the reception device; an identification signal multiplexing unit configured to multiplex an identification signal to an orthogonal resource; and a control information receiving unit configured to receive in advance a transmission parameter relating to transmission of the data signal.
