Terminal apparatus, base station apparatus, and communication method

A terminal apparatus that communicates with a base station apparatus, the terminal apparatus comprising:

• a reception unit provided with
• a function of receiving information indicating a labeling method used for a transmit signal that is transmitted from the base station apparatus to the terminal apparatus itself and information relating to a retransmission state of the transmit signal that is transmitted to the terminal apparatus itself;
• and
• a function of receiving a non-orthogonal multiplexing signal that results from the base station apparatus non-orthogonally multiplexing at least some of the transmit signal that is transmitted to the terminal apparatus itself and a transmit signal that is transmitted to another terminal apparatus, for transmission, using the same radio resource;
• and
• a demodulation unit that performs demodulation processing based on the information indicating the labeling method and the information relating to the retransmission state.

A communication method for use in a terminal apparatus that communicates with a base station apparatus, the method comprising:

• a step of receiving information indicating a labeling method used for a transmit signal that is transmitted from the base station apparatus to the terminal apparatus itself and information relating to a retransmission state of the transmit signal that is transmitted to the terminal apparatus itself;
• a step of receiving a non-orthogonal multiplexing signal that results from the base station apparatus non-orthogonally multiplexing at least some of the transmit signal that is transmitted to the terminal apparatus itself and a transmit signal that is transmitted to another terminal apparatus, for transmission, using the same radio resource;
• and
• a step of performing demodulation processing based on the information indicating the labeling method and the information relating to the retransmission state.
