Communication apparatus, transmitting method and receiving method

A communication apparatus comprising:

• a receiver configured to perform receiving processing of data transmitted at each of a plurality of timings which comes every time a given interval elapses;
• a transmitter configured to transmit a first signal indicating that data is successfully received when the data transmitted at a first timing is successfully received;
• and
• a controller configured to transmit a second signal indicating that the data is successfully received, after the first signal is transmitted, when an advance notice of a retransmission of the data is received or an actual reception of the retransmission of the data is performed, and perform a control for providing a period in which any receiving processing on a retransmission of the data is not performed until a second timing, wherein
• the first timing being one of the plurality of timings;
• and
• the second timing being one of the plurality of timings and subsequent to the first timing.

A receiving method of a communication apparatus comprising:

• performing receiving processing of data transmitted at each of a plurality of timings which comes every time a given interval elapses;
• transmitting a first signal indicating that data is successfully received when the data transmitted at a first timing is successfully received;
• and
• transmitting a second signal indicating that the data is successfully received, after the first signal is transmitted, when an advance notice of a retransmission of the data is received or an actual reception of the retransmission of the data is performed, and performing a control for providing a period in which any receiving processing on a retransmission of the data is not performed until a second timing, wherein
• the first timing being one of the plurality of timings;
• and
• the second timing being one of the plurality of timings and subsequent to the first timing.
