TERMINAL DEVICE, AND BUFFER PARTITIONING METHOD

摘要

Disclosed is a terminal apparatus in which: a decoding section (210) that stores, in a retransmission buffer, downlink data transmitted by each of the plurality of component carriers and decodes the downlink data; and a radio transmitting section (222) that transmits, using a first component carrier of the plurality of component carriers, a response signal for first downlink data received using the first component carrier and a response signal for second downlink data received using a second component carrier of the plurality of component carriers, in addition, a second buffer is divided into regions respectively corresponding to retransmission processes based on a specific value determined by a combination of a first configuration pattern that is set in the first component carrier and a second configuration pattern that is set in the second component carrier.

1. A terminal apparatus which communicates with a base station apparatus using a plurality of component carriers and for which a configuration pattern of subframes included in one frame is set for each of the plurality of component carriers, the configuration pattern including a downlink communication subframe used for downlink communication and an uplink communication subframe used for uplink communication, the terminal apparatus comprising:
a decoding section that stores, in a retransmission buffer, downlink data transmitted in each of the plurality of component carriers and decodes the downlink data; a generating section that generates a response signal using a result of error detection of the downlink data; and a transmitting section that transmits, using a first component carrier of the plurality of component carriers, a response signal for first downlink data received using the first component carrier and a response signal for second downlink data received using a second component carrier of the plurality of component carriers, wherein: the buffer includes a first, buffer that stores the first downlink data and a second buffer that stores the second downlink data; and the second buffer is divided into regions respectively corresponding to retransmission processes based on a specific value determined by a combination of a first configuration pattern that is set in the first component carrier and a second configuration pattern that is set in the second component carrier.
