COMMUNICATION APPARATUS AND COMMUNICATION METHOD
First Claim
1. A communication apparatus comprising:
- a receiver, which, in operation, receives a higher layer signaling that indicates a reference configuration pattern that is a reference uplink/downlink (UL/DL) configuration, which is one of a plurality of configuration patterns, each configuration pattern defining allocation of one or more uplink subframe(s) and one or more downlink subframe(s) within a frame and, in operation, receives a downlink signaling for determining a configuration pattern for a component carrier;
control circuitry, which, in operation, determines, if the downlink signaling is received, and the configuration pattern for the component carrier according to the received downlink signaling, wherein when the determined configuration pattern is different from the reference UL/DL configuration, the reference UL/DL configuration defines the allocation of the one or more uplink subframe(s) that are inclusive of one or more second uplink subframes defined by the determined configuration pattern, and the reference UL/DL configuration defines at least one more uplink subframe than defined by the determined configuration pattern; and
a transmitter which, in operation, transmits an uplink signal on an uplink subframe of the component carrier, the uplink subframe being one of the one or more second uplink subframes defined by the determined configuration pattern.

Abstract
The purpose of the present invention is to inhibit an increase in the amount of A/N resources, without changing the timing at which the error detection result of an SCell is notified when UL-DL configurations to be configured for each of the unit bands are different, from the timing at which the error detection result is notified when just a single unit band is configured. A control unit transmits, using a first unit band, a response signal including error detection results about data received with both the first unit band and a second unit band. In a first composition pattern set for the first unit band, an uplink communication subframe is set to be the same timing as at least an uplink communication subframe of a second composition pattern set for the second unit band.

9. A communication method comprising:
-
receiving a higher layer signaling that indicates a reference configuration pattern that is a reference uplink/downlink (UL/DL) configuration, which is one of a plurality of configuration patterns, each configuration pattern defining allocation of one or more uplink subframe(s) and one or more downlink subframe(s) within a frame and receiving a downlink signaling for determining a configuration pattern for a component carrier; determining, if the downlink signaling is received, and the configuration pattern for the component carrier according to the received downlink signaling, wherein when the determined configuration pattern is different from the reference UL/DL configuration, the reference UL/DL configuration defines the allocation of the one or more uplink subframe(d) that are inclusive of one or more second uplink subframes defined by the determined configuration pattern, and the reference UL/DL configuration defines at least one more uplink subframe than defined by the determined configuration pattern; and transmitting an uplink signal on an uplink subframe of the component carrier, the uplink subframe being one of the second one or more uplink subframes defined by the determined configuration pattern. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
