## Abstract

The present invention pertains to a terminal device, which, when ARQ is used for communication that uses an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band, and when a transmission mode that supports up to 2 TB in a PCell is set in the terminal, is capable of reducing the amount of signaling from a base station while eliminating a lack of PUCCH resources when semi-permanent scheduling (SPS) is used in the PCell. A control unit in this device selects one value among values obtained by adding 1 to four PUCCH resource indexes, which have been preset for PUCCH resource 1 by the base station, on the basis of values for transmission power control information (TPC command for PUCCH) in a PDCCH, for which notification has been received at the start of SPS.

## Claims

### Claim 1

An integrated circuit comprising:
circuitry, which, in operation, controls
receiving downlink data transmitted on a first component carrier and a second component carrier; and
transmitting a response signal, which is indicative of a plurality of error detection results of the downlink data of the first component carrier and the second component carrier, on either one of a first physical uplink control channel (PUCCH) resource indicated by a first PUCCH resource index or a second PUCCH resource indicated by a second PUCCH resource index,
wherein the first PUCCH resource index is determined based on a value of a transmission power control (TPC) command for an uplink control channel and the second PUCCH resource index is determined based on a value obtained by adding 1 to the first PUCCH resource index.

### Claim 2 (depends on 1)

The integrated circuit according to claim 1, wherein
when the value of the TPC command is 00, the first PUCCH resource index indicates PUCCH resource 1;
when the value of the TPC command is 01, the first PUCCH resource index indicates PUCCH resource 2;
when the value of the TPC command is 10, the first PUCCH resource index indicates PUCCH resource 3; and
when the value of the TPC command is 11, the first PUCCH resource index indicates PUCCH resource 4.

### Claim 3 (depends on 1)

The integrated circuit according to claim 1, wherein
the first component carrier is a primary cell (PCell), which is paired with an uplink component carrier on which the response signal is transmitted; and
the second component carrier is a secondary cell (SCell) that is different from the primary cell.

### Claim 4 (depends on 1)

The integrated circuit according to claim 1, wherein
the plurality of error detection results are each a combination of an acknowledgement (ACK) indicating that an error was not detected, a negative-acknowledgement (NACK) indicating that an error was detected, and a discontinuous transmission (DTX) indicating that reception of a downlink control signal has failed.

### Claim 5 (depends on 1)

The integrated circuit according to claim 1, wherein
the TPC command is included in downlink control information, which indicates activation of a semi-persistent scheduling (SPS).

### Claim 6 (depends on 1)

The integrated circuit according to claim 1, wherein
up to two transport blocks are supported on the first component carrier.

### Claim 7 (depends on 1)

The integrated circuit according to claim 1, comprising:
at least one input coupled to the circuitry, wherein the at least one input, in operation, inputs data; and
at least one output coupled to the circuitry, wherein the at least one output, in operation, outputs data.
