Abstract
A PUCCH resource collision between a normal mode terminal and MTC coverage enhancement mode terminal is avoided. A terminal includes a receiving section that receives control information indicating assignment of downlink data, and the downlink data; and a transmitting section that transmits a response signal using a resource in a first resource group when the terminal is a first terminal to which repetition transmission is applied, and that transmits the response signal using a resource in a second resource group that is different from the first resource group, when the terminal is a second terminal to which the repetition transmission is not applied.
Claims22
A terminal comprising:
- a receiver, which, in operation, receives downlink control information and downlink data;
- circuitry, which, in operation, determines, based on the downlink control information and an offset, a physical uplink control channel (PUCCH) resource used for transmission of a response signal for the downlink data;
- and
- a transmitter, which, in operation, transmits the response signal using the determined PUCCH resource,
- wherein:
- a first offset is used as the offset when the terminal is configured in a coverage enhancement mode, in which the response signal is allowed to be transmitted a repetition level N times repeatedly spanning a plurality of subframes, where the repetition level N is a positive integer, and the first offset is one of plural offsets that are configured for plural values of the repetition level N, respectively;
- and
- the first offset is different from a second offset, which is used when the terminal is not configured in the coverage enhancement mode.

- and
- a transmitter, which, in operation, transmits the response signal using the determined PUCCH resource,
- wherein:
- a first offset is used as the offset when the receiver receives the downlink control information which is allowed to be transmitted across a repetition level N subframes in a coverage enhancement mode, where the repetition level N is a positive integer, and the first offset is one of plural offsets that are configured for plural values of the repetition level N, respectively;
- and
- the first offset is different from a second offset, which is used when the terminal is not configured in the coverage enhancement mode.
