The process includes: receiving downlink control information and downlink data; determining, 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 transmitting the response signal using the determined PUCCH resource. 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 repeatedly for one of plural repetition levels in a plurality of subframes, where the first offset is configured for each of the plural repetition levels. The first offset is different from a second offset, which is used when the terminal is not configured in the coverage enhancement mode. ## Claims ### Claim 1 An integrated circuit to control a process for a terminal, the process comprising: receiving downlink control information and downlink data;
