Abstract
A user apparatus transmits an uplink control signal to a base station apparatus using a single carrier scheme. The user apparatus includes: a unit configured to prepare acknowledgement information indicating positive acknowledgement or negative acknowledgement for a downlink data signal based on a result of demodulation of the downlink data signal; a unit configured to prepare channel state information indicating reception quality of a downlink reference signal; a unit configured to channel-code multiplexed control information in which the acknowledgement information and the channel state information are multiplexed to prepare the uplink control signal; and a unit configured to transmit the uplink control signal using dedicated resources different from resources for an uplink data signal.
