USER APPARATUS, BASE STATION APPARATUS, AND METHOD IN MOBILE COMMUNICATION SYSTEM

摘要

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 receive a downlink control signal and a downlink data signal; a unit configured to prepare acknowledgement information indicating positive acknowledgement or negative acknowledgement for the downlink data signal; a unit configured to prepare the uplink control signal including the acknowledgement information; a unit configured to transmit the uplink control signal using different resources which are different from resources that can be used for an uplink data signal; and a storage unit configured to store predetermined correspondence relationship which uniquely associates resources of the downlink control signal or the downlink data signal with resources used for the uplink control signal.
