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

摘要

A user device transmits an upstream control signal to a base station device by a single carrier method. The user device includes: means for receiving a downstream control signal and a downstream data signal; means for preparing a transmission check information indicating an affirmative response or a negative response to the downstream data signal; means for preparing a control signal containing transmission check information; means for transmitting an upstream control signal by a resource different from a resource which can be used for the upstream data signal; and storage means for storing a predetermined correlation which uniquely definesthe correspondence between the resource of the downstream control signal or the downstream data signal and the resource used for the upstream control signal.
