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 preparing transmission check information indicating an affirmative response or a negative response to a downstream data signal according to the demodulation result of the downstream data signal; means for preparing channel state information indicating a reception quality of a downstream reference signal; means for channel-encoding multiplex control information multiplexed with the transmission check information and the channel state information so as to prepare an upstream control signal; and means for transmitting the upstream control signal by using a dedicated resource which is different from a resource for an upstream data signal.
