Abstract
A user device for a mobile communication system employing a multicarrier scheme is disclosed. The user device includes a control signal generating unit for generating a control signal. The user device also includes a transmitting unit for transmitting the control signal to a base station. The control signal sent by the user device is mapped to multiple frequency bands throughout a time period of a subframe but separated from each other in a frequency domain. Each of the frequency bands includes subcarriers used in orthogonal frequency division multiplexing.
