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.

A base station apparatus in a mobile communications system which uses orthogonal frequency division multiplexing (OFDM) for downlink is disclosed. The base station includes a unit which generates a first signal; a unit which generates a second signal; a unit which multiplexes the first signal and the second signal to map the multiplexed signals to a sub-carrier to generate a transmit symbol; and a mapping determining unit which determines a position of mapping the second signal to the sub-carrier, wherein the mapping determining unit determines the mapping position based on a cell ID or cell group ID, and a mapping pattern defined with a sequence having two-stage structure.

摘要:
In the mobile communication system in the multi-carrier CDMA scheme, data to be transmitted by the radio base station are doubly spread by using a long code that is unique to each radio base station and to be used in identifying each radio base station, in addition to a short code to be used in identifying each mobile station. The long code has a repetition period longer than or equal to the number of sub-carriers used for transmission.
