Abstract: A user terminal apparatus includes a receiver to receive control information, and a data processor, coupled to the receiver, to select a sequence from a subset of different sequences. The difference sequences are based on a base sequence, and the subset of different sequences depends on the control information. The different sequences are respectively associated with different message sizes or different radio conditions at the user terminal apparatus, have different cyclic shifts, and are arranged in an order of increasing cyclic shift. A transmitter, coupled to the data processor, transmits the selected sequence.

Abstract: Apparatus for use in a mobile radio station includes a memory to store a table of adaptable associations between control information and code sequences. A data processor detects a condition and dynamically adapts one or more of the associations in the table stored in memory between control information and code sequences depending on the detected condition. A transmitter transmits one of the code sequences selected based on the dynamically adapted one or more of the associations.

Abstract: A terminal apparatus and retransmission control method reduces overhead of the uplink control channel in cases when ARQ is applied in communication that uses an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band. A first condition is set in which downlink assignment control information is transmitted from a base station by a unit band group which comprises a basic unit band, which is the downlink unit band on which a broadcast channel signal including information relating to the uplink unit band is transmitted, and a second downlink unit band other than the basic unit band. A bundling unit will not transmit a response signal to the base station in certain cases.

Abstract: Integrated circuitry for use in a mobile radio station includes a receiver that receives control information and a data processor coupled to the receiver. The data processor provides a number of different sequences that are derived from a base sequence. The different derived sequences are respectively associated with different amounts of data or reception qualities, have different cyclic shifts, and are arranged in an increasing order of the cyclic shifts. The data processor randomly selects a sequence from a subset of the derived sequences. The subset of derived sequences depends on the control information.

Abstract: Provided is a radio communication device which can suppress inter-code interference between an ACK/NACK signal and a CQI signal which are code-multiplexed. A diffusion unit (214) diffuses the ACK/NACK signal inputted from a judgment unit (208) by using a ZC sequence. A diffusion unit (219) diffuses the CQI signal by using a cyclic shift ZC sequence. By using a Walsh sequence, a diffusion unit (216) further diffuses the ACK/NACK signal which has been diffused by using the ZC sequence. A control unit (209) controls the diffusion unit (214), the diffusion unit (216), and the diffusion unit (219) so that the minimum value of the difference between the CQI signals from a plurality of mobile stations and a cyclic shift amount of the ACK/NACK signal is not smaller than the minimum value of the difference between the cyclic shift amounts of the ACK/NACK signals from the plurality of mobile stations.

Abstract: A radio communication apparatus includes spreading circuitry that spreads a response signal using a first set of orthogonal sequences to produce a spread response signal. Each orthogonal sequence in the first set has a first length. The spreading circuitry also spreads a reference signal using a second set of orthogonal sequences to produce a spread reference signal. Each orthogonal sequence in the second set has a second length that is shorter than the first length. A radio transmitter transmits the spread response signal and the spread reference signal.
