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.
