Claim Text:
1. A mobile station transmitting an uplink signal according to a single-carrier scheme, comprising: a selecting unit adapted for a system, wherein multiple frequency bandwidths of different sizes are defined, each of the frequency bandwidths being expressed by a multiple of a minimum frequency bandwidth, wherein a set of signal sequences is defined for each of the frequency bandwidths, wherein multiple sequence groups are defined such that each of the sequence groups includes signal sequences selected from every one of multiple sets of the signal sequences defined for the frequency bandwidths and the signal sequences in each of the sequence groups are different from each other, and wherein the selecting unit being configured to select a sequence group from the sequence groups; a determining unit configured to determine a signal sequence that is included in the selected sequence group and corresponds to one of the frequency bandwidths; a generating unit configured to generate a reference signal based on the determined signal sequence; and a transmitting unit configured to transmit the reference signal generated by the generating unit.
