Claim Text:
1. An integrated circuit to control a process performed at a mobile station, the process comprising: receiving information related to a set of sequences configured to be available in a cell for use by the mobile station, the information being broadcasted from a base station; selecting a sequence from the set of sequences available in the cell; and random-access-preamble-transmitting the selected sequence; wherein the set of sequences available in the cell includes a sequence of r=a and a sequence of r=N−a, where r is a sequence number, a is an integer, and N is a sequence length, and the allocated sequences are defined by the following equation or an equation cyclic shifted from the following equation: where k=0, 1, 2, . . . N−1, and q is an integer, and the sequence of r=a and the sequence of r=N−a are conjugate to each other.
