    摘要： Provided is a radio communication device which can prevent generation of mutual correlation peak between ZC sequences and reduce degradation of BLER characteristic of a CS-ZC sequence. In this device, a sequence length adjustment unit (103) truncates or extends the ZC sequence while maintaining the symmetry of the ZC sequence inputted from a ZC sequence generation unit (102) so as to adjust the sequence length to the number of subcarriers equivalent to the transmission bandwidth of a reference signal inputted from a sequence length setting unit (101). More specifically, the sequence length adjustment unit (103) truncates or extends any one of symbols constituting the ZC sequence so as to truncate or extend the ZC sequence. A transmission RF unit (107) transmits the ZC sequence after the sequence length adjustment.

    摘要： Provided is a sequential allocation method which can reduce mutual correlation between different sequential groups while maintaining a number of sequential groups. ST101 sets a sequence length Nb=31 corresponding to an RB number m=3 and a sequence number ub=1. In a first bandwidth from 3RB to 5RB, ST 105 selects a ZC sequence in which a difference from ub/Nb is u/N which is the nearest to 0. In a second bandwidth of 6RB or above, ST106 selects a plurality of sequences in which the difference from ub/Nb is u/N which is near to 0 and 0.5.
