Patent ID: 8379591

Claim:
A sequence transmission method comprising: selecting a Zadoff-Chu sequence from one of (i) a first group including at least a first Zadoff-Chu sequence having (a sequence index of said first Zadoff-Chu sequence)/(a sequence length of said first Zadoff-Chu sequence) showing a difference from a reference Zadoff-Chu sequence having (a sequence index of said reference Zadoff-Chu sequence)/(a sequence length of said reference Zadoff-Chu sequence) closest to 0, and a second Zadoff-Chu sequence having (a sequence index of said second Zadoff-Chu sequence)/(a sequence length of said second Zadoff-Chu sequence) showing a difference from the reference Zadoff-Chu sequence having (the sequence index of said reference Zadoff-Chu sequence)/(the sequence length of said reference Zadoff-Chu sequence) closest to 0.5 and (ii) a second group including the first Zadoff-Chu sequence and not including the second Zadoff-Chu sequence; and transmitting the selected Zadoff-Chu sequence, wherein: in the event that the selected Zadoff-Chu sequence is transmitted using a first bandwidth, the Zadoff-Chu sequence is selected from the second group; and in the event that the selected Zadoff-Chu sequence is transmitted using a second bandwidth greater than the first bandwidth, the Zadoff-Chu sequence is selected from the first group.
