SEQUENTIAL TRANSMISSION METHOD

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.
