Document Type and Number:
Japanese Patent JP4652484
Kind Code:
B2
Abstract:
Provided is a sequence allocation method capable of reducing inter-cell interference of a reference signal when a ZC sequence is used as the reference signal in a mobile communication system. The sequence allocation method divides R x M sequences specified by a ZC sequence number r(r = 1 to R) and a cyclic shift sequence number m (m = 1 to M) into a plurality of sequence groups X in accordance with the transmission band width of the reference signal. When it is assumed that R = 9 and M = 6, the number of sequences is 54. Each of the sequence groups is formed by two sequences. Accordingly, the number of sequence groups is 27. The 27 sequence groups are allocated among the cells.
