FIELD: radio engineering.
SUBSTANCE: as reference signal there used is ZC-sequence with length unambiguously corresponding to transmission band width of reference signal, and as transmission band width decreases and length of sequence of ZC-sequence becomes shorter, the sequence is changed over to shorter time interval; and as transmission band width becomes bigger and length of sequence of ZC-sequence becomes longer, changeover is performed at longer time interval. Thus, reference signal is shaped using ZC-sequence and in compliance with synchronisation in which transmission band width of reference signal and sequence is changed over.
EFFECT: reducing the processing volume or storage volume at keeping randomisation effect of interference from other cells.
