RECEIVING DEVICE, RECEIVING METHOD, AND INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To reduce cross-correlation between different sequence groups while keeping the number of Zadoff-Chu sequences constituting a sequence group.SOLUTION: A receiving method comprises the steps of: setting a reference sequence having reference sequence length Nb and a reference sequence number rb in an ST101; setting a threshold value Xth(m) in accordance with an RB number m in an ST103; setting sequence length N corresponding to the RB number m in an ST104; and when |r/N-rb/Nb|≤Xth(m) is determined in an ST106, containing a plurality of Zadoff-Chu sequences each having a sequence number r and sequence length N in a sequence group rb in an ST107, and allocating the sequence group rb to the same cell in an ST112.
