    Abstract: It is an object to provide a sequence allocating method that, while maintaining the number of Zadoff-Chu sequences to compose a sequence group, is configured to make it possible to reduce correlations between different sequential groups. This method comprises the steps of setting a standard sequence with a standard sequence length and a standard sequence number in a step, setting a threshold value in accordance with an RB number in a step, setting a sequence length corresponding to RB number in a step, judging whether ¦r/N-rb/Nb¦=Xth(m) is satisfied in a step, including a plurality of Zadoff-Chu sequences with a sequence number and a sequence length in a sequence group in a step if the judgment is positive, and allocating the sequence group to the same cell in a step.

    Abstract: It is an object to provide a sequence allocating method that, while maintaining the number of Zadoff-Chu sequences to compose a sequence group, is configured to make it possible to reduce correlations between different sequential groups. This method includes the steps of setting a standard sequence with a standard sequence length (Nb) and a standard sequence number (rb) in a step (ST101), setting a threshold value (Xth(m)) in accordance with an RB number (m) in a step (ST103), setting a sequence length (N) corresponding to RB number (m) in a step (ST104), judging whether ¦r/N−rb/Nb¦=Xth(m) is satisfied in a step (ST106), including a plurality of Zadoff-Chu sequences with a sequence number (r) and a sequence length (N) in a sequence group (rb) in a step (ST107) if the judgment is positive, and allocating the sequence group (rb) to the same cell in a step (ST112).

    Abstract translation: 本发明的目的是提供一种在保持Zadoff-Chu序列的数量以构成序列组的同时，使得可以减少不同顺序组之间的相关性的序列分配方法。 该方法包括以下步骤：在步骤（ST101）中设置标准序列长度（Nb）和标准序列号（rb）的标准序列，根据RB号设置阈值（Xth（m）） 在步骤（ST103）中，在步骤（ST104）中设定与RB编号（m）相对应的序列长度（N）（步骤（ST104）），判断是否满足{r / N-rb /Nb≤Xth 步骤（ST106），如果判断为肯定，则在步骤（ST107）中包括序列号（rb）中的序列号（r）和序列长度（N）的多个Zadoff-Chu序列，并且分配序列 组（rb）到步骤中的相同单元（ST112）。
