The invention discloses a sorting method and device of random access channel ZC sequence. The method includes: step 1, ZC sequences are divided into a low cube measure group and a high cube measure group according to a QPSK cube measure to ensure every ZC sequence index in the low cube measure group is less or more than every sequence index in the high cube measure group; step 2, the sequences in the low cube measure group and the high cube measure group are respectively divided into S subgroups by S-1 biggest circle shift thresholds according to a supporting biggest cell radius or biggest circle shifts of the ZC sequence in a high speed environment; step 3, the sequences are sorted in every subgroup according to the cube measure of the ZC sequence, thereby, the ZC sequence in contiguous subgroups of the low cube measure group and the high cube measure group have different orders, and the sequences in contiguous subgroups of the low cube measure group and the high cube measure group have the same order.
(ZH) 本发明公开了随机接入信道的ZC序列排序方法和装置，该方法包括：步骤一，根据QPSK的立方度量，将ZC序列分成低立方度量组和高立方度量组，使得低立方度量组内每条ZC序列的索引小于或者大于高立方度量组内每条序列的索引；步骤二，根据ZC序列在高速环境下所支持的最大小区半径或最大循环移位量，用S-1个最大循环移位门限分别将低立方度量组和高立方度量组内的序列分成S个子组；步骤三，根据ZC序列的立方度量，在各子组内，对序列进行排序，使得在低立方度量组和高立方度量组内，相邻子组内的ZC序列具有不同的排序顺序以及低立方度量组和高立方度量组相邻的子组内的序列具有相同的排序顺序。
