Abstract
The present invention discloses a method and a device for sequencing the ZC sequences of the random access channel. The method for sequencing the ZC sequences includes the following steps: Step 202, ZC sequences are divided into a plurality of groups according to the cubic metrics of the ZC sequences; Step 204, the ZC sequences are sequenced, according to the maximum cyclic shift supported by the ZC sequences under a high speed circumstance, within each group to form a plurality of sub-groups; and Step 206, the ZC sequences within each of the plurality of sub-groups are sequenced according to the cubic metrics of the ZC sequences, wherein, the adjacent sub-groups in the same group are sequenced in different orders, while the sub-groups at the boundary of the two adjacent groups are sequenced in the same order. Thereby, the sequences could be assigned according to the CMs, and the sequence fragments could be collected for use.
