Abstract:
1. A method for allocating sequences in a communication system, comprising: generating a sequence group comprising a plurality of sequences, wherein the sequences in the sequence group are determined according to occupation modes of time-frequency resources of the sequences supported in the system; wherein the sequences in the sequence group at least comprises one of the following: constant amplitude zero auto-correlation (CAZAC), sequence, a fragment of CAZAC sequence, and the sequence obtained through combining a CAZAC sequence with a fragment of a CAZAC sequence; wherein the CAZAC sequence is a Zadoff-Chu sequence; wherein when the occupation modes of time-frequency resources of the sequences at least comprise: different sequences occupying the time-frequency resources having different bandwidths, the generating a sequence group comprising a plurality of sequences comprises: taking two sequences occupying the time-frequency resources having different bandwidths as the sequences in the sequence group; wherein indexes r and allocating the sequence group to a cell.
