Claim Text:
1. A method for allocating sequences in a communication system that includes a network entity and at least one cell, comprising: determining, by the network entity, a sequence group comprising a plurality of sequences, wherein the sequences in the sequence group correspond to occupation modes of time-frequency resources supported in the system; and allocating the sequence group to the at least one cell, wherein a sequence for use by a network side equipment, which the cell belongs to, or a user equipment in communication with the network side equipment is determined from the sequence group according to an occupation mode of the time-frequency resources of the network side equipment or the user equipment; wherein the sequences in the sequence group correspond to occupation modes of time-frequency resources in one or more of the following manners: different sequences correspond to the time-frequency resources having different bandwidths; different sequences correspond to the time-frequency resources having different sampling intervals; and different sequences correspond to different positions of time-frequency resource blocks; wherein the sequences in the sequence group comprises one or more of the following: a constant amplitude zero auto-correlation (CAZAC) sequence, a fragment of a CAZAC sequence, and a sequence obtained through combining a CAZAC sequence with a segment of a CAZAC sequence; wherein the CAZAC sequence is a Zadoff-Chu sequence; wherein when the sequences in the sequence group correspond to the occupation modes of the time-frequency resources in the manner of different sequences correspond to the time-frequency resources having different bandwidths, two sequences occupying the time-frequency resources having different bandwidths are taken as two of the sequences in the sequence group; wherein indexes r
