Patent ID: 8588168

Claim:
A method for allocating sequences in a communication system, comprising: dividing, by a communication system, sequences in a sequence group into multiple sub-groups, each sub-group corresponding to a mode of occupying time frequency resources; sending, by the communication system, a sequence of the sub-groups in a sequence group k to at least one of: a base station, a cell, a user equipment, and a channel; wherein the sequence of a sub-group i satisfies r i =└N l c k /N p 1 +1/2┘, wherein r i is a basic sequence index in a candidate sequence collection, and N i is a length of a sequence in the candidate sequence collection, N p 1 is the length of a reference sub-group sequence, and c k is a basic sequence index of a sequence with N p 1 determined by the sequence group k.
