1. 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;

    selecting, by the communication system, a sequence from a candidate sequence collection corresponding to each sub-group to form the sequences in the sub-group by;

    selecting, by the communication system, n sequences in the candidate sequence collection to form sequences in a sub-group i in a sequence group k, wherein n is a natural number, i is a serial number of the sub-group, k is a serial number of the sequence group,determining by the communication system, a value of a basic sequence index ri in the sub-group i in the sequence group k, the value of ri;

    is at least one of └

    Ni/N1



    1, wherein Ni is a length of a sequence in the candidate sequence collection, N1 is a length of a reference sub-group sequence;

    allocating, by the communication system, the sequence group to at least one of;

    a base station, a cell, a user equipment and a channel.
