Method and apparatus for sequence distribution and processing in a communication system

A sequence allocation, sequence processing method and device in a communication system. The sequence allocation method comprises the steps of: generating a sequence group comprising a plurality of sequences, the sequences within the sequence group being determined according to a sequence time-frequency resource occupation manner supported by the system; and assigning the sequence group to the cells. By assigning a sequence group containing multiple sequences to the cell, the method avoids the phenomenon that the signaling mode is required to allocate a sequence to the cell for different time-frequency resource occupation modes, and saves the wireless network transmission resource occupied during the allocation sequence as much as possible. .
