Method and apparatus for sequence distributing and sequence processing in communication system

A communication apparatus, comprising:

• at least one processor, for executing instructions stored in a memory and causing the communication apparatus to perform operations comprising:
• determining sequence generation information based on a time-frequency resource occupation mode corresponding to a first sub-group in a sequence group and information of the sequence group, wherein the sequence group comprises a plurality of sub-groups, each sub-group comprises at least one sequence, and each sub-group in the sequence group corresponds to a different time-frequency resource occupation mode, wherein the sequence group corresponds to time-frequency resources having different sampling intervals in a frequency domain, the first sub-group corresponds to a time-frequency resource having a sampling interval equal to or larger than 2, and every two adjacent sub-carriers in the first sub-group have the sampling interval;
• and
• generating, according to the sequence generation information, a sequence.
