The invention provides the technical scheme that a modularization implementation method based on the 5G pseudorandom sequence comprises the following steps: S1, carrying out the decomposition according to reference sequence lengths needed by different applications; S2, introducing a pseudo-random sequence module which is integral multiple of 12; S3, carrying out pseudo-random sequence module selection on the redivided sequence; S4, obtaining m sequences in different application environments according to a 3GPP38.211 protocol; S5, carrying out iterative processing on the m sequence according to the length of the sequence required by the corresponding module, and finally obtaining a pseudo-random sequence. According to the method, the used state offset is generated based on the pseudo-random sequence, a state offset module of integral multiple of 12 is re-introduced, the required sequence is re-grouped, and the final pseudo-random sequence is obtained by determining the pseudo-random sequence of the initial position RB; and the system performance is ensured.
