The embodiments of the present disclosure provide a data sequence forming method and apparatus, a storage medium, and an electronic device. The method comprises: dividing N frequency domain resource blocks used for transmitting data to be transmitted into two groups to obtain two groups of frequency domain resource blocks, wherein each group comprises L(m) frequency domain resource blocks, and the two groups of frequency domain resource blocks are distributed alternately in frequency domain, where N and L(m) are both positive integers, and m=1 or 2; and processing data to be transmitted on the L(m) frequency domain resource blocks in each group respectively to form L(m) groups of data sequences. The described technical solution solves the problem in the prior art that interference easily occurs between sub-bands when data sequences are filtered.

Provided in the present disclosure are a data transmission method and apparatus, and a storage medium and an electronic apparatus. The method comprises: transmitting, in N frequency domain resource blocks, data to be transmitted, wherein the N frequency domain resource blocks respectively include the same number K of sub-carriers, K is ith power of 2, i is a positive integer, and N is an integer greater than 1; respectively performing inverse Fourier transform on said data on the K sub-carriers of each frequency domain resource block, so as to form N groups of data sequences, wherein there are 2K points of inverse Fourier transform; performing inverse Fourier transform on the N groups of data sequences, so as to form a group of time domain data sequences, and transmitting the group of time domain data sequences.
