1. A method for data transmission, applied to a transmitting device, comprising:
when performing resource mapping of data to be transmitted on a first symbol of a wireless transmission resource which is allocated to the transmitting device, selecting, according to a serial number interval acquired in advance, target subcarriers at an equal interval in a frequency domain of the wireless transmission resource;
mapping the data to be transmitted to each of the target subcarriers in a frequency domain;
modulating each of the target subcarriers by using the data to be transmitted to obtain a time domain symbol;
setting information in a forwardmost part of the time domain symbol to 0 to obtain an output symbol, the forwardmost part having a preset length, wherein the preset length is equal to y/x, y is a positive integer less than x, and x is the serial number interval; and
transmitting the output symbol.
