Provided in an embodiment of the present invention are a frequency offset estimation method and apparatus for a wireless signal, a node, a device and a storage medium, the method comprising: obtaining a first estimated frequency offset according to a peak frequency of a frequency domain power spectrum of an M power of a burst signal of a received baseband signal, the first estimated frequency offset being one-M of the peak frequency, the burst signal comprises a BPSK (Binary Phase Shift Keying) modulated synchronization sequence with a first length and an MPSK (Maximum Phase Shift Keying) modulated data sequence with a second length during transmission; when the absolute value of the first estimation frequency offset is greater than or equal to the difference value between one-M of the sampling frequency of the baseband signal and the maximum frequency offset, the first estimation frequency offset is corrected by obtaining a second estimation frequency offset according to the peak frequency of the frequency d
