1. A positioning reference signal (PRS) generation method, comprising:
generating a positioning frequency domain sequence according to time-frequency resource information and system configuration information, wherein the time-frequency resource information comprises a number Nprsslot of allocated system symbols consecutive in time, and the system configuration information comprises positioning subcarrier spacing Δfprs; and
generating, based on the positioning frequency domain sequence, positioning time domain data consecutive in a time period of the Nprsslot consecutive system symbols;
wherein a length of the positioning frequency domain sequence is equal to 2λ*a number of system subcarriers of an allocated frequency domain resource, wherein λ is a natural number.
