FREQUENCY SWEEPING METHOD, DEVICE AND TERMINAL, AND COMPUTER STORAGE MEDIUM

Disclosed in an embodiment of the present invention is a frequency sweeping method, comprising: acquiring an initial primary synchronization signal (PSS) peak envelope of a frequency band that requires frequency sweeping; when the initial PSS peak envelope satisfies a set condition, determining a frequency subband a center point of which is a frequency point corresponding to a maximum peak of the initial PSS peak envelope; or, acquiring the i-th PSS peak envelope of the frequency band that requires frequency sweeping, where i is greater than 1, and when the i-th PSS peak envelope of the frequency band that requires frequency sweeping satisfies the set condition, determining a frequency subband a center point of which is a frequency point corresponding to a maximum peak of a current PSS peak envelope; and determining a frequency point of the frequency sweeping result in the frequency subband. Also disclosed in embodiments of the present invention are a frequency sweeping device and terminal, and a computer sto
