Abstract: Provided are a positioning reference signal (PRS) transmission method and apparatus, and a storage medium. A PRS sending end presets PRS blocks having the same number as the number of shaped beams, a corresponding PRS sequence in each PRS block by using a preset sequence generation rule, and each PRS block containing the corresponding PRS sequence is sent according to a preset sending order of the PRS blocks in a polling manner through a shaped beam corresponding to the each PRS block. A PRS receiving end acquires a first PRS block sent by the PRS sending end; and when the first PRS block contains a block index, a sending index of a shaped beam corresponding to the first PRS block corresponding to the block index is determined according to preset correspondence; or when the first PRS block contains no block index, a sending index of a shaped beam corresponding to the first PRS block is determined according to a preset calculation rule. The sending index of the shaped beam is used for determining a time-domain position of the shaped beam.
