Positioning reference signal transmission method and apparatus, device, and storage medium

A positioning reference signal (PRS) transmission method, applied to a PRS receiving end, comprising:

• acquiring a first PRS block sent by a PRS sending end;
• and
• in a case where the first PRS block contains a block index, determining a sending index of a shaped beam corresponding to the first PRS block corresponding to the block index according to preset correspondence;
• or
• in a case where the first PRS block contains no block index, determining a sending index of a shaped beam corresponding to the first PRS block according to a preset calculation rule;
• wherein the sending index of the shaped beam is used for determining a time-domain position of the shaped beam.

A positioning reference signal (PRS) transmission apparatus, configured on a PRS sending end, comprising:

• a setting module and a sending module, wherein
• the setting module is configured to preset PRS blocks having a same number as a number of shaped beams, and set a corresponding PRS sequence in each of the PRS blocks by using a preset sequence generation rule;
• and
• the sending module is configured to send, through a shaped beam corresponding to each of the PRS blocks, the each of the PRS blocks containing the corresponding PRS sequence in a polling manner according to a preset sending order of the PRS blocks.
