1. An information transmission method, comprising:
determining, by a transmitting node, a reference signal for positioning and transmitting configuration information of the reference signal for positioning to a positioning server, wherein the reference signal for positioning at least comprises a Positioning Reference Signal (PRS); and
transmitting, by the transmitting node, the reference signal according to the configuration information,
wherein the reference signal for positioning further comprises a supplementary reference signal, and
wherein the configuration information comprises configuration information of the supplementary reference signal resource collection, and the step of determining, by the transmitting node, the reference signal for positioning and transmitting the configuration information of the reference signal for positioning to the positioning server comprises:
using, by the transmitting node, in a muting configuration period, a reference signal set, which satisfies a positioning requirement and a time difference between which and a muted PRS period is smaller than a preset threshold, as the supplementary reference signal; and
transmitting, by the transmitting node, configuration information of a supplementary reference signal resource collection to the positioning server.
