1. A relative angle-based positioning method, comprising:
exchanging, by a network device participating in positioning, an uplink positioning configuration with a positioning center, a terminal device, and a serving cell that participate in positioning;
receiving, by the network device participating in positioning, a first reference signal sent by the terminal device;
determining, by the network device participating in positioning, angle measurement information based on the first reference signal, wherein the angle measurement information comprises a set reference direction and an angle of a direction of the terminal device relative to the set reference direction; and
reporting, by the network device participating in positioning, the angle measurement information to the positioning center;
wherein a setting manner of the set reference direction comprises one or more of:
an orientation of an antenna linear array of the network device participating in positioning;
an orientation of a horizontal dimension of an antenna planar array of the network device participating in positioning; or
a direction randomly selected by the network device participating in positioning.
