Relative angle-based positioning method and apparatus

A relative angle-based positioning method, comprising:

• exchanging, by a positioning center participating in positioning, a downlink positioning configuration with a network device, a terminal device, and a serving cell that participate in positioning;
• receiving, by the positioning center, power measurement information reported by the terminal device, wherein the power measurement information comprises one or more pieces of reference signal received power and/or one or more pieces of path power that are of one or more second reference signals and that are determined by the terminal device;
• sending, by the positioning center, request location information to the network device participating in positioning, wherein the request location information comprises the power measurement information, the request location information is used to indicate the network device participating in positioning to determine the angle measurement information based on the power measurement information, and 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;
• receiving, by the positioning center, the angle measurement information reported by the network device participating in positioning;
• and
• determining, by the positioning center, a location of the terminal device based on the angle measurement information;
• 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.

A relative angle-based positioning method, comprising:

• exchanging, by a positioning center participating in positioning, an uplink positioning configuration with a network device, a terminal device, and a serving cell that participate in positioning;
• receiving, by the positioning center, angle measurement information reported by the network device participating in positioning, wherein the angle measurement information is determined by the network device participating in positioning based on a first reference signal, the first reference signal is received by the network device participating in positioning from the terminal device, and 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
• determining, by the positioning center, a location of the terminal device based on the angle measurement information;
• 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.
