Abstract
The present disclosure provides a terminal positioning method and apparatus. The method comprises: obtaining beam information corresponding to a terminal; obtaining a time advance amount of the terminal in a serving cell; and determining location information of the terminal according to the beam information and the time advance amount. The present disclosure may solve the technical problem of low terminal positioning precision.
Claims19
A terminal positioning method, applied to a transmission device, comprising:
- obtaining beam information corresponding to a terminal;
- obtaining a time advance amount of the terminal in a serving cell;
- and
- determining location information of the terminal according to the beam information and the time advance amount;
- wherein said determining location information of the terminal according to the beam information and the time advance amount comprising:
- determining a beam scheduled for the terminal according to the beam information;
- and
- determining the location information of the terminal according to the determined beam and the time advance amount;
- and
- determining the location information of the terminal according to the determined beam and the time advance amount through a preset polarization coordinate system,
- wherein the preset polarization coordinate system is a polarization coordinate system generated by using the transmission device as a circle center and using a preset direction as a polar axis.
A terminal positioning method, applied to a terminal, comprising:
- obtaining beam information;
- and
- sending the beam information to a transmission device, so that the transmission device determines location information of the terminal according to the beam information and a time advance amount after obtaining the time advance amount of the terminal in a serving cell;
- wherein said obtaining beam information comprises:
- detecting the signal strength of measurement signals on different beams of the transmission device;
- and
- obtaining the beam information according to the signal strength;
- wherein the beam information comprising first identification information of a first beam, and the first beam is a beam whose signal strength is greater than or equal to a first preset strength threshold among the different beams;
- said obtaining the beam information according to the signal strength comprising:
- determining the first beam whose signal strength is greater than or equal to the first preset strength threshold;
- and
- generating the beam information according to the first identification information of the first beam;
- and
- said sending the beam information to a transmission device comprising:
- sending the first identification information of the first beam to the transmission device, so that the transmission device determines an analog beam scheduled for the terminal according to the first identification information of the first beam.
