Abstract
A beam fingerprint-based positioning method, performed by a communication node located in a target space, may include: performing measurements on positioning signals transmitted from at least one reference node through a plurality of directional beams in a beam sweeping scheme; transmitting a result of the measurements to a central node; and receiving information on a position of the communication node from the central node.
Claims17
A beam fingerprint-based positioning method, performed by a communication node located in a target space, the beam fingerprint-based positioning method comprising:
- performing measurements on positioning signals transmitted from at least one reference node through a plurality of directional beams in a beam sweeping scheme;
- transmitting a result of the measurements to a central node;
- and
- receiving information on a position of the communication node from the central node,
- wherein the central node selects at least one beam least affected by an environmental change among the plurality of directional beams by inputting the received result of the measurements to learning models each of which is generated for each of the plurality of directional beams at each of a plurality of reference positions existing in the target space, and determines an estimated position of the communication node based on learning models for reference positions for the selected at least one beam and the received result of the measurements.
A beam fingerprint-based positioning method, performed by a central node for positioning in a target space, the beam fingerprint-based positioning method comprising:
- receiving, from a communication node, a result of measurements on positioning signals transmitted from at least one reference node through a plurality of directional beams in a beam sweeping scheme;
- determining a position of the communication node based on the result of the measurements;
- and
- transmitting information on the position of the communication node to the communication node,
- wherein the determining of the position comprises:
- selecting at least one beam least affected by an environmental change among the plurality of directional beams by inputting the received result of the measurements to learning models each of which is generated for each of the plurality of directional beams at each of a plurality of reference positions existing in the target space;
- and
- determining an estimated position of the communication node based on learning models for reference positions for the selected at least one beam and the received result of the measurements.
A communication node located in a target space, the communication node comprising:
- a processor;
- a memory electronically communicating with the processor;
- and
- instructions stored in the memory,
- wherein when executed by the processor, the instructions cause the communication node to:
- perform measurements on positioning signals transmitted from at least one reference node through a plurality of directional beams in a beam sweeping scheme;
- transmit a result of the measurements to a central node;
- and
- receive information on a position of the communication node from the central node,
- wherein the central node selects at least one beam least affected by an environmental change among the plurality of directional beams by inputting the received result of the measurements to learning models each of which is generated for each of the plurality of directional beams at each of a plurality of reference positions existing in the target space, and determines an estimated position of the communication node based on learning models for reference positions for the selected at least one beam and the received result of the measurements.
