Electronic device and method for positioning

An electronic device used with a user equipment (UE), the electronic device comprising:

• at least one processor;
• and
• at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the electronic device to:
• receive a set of first reflected beams reflected from a first set of intelligent surfaces to perform a first beam scanning;
• receive a set of second reflected beams reflected from a second set of intelligent surfaces to perform a second beam scanning, wherein the second set of intelligent surfaces is selected from the first set of intelligent surfaces, and a beam width for the set of second reflected beams is smaller than a beam width for the set of first reflected beams;
• and
• acquire a position of the UE that is determined based at least in part on a result of the second beam scanning.

A method performed by an electronic device on a base station side, comprising:

• causing a first set of intelligent surfaces to reflect a set of first reflected beams to be used for a first beam scanning with a user equipment (UE);
• causing a second set of intelligent surfaces to reflect a set of second reflected beams to be used for a second beam scanning with the UE, wherein the second set of intelligent surfaces is selected from the first set of intelligent surfaces, and a beam width for the set of second reflected beams is smaller than a beam width for the set of first reflected beams;
• and
• determining a position of the UE, based at least in part on a result of the second beam scanning.

A method performed by an electronic device on a user equipment (UE) side, comprising:

• receiving a set of second reflected beams reflected from a second set of intelligent surfaces to perform a second beam scanning, wherein the second set of intelligent surfaces is selected from the first set of intelligent surfaces, and a beam width for the set of second reflected beams is smaller than a beam width for the set of first reflected beams;
• and
• acquiring a position of the UE that is determined based at least in part on a result of the second beam scanning.
