RECONFIGURABLE ANTENNA-BASED POSITIONING METHOD AND SYSTEM

摘要

A reconfigurable antenna-based positioning method and system. The method comprises: a first antenna transmits a plurality of first beams to the surroundings, and scans, by means of the plurality of first beams, for uplink signals transmitted by a UE to obtain a first incident angle from the first antenna to the UE (S21); the first antenna transmits a plurality of second beams to the surroundings, the scanning angle for each second beam is smaller than that for each first beam, and scans, by means of the second beams, for uplink signals transmitted by the UE within the first incident angle to obtain a second incident angle from the first antenna to the UE (S22); the first antenna and two second antennas located at different positions simultaneously transmit downlink signals to the UE, and obtains time or a difference in time of arrivals of the downlink signals at the UE (S23); position the UE according to the second incident angle and the time or the difference in time (S24).
