DEVICE AND METHOD OF ESTIMATING LOCATION OF TERMINAL USING SEQUENCES TRANSMITTED FROM BASE STATIONS

A terminal receives a unique sequence from each of at least two base stations, and transmits a mixture of quantized unique sequences to a serving base station. The serving base station extracts components respectively corresponding to base stations from the mixture of the quantized unique sequences,...

More Information
Summary:A terminal receives a unique sequence from each of at least two base stations, and transmits a mixture of quantized unique sequences to a serving base station. The serving base station extracts components respectively corresponding to base stations from the mixture of the quantized unique sequences, and estimates a location of a terminal based on the extracted components. The serving base station may calculate a received signal strength or a delay for each of the unique sequences received by the terminal, based on the extracted components, and estimate the location of the terminal based on the received signal strength or the delay. In addition, the terminal may estimate its own location by performing an algorithm used by the serving base station.
