Abstract
According to one embodiment of the present specification, provided is a method for measuring a position in a wireless communication system. The method for measuring a position comprises the steps of: receiving observed time difference of arrival (OTDOA) assistance data from a positioning server; increasing an FFT sampling size when the value of a bandwidth of a positioning reference signal (PRS) included in the OTDOA assistance data is less than a first value; processing a plurality of received PRSs through the increased FFT sampling size; and calculating a reference signal time difference (RSTD) between the plurality of received PRSs.
Claims9
A method of measuring a position in a wireless communication system, the method comprising:
- receiving observed time difference of arrival (OTDOA) assistance data from a location server;
- comparing a bandwidth of a positioning reference signal (PRS) included in the OTDOA assistance data with a specific bandwidth;
- increasing a fast Fourier transform (FFT) sampling size when the bandwidth of the PRS included in the OTDOA assistance data is narrow than the specific bandwidth;
- processing a plurality of received PRSs by using the increased FFT sampling size;
- and
- calculating a reference signal time difference (RSTD) between the plurality of received PRSs.
A terminal for performing a position in a wireless communication system, the terminal comprising:
- a radio frequency (RF) unit for receiving observed time difference of arrival (OTDOA) assistance data from a location server;
- and
- a processor configured to:
- compare a bandwidth of a positioning reference signal (PRS) included in the OTDOA assistance data with a specific bandwidth;
- increase a fast Fourier transform (FFT) sampling size when the bandwidth of the PRS included in the OTDOA assistance data is narrow than the specific bandwidth,
- process a plurality of received PRSs by using the increased FFT sampling size, and
- calculate a reference signal time difference (RSTD) between the plurality of received PRSs.
