| 发明名称 | Method for measuring position in wireless communication system | ||
| 摘要 | 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. | ||

| 主权项 | 1. 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. | ||
