Abstract
An operation method of a terminal supporting observed time difference of arrival (OTDOA)-based positioning includes measuring, based on a first measurement window, a first arrival time of a first positioning reference signal (PRS) received from a serving cell, adjusting a second measurement window for measuring a second arrival time of a second PRS received from a first neighbor cell, to generate an adjusted second measurement window, measuring the second arrival time, based on the adjusted second measurement window, and generating a first reference signal timing difference (RSTD) that is a difference between the first arrival time and the second arrival time.
Claims20
An operation method of a terminal supporting observed time difference of arrival (OTDOA)-based positioning, the operation method comprising:
- measuring, based on a first measurement window, a first arrival time of a first positioning reference signal (PRS) received from a serving cell;
- adjusting a second measurement window for measuring a second arrival time of a second PRS received from a first neighbor cell, to generate an adjusted second measurement window;
- measuring the second arrival time, based on the adjusted second measurement window;
- and
- generating a first reference signal timing difference (RSTD) that is a difference between the first arrival time and the second arrival time.
A terminal supporting observed time difference of arrival (OTDOA)-based positioning, the terminal comprising:
- a radio frequency (RF) circuit configured to receive a first positioning reference signal (PRS) from a serving cell and a second PRS from a first neighbor cell;
- and
- a positioning circuit configured to:
- measure a first arrival time of the first PRS, based on a first measurement window,
- measure a second arrival time of the second PRS, based on an adjusted second measurement window that has been adjusted by adjusting a second measurement window for measuring the second arrival time of the second PRS, and
- generate a first reference signal timing difference (RSTD),
- wherein the first RSTD is a difference between the first arrival time and the second arrival time.
An operation method of a terminal supporting observed time difference of arrival (OTDOA)-based positioning, the operation method comprising:
- configuring a first measurement window for measuring a first arrival time of a first positioning reference signal (PRS) received from a serving cell;
- configuring a second measurement window for measuring a second arrival time of a second PRS received from a first neighbor cell;
- configuring a third measurement window for measuring a third arrival time of a third PRS received from a second neighbor cell;
- and
- adjusting at least one of the second measurement window, based on the first measurement window to generate an adjusted second measurement window or the third measurement window, based on the first measurement window, to generate an adjusted third measurement window.
