Abstract
A method by a Mobile Terminal (MT) for positioning the MT is provided. The method includes requesting a Base Station (BS) to allocate a first transmission time for transmitting a first sounding signal for the MT, receiving the first transmission time from the BS, transmitting the first sounding signal to the BS at the first transmission time, requesting the BS to allocate a second transmission time of a second sounding signal for the MT after the MT moves, receiving the second transmission time from the BS, transmitting the second sounding signal to the BS at the second transmission time, reporting a moving distance moved during the period between the first transmission time and the second transmission time, and receiving a position of the MT determined based on the first sounding signal, the second sounding signal, and the moving distance.
