METHOD AND APPARATUS FOR POSITIONING MOBILE TERMINAL'S LOCATION
First Claim
1. A method by a Mobile Terminal (MT) for positioning the MT, the method comprising:
- 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 to allocate a second transmission time of a second sounding signal for the MT to the BS again 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 by using the first sounding signal, the second sounding signal, and the moving distance.

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.

5. A method by a Base Station (BS) for positioning a Mobile Terminal (MT), the method comprising:
-
transmitting a first transmission time of a first sounding signal for the MT to the MT; receiving the first sounding signal transmitted from the MT at the first transmission time; recording a first arrival time of the first sounding signal and an Angle Of Arrival (AOA) of the first sounding signal; transmitting a second transmission time of a second sounding signal for the MT to the MT; receiving the second sounding signal transmitted from the MT at the second transmission time; recording a second arrival time of the second sounding signal and an AOA of the second sounding signal; receiving from the MT a moving distance moved by the MT during the period between the first transmission time and the second transmission time; and positioning the MT based on the first arrival time, the AOA of the first sounding signal, the second arrival time, the AOA of the second sounding signal, and the moving distance. - View Dependent Claims (6, 8, 15, 16, 17)

9. A Mobile Terminal (MT) for positioning in a communication system, the MT comprising:
-
a transmitter for transmitting a request to a Base Station (BS) to allocate a first transmission time, for transmitting a first sounding signal for the MT, for transmitting the first sounding signal at the first transmission time to the BS, for transmitting a request to the BS to allocate a second transmission time of a second sounding signal for the MT after the MT moves, for transmitting the second sounding signal at the second transmission time to the BS, and for reporting a moving distance moved during the period between the first transmission time and the second transmission time; and a receiver for receiving the first transmission time and the second transmission time from the BS, and for receiving a positioning result of the MT determined based on the first sounding signal, the second sounding signal, and the moving distance. - View Dependent Claims (10, 11, 18)
