Abstract

Claims (56)

1 . A method comprising:

transmitting, by a first device to a base station, information related to a positioning group including information related to a distance between devices belonging to the positioning group;

receiving, by the first device from the base station, information related to a positioning reference signal (PRS) resource; and

transmitting or receiving, by the first device, a PRS based on the information related to the PRS resource,

wherein the PRS is a reference signal for positioning performed between a plurality of devices in the positioning group, and

wherein a number of symbols or a bandwidth of the PRS resource, allocated by the information related to the PRS resource, is configured based on the information related to the distance between the devices belonging to the positioning group.

2 . The method of claim 1 , wherein the positioning group is determined by the base station.

3 . The method of claim 1 , wherein the positioning group is determined by agreement between the first device and at least one device performing positioning with the first device.

4 . The method of claim 1 , wherein, as the distance increases, the number of symbols of the PRS resource is configured to be large.

5 . The method of claim 1 , wherein, as the distance increases, the bandwidth of the PRS resource is configured to be small.

6 . The method of claim 1 , wherein the information related to the distance includes a zone identity (ID) of the first device or information related to a maximum distance between the devices.

7 . The method of claim 1 , wherein the information related to the positioning group further includes at least one of:

ID information of the first device,

information related to a number of positioning groups to which the first device belongs, or

ID information of the positioning groups to which the first device belongs.

8 . The method of claim 1 , further comprising:

receiving, from a location server, information related to a type of positioning.

9 . The method of claim 8 ,

wherein the type of positioning includes at least one of:

Time Difference of Arrival (TDOA)-based positioning,

Round Trip Time (RTT)-based positioning,

Angle of Arrival (AoA)-based positioning,

Angle of Departure (AoD)-based positioning, or

Distributed Antenna System (DAS)-based positioning, and

wherein the information related to the PRS resource includes at least one of:

a PRS ID,

a type of the PRS resource,

a periodicity of the PRS,

a repetition number of the PRS,

information related to a time resource for the PRS, or

information related to a frequency resource for the PRS.

10 . A first device comprising:

at least one transceiver;

at least one processor; and

at least one memory connected to the at least one processor and storing instructions that, based on being executed, cause the first device to perform operations comprising:

transmitting, to a base station, information related to a positioning group including information related to a distance between devices belonging to the positioning group;

receiving, from the base station, information related to a positioning reference signal (PRS) resource; and

transmitting or receiving a PRS based on the PRS resource,

wherein the PRS is a reference signal for positioning performed between a plurality of devices in the positioning group, and

wherein a number of symbols or a bandwidth of the PRS resource, allocated by the information related to the PRS resource, is configured based on the information related to the distance between the devices belonging to the positioning group.

11 . The first device of claim 10 , wherein the positioning group is determined by the base station.

12 . The first device of claim 10 , wherein the positioning group is determined by agreement between the first device and at least one device performing positioning with the first device.

13 . The first device of claim 10 , wherein, as the distance increases, the number of symbols of the PRS resource is configured to be large.

14 . The first device of claim 10 , wherein, as the distance increases, the bandwidth of the PRS resource is configured to be small.

15 . A processing device comprising:

at least one processor; and

at least one memory connected to the at least one processor and storing instructions that, based on being executed, cause a first device to perform operations comprising:

transmitting, to a base station, information related to a positioning group including information related to a distance between devices belonging to the positioning group;

receiving, from the base station, information related to a positioning reference signal (PRS) resource; and

transmitting or receiving a PRS based on the PRS resource,

wherein the PRS is a reference signal for positioning performed between a plurality of devices in the positioning group, and

wherein a number of symbols or a bandwidth of the PRS resource, allocated by the information related to the PRS resource, is configured based on the information related to the distance between the devices belonging to the positioning group.

16 . The processing device of claim 15 , wherein the positioning group is determined by the base station.

17 . The processing device of claim 15 , wherein the positioning group is determined by agreement between the first device and at least one device performing positioning with the first device.

18 . The processing device of claim 15 , wherein, as the distance increases, the number of symbols of the PRS resource is configured to be large.

19 . The processing device of claim 15 , wherein, as the distance increases, the bandwidth of the PRS resource is configured to be small.
