Abstract

Presented are systems and methods for positioning. A method includes sending, by a core network entity to a first wireless communication entity, a first message including measurement and/or assistance data for positioning, wherein the assistance data includes no or one or more characteristic parameters associated with a model of an error source. Another method includes receiving, by a core network entity from a second wireless communication entity, a second message including assistance data for positioning, wherein the assistance data includes one or more characteristic parameters associated with a model of an error source.

Claims (38)

1 . A wireless communication method, comprising:

receiving, by a first wireless communication entity from a core network entity, a first message including assistance data for positioning,

wherein the assistance data includes one or more characteristic parameters associated with a model of an error source,

wherein the error source is associated with one or more location-related error sources including at least one of a transmission reception point (TRP) location or an antenna reception point (ARP) location, and

wherein the error source is associated with a standard deviation having an integer value in a range from 0 to 31, and a resolution of m1, m10 or m30.

2 . The wireless communication method of claim 1 , wherein the model of the error source includes an overbounding model, and the one or more characteristic parameters include a standard deviation.

3 . The wireless communication method of claim 1 , wherein the error source is associated with one or more timing-related errors, and

wherein the error source includes an inter-TRP synchronization.

4 . The wireless communication method of claim 1 , wherein the error source is associated with a normal distribution.

5 . A wireless communication method, comprising:

sending, by a core network entity to a first wireless communication entity, a first message including assistance data for positioning,

wherein the assistance data includes one or more characteristic parameters associated with a model of an error source,

wherein the error source is associated with one or more location-related error sources including at least one of a transmission reception point (TRP) location or an antenna reception point (ARP) location, and

wherein the error source is associated with a standard deviation having an integer value in a range from 0 to 31, and a resolution of m1, m10 or m30.

6 . The wireless communication method of claim 5 , wherein the model of the error source includes an overbounding model, and the one or more characteristic parameters include a standard deviation.

7 . The wireless communication method of claim 5 , further comprising:

identifying, by the core network entity, the error source associated with one or more timing-related errors,

wherein the error source includes an inter-TRP synchronization.

8 . The wireless communication method of claim 5 , wherein the error source is associated with a normal distribution.

9 . A first wireless communication entity, comprising:

a receiver configured to receive, from a core network entity, a first message including assistance data for positioning,

wherein the assistance data includes one or more characteristic parameters associated with a model of an error source,

wherein the error source is associated with one or more location-related error sources including at least one of a transmission reception point (TRP) location or an antenna reception point (ARP) location, and

wherein the error source is associated with a standard deviation having an integer value in a range from 0 to 31, and a resolution of m1, m10 or m30.

10 . The first wireless communication entity of claim 9 , wherein the model of the error source includes an overbounding model, and the one or more characteristic parameters include a standard deviation.

11 . The first wireless communication entity of claim 9 , wherein the error source is associated with a normal distribution.

12 . The first wireless communication entity of claim 9 , wherein the error source is associated with one or more timing-related errors, and

wherein the error source includes an inter-TRP synchronization.

13 . A core network entity, comprising:

a transmitter configured to send, to a first wireless communication entity, a first message including assistance data for positioning,

wherein the assistance data includes one or more characteristic parameters associated with a model of an error source,

wherein the error source is associated with one or more location-related error sources including at least one of a transmission reception point (TRP) location or an antenna reception point (ARP) location, and

wherein the error source is associated with a standard deviation having an integer value in a range from 0 to 31, and a resolution of m1, m10 or m30.

14 . The core network entity of claim 13 , wherein the model of the error source includes an overbounding model, and the one or more characteristic parameters include a standard deviation.

15 . The core network entity of claim 13 , further comprising:

at least one processor configured to identify the error source associated with one or more timing-related errors,

wherein the error source includes an inter-TRP synchronization.

16 . The core network entity of claim 13 , wherein the error source is associated with a normal distribution.
