determine information for potential causes of error for one or more of a UWB configuration and a position estimate for the UE;

transmit the determined information for the potential causes of error; and

receive UWB-specific error information associated with one or more of the UWB configuration and the position estimate information for correcting the potential causes of error.

2 . The UE of claim 1 , wherein the at least one processor is configured to cause the UE to receive the UWB assistance data in a dedicated manner using long-term evolution positioning protocol (“LPP”) signaling.

3 . The UE of claim 1 , wherein the at least one processor is configured to cause the UE to receive the UWB assistance data in a broadcast signal as part of positioning system information blocks (“posSIBs”) triggered by one or more of a location server and a base station.

4 . The UE of claim 3 , wherein the at least one processor is configured to cause the UE to receive the UWB assistance data in a broadcast signal as part of positioning system information blocks (“posSIBs”) in response to an on-demand posSIB request.

5 . The UE of claim 1 , wherein the UWB assistance data comprises UWB channel assignment information, anchor node identifiers, anchor node location information, or a combination thereof.

6 . The UE of claim 1 , wherein the at least one processor is configured to cause the UE to indicate a type of UWB positioning method utilized to compute location information, wherein transmission of the location information comprises two-way ranging, phase difference of arrival, time difference of arrival, or a combination thereof.

7 . The UE of claim 1 , wherein the location information comprises absolute and relative location data, latitude points, longitude points, horizontal and vertical velocity estimates, positioning and velocity uncertainty values, positioning error, heading information, 3D location estimates, elevation information, integrity of positioning estimates, quality of positioning estimate metrics, or a combination thereof.

8 . The UE of claim 1 , wherein the at least one processor is configured to cause the UE to receive a positioning mode for UWB radio access technology (“RAT”)-independent positioning, the positioning mode comprising a standalone mode, UE-assisted mode, UE-based mode, sidelink-based positioning mode, or a combination thereof.

9 . The UE of claim 8 , wherein the at least one processor is configured to cause the UE to transmit ranging measurements according to the positioning mode, wherein supported ranging measurements comprise a timestamp, ranging counter, ranging offset, angle-of-arrival support indication, angle-of-arrival azimuth, angle-of-arrival elevation, received signal strength indicator, or a combination thereof.

10 . The UE of claim 1 , wherein the at least one processor is configured to cause the UE to determine absolute positioning, relative positioning, velocity estimates, or a combination thereof for the UE based on the UWB positioning method.

11 . The UE of claim 1 , wherein the at least one processor is configured to cause the UE to enhance location and tracking accuracy of the UE by combining the UWB positioning method, at least one or more combinations of RAT-dependent positioning methods, and other RAT-independent positioning methods.

12 . The UE of claim 1 , wherein the at least one processor is configured to cause the UE to transmit an error type indication, the error type indication determined according to whether a cause of the error originates at the UE or a location server.

13 . The UE of claim 1 , wherein the at least one processor is configured to cause the UE to utilize a Uu interface between the UE and a base station, and a sidelink interface between the UE and a peer UE for transmitting and receiving information related to the UWB positioning method.

14 . A method performed by a user equipment (“UE”), the method comprising:

transmitting a set of capabilities related to ultra-wideband (“UWB”) positioning for the UE, the set of capabilities used to determine at least one UWB positioning method for performing UWB positioning of the UE;
