Network Node, User Equipment and Methods in a Wireless Communications Network

A method performed by a network node for handling positioning of a User Equipment (UE) in a wireless communications network, the method comprising:

• recommending configurations for multiple Transmission Reception Points (TRPs) to transmit positioning signals;
• recommending a configuration for the UE to perform respective positioning measurements of the positioning signals transmitted by the multiple TRPs;
• obtaining a position of the UE based on results of the respective positioning measurements;
• obtaining errors based on uncertainty associated with the results of the respective positioning measurement results;
• obtaining a Geometric Dilution of Precision (GDOP) for the multiple TRPs based on the obtained errors and the position of the UE;
• and
• managing transmission of the positioning signals of the multiple TRPs, based on the obtained GDOP.
