1. A method, the method comprising:
for a first positioning reference node (PRN) included in a set of P positioning reference nodes, where P>2, determining a first set of candidate positions to which the first PRN can move;
for each candidate position included in the first set of candidate positions, evaluating an objective function using the candidate position, the position of each other PRN included in the set of P PRNs, and the position of a target UE to produce an error value indicating a positioning error of the target UE for the candidate position; and
based on the produced error values, selecting a candidate position from the set of candidate positions.
