Abstract
The position of User Equipment (UE) may be determined based on information communicated through direct UE-to-UE communications to obtain additional measurements of position metrics that can be used to determine relative or absolute positions of the UE. In one implementation, a UE may receive, via a direct connection with a second UE, a positioning reference signal from which timing information, relating to distance between the UE and second UE, is derivable; determine, based on the positioning reference signal, a first position metric that relates to a position of the UE with respect to the second UE; and determine, based at least on position metric, a location of the UE.
