Improved techniques of acquiring A-GNSS data include enabling a terminal UE (T-UE) that is out-of-coverage (OOC) in a 5G NR network to obtain A-GNSS data from an aid UE (A-UE) that is in-coverage in the 5G NR network, the A-UE being configured to access the A-GNSS data from a network node and to provide assistance to a T-UE, and the T- UE being configured to broadcast, via a sidelink connection, a request to obtain A-GNSS data.
