Embodiments include methods for a user equipment (UE) to obtain positioning assistance data associated with a cell of a wireless network. Such methods include receiving a first part of the positioning assistance data associated with the cell from a positioning node via unicast in the cell, and receiving a second part of the positioning assistance data associated with the cell via system information (SI) broadcast in the cell. Such methods also include, based on the second part, determining a persistence indicator associated with the first part, and based on the persistence indicator, selectively requesting an updated first part associated with the cell from a network node of the wireless network. Other embodiments include complementary methods for a positioning node as well as UEs and positioning nodes configured to perform such methods.
