Embodiments herein relate to a method in a positioning node for enabling positioning of a user equipment, which user equipment is served in a first cell controlled by a radio network node. The positioning node and radio network node are comprised in a radio communications network. The positioning node obtains an indication indicating availability, at the user equipment, of timing information of at least one cell. The positioning node further determines whether the timing information of the at least one cell is available at the user equipment based on the obtained indication, which timing information is enabling positioning of the user equipment.
