Nodes and methods for determining and enabling a synchronized time reference in a wireless communications network

A method performed by a first network node for determining a synchronized time reference in a wireless communications network, the method comprising:

• determining a first timing reference by detecting a broadcasted time reference signal transmitted from a transmitter of a LORAN-C, eLORAN, DCF77, or Chayka system;
• receiving information indicating a first timing difference and at least a second timing difference, wherein the first timing difference is between a second timing reference that is based on a detection of the broadcasted time reference signal at a second network node and a third timing reference that is based on a positioning signal received by the second network node, and the second timing difference is between at least a fourth timing reference determined by at least a third network node by detecting the broadcasted time reference signal at the at least third network node, and at least a fifth timing reference based on the positioning signal received by the at least third network node;
• and
• determining a synchronized time reference for the first network node based on the determined first timing reference and a third timing difference, wherein the third timing difference is determined based on a weighted average of the first and the at least second timing difference indicated in the received information, wherein the weighted average is further based on corresponding distances of the second network node and the at least third network node to the first network node.
