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

Abstract

A method performed by a first network node () for determining a synchronized time reference in a wireless communications network () is provided. The first network node () determine a first timing reference (t) by detecting a broadcasted time reference signal (S). Also, the first network node () receive information indicating a first timing difference (Δt) between a second timing reference (t) that is based on a detection of the broadcasted time reference signal (S) at a second network node () and a third timing reference (t) that is based on a positioning signal (S) received by the second network node (). Then, the first network node () determine a time reference for the first network node () based on the determined first timing reference (t) and the received first timing difference (Δt). A first network node () for determining a timing reference in a wireless communications network () is also provided. Furthermore, a second network node () and a method performed therein for enabling a synchronized time reference in a wireless communications network () are also provided.
