Abstract
A method performed by a first network node (110) for determining a synchronized time reference in a wireless communications network (100) is provided. The first network node (110) determine a first timing reference (t3) by detecting a broadcasted time reference signal (S1). Also, the first network node (110) receive information indicating a first timing difference (Δt21−22) between a second timing reference (t21) that is based on a detection of the broadcasted time reference signal (S1) at a second network node (111) and a third timing reference (t22) that is based on a positioning signal (S2) received by the second network node (111). Then, the first network node (110) determine a time reference for the first network node (110) based on the determined first timing reference (t3) and the received first timing difference (Δt21−22). A first network node (110) for determining a timing reference in a wireless communications network (100) is also provided. Furthermore, a second network node (111) and a method performed therein for enabling a synchronized time reference in a wireless communications network (100) are also provided.
