Abstract
A method performed by a network node (110) in a wireless communications network (100) for enabling a timing reference in a second wireless device (122) for use in Sidelink, SL, transmissions over a SL communication link (133) with a first wireless device (121) is provided. The network node estimates (201) a propagation delay of SL transmissions over the SL communication link (133) between the first and second wireless device (122). Then, the network node (110) transmits, to the second wireless device (122), timing reference information based on a timing reference originating from a time reference node in a wireless communications network (100), and on the estimated propagation delay of SL transmissions over the SL communication link (133) between the first and second wireless device (122). A network node (110) for enabling a timing reference in a second wireless device (122) for use in SL transmissions over a SL communication link (133) with a first wireless device (121) is also provided. A first wireless (121), a second wireless device (122) and methods therein are also provided, as well as, computer programs and carriers.
