1. A network node for enabling a timing reference in a second wireless device for use in Sidelink (SL) transmissions over a SL communication link with a first wireless device, the network node comprising:
processing circuitry configured to:
estimate a propagation delay of SL transmissions over the SL communication link between the first and second wireless device; and
transmit, to the second wireless device, timing reference information based on a timing reference originating from a time reference node in a wireless communications network, and on the estimated propagation delay of SL transmissions over the SL communication link between the first and second wireless device.
