The present invention relates to selection of synchronization source among various synchronization sources which include sources determining the synchronization signal from the network such as base stations (network nodes) or user equipments which receive the synchronization signal possibly over other hops from the base station, and which further includes sources which do not determine their synchronization signal from the network. The selection of the synchronization source is performed by choosing the source with the most reliable synchronization signal based on a metric calculated for each of the sources considered. In particular, the metric is based on the type of the source, number of hops between the network and the source and/or received signal quality. After selecting the source, the timing of the device is adapted accordingly.
