Apparatuses, methods, and systems are disclosed for supporting power saving for V2X communications. One apparatus includes a transceiver and a processor that receives a first request from a first application to send data over a PC5 interface. The processor determines a first PC5 DRX configuration for the first application based on at least one first QoS requirement and determines to establish a first PC5 QoS Flow to transmit the data. The processor associates the first PC5 DRX configuration with the first PC5 QoS Flow and sends a second request to an AS layer to establish a first QoS Flow, where the second request indicates a first QoS parameter and the first PC5 DRX configuration.

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.
