A network node operable in a wireless communications system supporting direct communication between user equipments, comprising:

• a storage with a sidelink configuration stored per user equipment and specifying a plurality of destination groups, each destination group including possible destinations for sidelink data as well as storing a logical channel priority for each logical channel out of logical channels configured for the sidelink destination groups;
• and
• a scheduling unit that:
• selects a sidelink destination group with a sidelink logical channel having sidelink data available for transmission with the highest logical channel priority among the sidelink logical channels having data available for transmission;
• and
• allocates radio resources to the user equipment in the selected sidelink destination group accordingly.
