A method performed by a communication network node is provided for scheduling of a User Equipment, UE, in a communication network which comprises the UE and the communication network node. The UE is arranged to communicate data on a plurality of bearers with the communication network node. In the method, one or more active bearers among the plurality of bearers are determined, the highest priority of the active bearers are determined, and a data transmission in uplink is scheduled for the UE based on the highest priority. By only taking active bearers in account when scheduling, UEs with non-active high priority bearer are prevented from performing free-riding traffic on lower prioritized bearers.
