The invention relates to a first communication device arranged to provide congestion indications to a second communication device. The first communication device comprises a control unit arranged to determine to apply an indicating congestion mechanism on a first radio bearer to the second communication device based on a quality of service setting of the first radio bearer. The control unit is further arranged to set a congestion threshold value and a first drop threshold value of a packet buffer associated to the first determined radio bearer. The congestion threshold value indicates that when buffered packets in the packet buffer exceeds the set congestion threshold value the control unit is arranged further to transmit over a transmitting arrangement at least one congestion indication to the second communication device. The first drop threshold value indicates a level of the packet buffer that when buffered packets exceeds the first drop threshold value the control unit is arranged to drop at least one packet.
