A method performed by a first network node for uplink congestion control in a radio network is provided. The first network node is operable to handle one or more first layers of a protocol stack for an uplink connection between a wireless device and the radio network and is communicatively coupled to a second network node handling one or more second, lower layers of the protocol stack. The method comprises obtaining an indication of a proportion of packets within an uplink user plane flow that are to be marked with a congestion indicator, in which the proportion is based on a delay experienced by packets of the uplink user plane flow sent by the wireless device to the second network node. The method further comprises marking the proportion of packets with the congestion indicator and transmitting packets for the uplink user plane flow towards a core network of the radio network.
A method performed by a first network node for uplink congestion control in a radio network, the first network node handling one or more first layers of a protocol stack, including a packet data convergence protocol (PDCP) layer, for an uplink connection between a wireless device and the radio network, the first network node being communicatively coupled to a second network node handling one or more second layers of the protocol stack for the uplink connection, wherein the one or more second layers are lower than the one or more first layers, the method comprising:
