Abstract
A method performed by a network node for performing Congestion Control in a wireless communications network is provided. The network node serves a number of User Equipments, UEs, comprising a first and one or more second UEs. The first UE has a radio resource allocated for communication between the first UE and the network node. The network node estimates (203) a first prediction of a forthcoming usage of the allocated radio resource, based on a measured data traffic between the network node and the first UE. The network node further determines (205) a first threshold related to the first prediction, as a function of a measured data traffic load between the network node and the number of UEs. The network node then performs (206) congestion control by deciding whether or not to initiate a removal of the radio resource allocated to the first UE, based on whether or not the first prediction exceeds the first threshold.
