Abstract: A method performed by a network node for handling channel feature estimates associated with a radio channel between a User Equipment, UE, and the network node in a wireless communications network is provided. The network node obtains a channel feature estimates associated to the radio channel estimated at a first point in time. Data representing the channel feature estimates has a first size. The network node compresses the channel feature estimates at the first point in time by replacing them with updated channel feature estimates that at the subsequent point in time fulfils a respective threshold condition. The data representing the updated channel feature estimates has a second size. The second size is smaller than the first size. The network node then adjusts parameters for a transmission at the radio channel based on the updated channel feature estimates.
