Method and arrangements for supporting serving of multiple wireless devices based on prediction of radio channel estimation accuracy degredation

A method, performed by one or more network nodes, for supporting serving of multiple wireless devices by a radio network node of a wireless communication network, said serving to be performed using Time Division Duplex, TDD, over a frequency carrier, and wherein the radio network node is configured to, for each of said wireless devices, estimate a downlink radio channel of a wireless device based on reference signals transmitted by the wireless device in TDD uplink slots with TDD downlink slots therebetween, wherein the method comprises:

• obtaining channel estimation accuracy degradation information for at least one of said multiple wireless devices, wherein said channel estimation accuracy degradation information for respective one of said at least one wireless devices indicates a prediction of a degradation of radio channel estimation accuracy for this wireless device during TDD downlink slots;
• and
• performing scheduling of said multiple wireless devices in said TDD downlink slots based on the obtained channel estimation accuracy degradation information, such that when the predicted degradation of radio channel estimation accuracy is greater for a wireless device among said wireless devices, greater influence is applied for scheduling the wireless device early among said TDD downlink slots.
