A method for determining first channel state information predicted for an upcoming time slot, said first channel state information being for use by a first radio network node (Na) when determining a set of radio transmission parameters for a first transmission in said upcoming time slot between the first radio network node (Na) and a first user equipment (UEa) being served by the first radio network node (Na), wherein the method is performed by a network node which is either the first radio network node (Na) or a network node controlling the first radio network node and/or controlling a second radio network node (Nb) and wherein the method is characterized by: receiving a report of predicted transmission, the report being received from the second radio network node (Nb), wherein the report of predicted transmission comprises information about a second transmission, predicted for the upcoming time slot, to the second radio network node (Nb) from a second user equipment (UEb) being served by the second radio network node (Nb), wherein said second transmission in said upcoming time slot is to interfere with said first transmission in said upcoming time slot; and when the first transmission and the second transmission in said upcoming time slot are both uplink transmissions, the method comprises: performing a first estimation on a channel over which another transmission in a time slot preceding the upcoming time slot from the second user equipment (UEb) to the second radio network node (Nb) is received by the first radio network node (Na), and determining second channel state information as a prediction of interference for the upcoming time slot based on the first estimation and on the report of predicted transmission; performing a second estimation on a channel over which another transmission in another time slot preceding the upcoming time slot from the first user equipment (UEa) to the first radio network node (Na) is received by the first radio network node (Na), and determining third channel state estimation as a prediction of channel state information for the upcoming time slot based on the second estimation; and determining the first channel state information, predicted for said upcoming time slot, based on the second channel state information and the third channel state information by combining the second and third channel state information. performing a first estimation on a channel over which another transmission in a time slot preceding the upcoming time slot from the second user equipment (UEb) to the second radio network node (Nb) is received by the first radio network node (Na), and determining second channel state information as a prediction of interference for the upcoming time slot based on the first estimation and on the report of predicted transmission; performing a second estimation on a channel over which another transmission in another time slot preceding the upcoming time slot from the first user equipment (UEa) to the first radio network node (Na) is received by the first radio network node (Na), and determining third channel state estimation as a prediction of channel state information for the upcoming time slot based on the second estimation; and determining the first channel state information, predicted for said upcoming time slot, based on the second channel state information and the third channel state information by combining the second and third channel state information.
