Methods and network nodes for determining an indication of interference mitigation and for scheduling a transmission

A radio network node for scheduling a transmission from the radio network node to a user equipment, the radio network node comprising:

• a processing circuit configured to:
• obtain an indication of interference mitigation in a receiver comprised in the user equipment, wherein the indication of interference mitigation is greater than the further indication of interference mitigation obtained from a further receiver in a further user equipment, and wherein the indication is indicative of a level of interference mitigation, and;
• determine whether the indication of interference mitigation is above a first threshold value for interference mitigation;
• determine a level of interference on each of a plurality of radio resources;
• obtain, from the user equipment, a first set of measures and a second set of measures, wherein the first set of measures relates to a signal received by the user equipment and the second set of measures relates to the same signal, wherein the first set of measures is obtained by the user equipment prior to processing of the signal in the receiver, and wherein the second set of measures is obtained by the user equipment after processing of the signal in the receiver;
• determining the indication of interference mitigation based on the first set of measure and the second set of measure;
• and
• select a first set of radio resources, from amongst the plurality of radio resources, for the transmission based on the determination whether the indication of interference mitigation in the receiver is above the first threshold value and the level of interference on each of the plurality of radio resources, thereby scheduling the transmission, selecting a second set of radio resources from amongst the plurality of radio resources based on the further indication of interference mitigation, wherein the second set of radio resources comprises resources for which each of the determined interference is less than each of the determined interference of the first set of radio resources.

A method, in a radio network node, for scheduling a transmission from the radio network node to a user equipment, the method comprising:

• obtaining, by the radio network node, an indication of interference mitigation in a receiver comprised in the user equipment, wherein the indication is indicative of a level of interference mitigation, and wherein the indication of interference mitigation is greater than the further indication of interference mitigation obtained from a further receiver in a further user equipment;
• determining, by the radio network node, whether the indication of interference mitigation is above a first threshold value for interference mitigation;
• determining, by the radio network node, a level of interference on each of a plurality of radio resources;
• obtaining, from the user equipment, a first set of measures and a second set of measures, wherein the first set of measures relates to a signal received by the user equipment and the second set of measures relates to the same signal, wherein the first set of measures is obtained by the user equipment prior to processing of the signal in the receiver, and wherein the second set of measures is obtained by the user equipment after processing of the signal in the receiver;
• determining the indication of interference mitigation based on the first set of measure and the second set of measure;
• and
• selecting, by the radio network node, a first set of radio resources, from amongst the plurality of radio resources, for the transmission based on the determination whether the indication of interference mitigation in the receiver is above the first threshold value and the level of interference on each of the plurality of radio resources, thereby scheduling the transmission, selecting a second set of radio resources from amongst the plurality of radio resources based on the further indication of interference mitigation, wherein the second set of radio resources comprises resources for which each of the determined interference is less than each of the determined interference of the first set of radio resources.
