Claim 0:
1. A method performed by a first radio node for mitigating interference between two or more three-dimensional, 3D, beams between the first radio node and one or more other radio nodes, the method comprising:
performing an initial beam establishment procedure to determine a plurality of beam pairs between the first radio node and one or more other radio nodes, the plurality of beam pairs comprising:
a first beam pair between the first radio node and a second radio node, the first beam pair comprising a first transmit beam for signal transmission from the first radio node to the second radio node and a first receive beam for signal reception at the first radio node from the second radio node; and
a second beam pair between the first radio node and another radio node where the another radio node is either the second radio node or a third radio node, the second beam pair comprising a second transmit beam for signal transmission from the first radio node to the another radio node and a second receive beam for signal reception at the first radio node from the another radio node;

obtaining movement information for the first radio node, the second radio node, and the another radio node;
determining, from among the plurality of beam pairs, two or more beam pairs to be adjusted based on the movement information;
selecting, based one or more parameters, a beam pair from among the two or more beam pairs to be adjusted;
adjusting a transmit beam of the selected beam pair;
determining one or more other beams from among the plurality of beam pairs affected by the adjusted transmit beam, the adjusted transmit beam and the one or more other beams being on a same frequency;
performing a frequency switching procedure such that either the adjusted transmit beam or at least one of the one or more other beams affected by the adjusted transmit beam is switched to a different frequency; and
repeating the steps of selecting a transmit beam from among the two or more beam pairs to be adjusted, adjusting the selected transmit beam, determining one or more other beams, and performing the frequency switching procedure, for at least one additional transmit beam from among the two or more transmit beams to be adjusted.
