There is provided mechanisms for performance degradation handling between a first radio access network node that operates in a first frequency band and provides network access for subscribers of a first mobile network operator and a second radio access network node that operates in a second frequency band and provides network access for subscribers of a second mobile network operator. A method is performed by the first radio access network node. The method comprises identifying performance degradation impacting the network access for the subscribers of the first mobile network operator. The performance degradation is identified as originating from a particular direction relative the first radio access network node and as caused by the second radio access network node. The method comprises providing, towards the second radio access network node, an indication of the performance degradation. The indication specifies the particular direction and identifies the second radio access network node as causing the performance degradation.
