1. A first network node of a first radio access technology, RAT, configured to communicate with a second network node of a second RAT different from the first RAT, the first network node comprising processing circuitry configured to:
schedule a physical resource block, PRB, in a predetermined frequency carrier range, the scheduling starting from a predefined frequency location in the predetermined frequency carrier range;
receive an indication that the PRB has been scheduled by the second network node; and
responsive to the received indication, discard the PRB scheduled by the first network node if the PRB is located outside of a first predetermined partition of radio resources allocated to the first network node.
