Claim 15:
16. A method for a second radio access network (RAN) node used in a radio communication system that supports a first Radio Access Technology (RAT) and a second RAT, the second RAN node being associated with the second RAT, the method comprising:
notifying a first RAN node associated with the first RAT of a first numerology that is included in multiple numerologies, in a setup procedure of an inter-RAN node interface between the first RAN node and the second RAN node; and
sending a radio resource configuration of the second RAT to a radio terminal via the first RAN node, wherein
the radio resource configuration explicitly or implicitly indicates at least one second numerology,
the first numerology corresponds to numerology of Synchronization Signal, and
the at least one second numerology corresponds to numerology of other channels than Synchronization Signal.
