Claim 17:
18. A method for a radio terminal used in a radio communication system that supports a first Radio Access Technology (RAT) and a second RAT, the method comprising:
receiving a radio resource configuration of the second RAT from a second radio access network (RAN) node associated with the second RAT via a first RAN node associated with the first RAT, wherein
a first numerology that is included in multiple numerologies is sent from the second RAN node to the first RAN node in a setup procedure of an inter-RAN node interface between the first RAN node and the second RAN node, and
the radio resource configuration indicates at least one second numerology different from the reference 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.
