1. An integrated circuit configured to operate a transmission device, the integrated circuit comprising:
control circuitry which, in operation, maps data or a reference signal onto resources of a communication system, the resources including subcarriers of a first numerology and a second numerology, wherein the first numerology and the second numerology differ at least by subcarrier spacing and the subcarriers of the first and the second numerologies are frequency-multiplexed on a subcarrier basis; and
transmitting circuitry which, in operation, transmits the mapped data or reference signal,
wherein:
the control circuitry, in operation, assigns no transmit power to at least one subcarrier located between a subcarrier of the first numerology and a subcarrier of the second numerology,
the subcarriers of the first numerology are orthogonal to each other;
the subcarriers of the second numerology include:
inter-numerology-orthogonal subcarriers, each of which is centrally aligned with a subcarrier of the first numerology, and
non-inter-numerology-orthogonal subcarriers not centrally aligned with any subcarrier of the first numerology and located between two adjacent subcarriers of the first numerology; and
the control circuitry, in operation, assigns no transmit power to at least one of the non-inter-numerology-orthogonal subcarriers.
