Resource sharing among different ofdm numerologies

A transmission method to be performed by a transmission device, comprising the steps of:

• mapping data and/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 the mapped reference signal and/or data, wherein,
• in the step of transmitting the data and/or a reference signal onto the resources, no transmit power is assigned to at least one subcarrier located between a subcarrier of the first numerology and a subcarrier of the second numerology.

A reception method to be performed by a reception device, comprising the steps of:

• receiving data and/or a reference signal in resources of a communication system, and
• de-mapping the data and/or the reference signal from the resources which include subcarriers of a first numerology and subcarriers of 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, wherein,
• in the step of receiving data and/or control information, control information is received to derive to which subcarriers no transmit power is allocated, and no transmit power is allocated to at least one subcarrier located between a subcarrier of the first numerology and a subcarrier of the second numerology.
