It is proposed a device to process data to be transmitted via a first radio module of a radio communications network, in which data to be transmitted is mapped on subcarriers and in the radio module subsequently up-converted to a radio frequency higher than the subcarrier frequencies, wherein the subcarriers are grouped into frequency subbands, and wherein at least one subband is scalable with at least one subband parameter, wherein a subband parameter is in particular a subcarrier spacing, and wherein in at least one subband at least two different parameters, in particular subcarrier spacings, can be used.

Device to process data to be transmitted via a first radio module

Embodiments provide apparatuses, methods and computer programs for mobile communication systems comprising base station and mobile transceivers. An apparatus for a base station transceiver (and/or a mobile transceiver) of a mobile communication system, comprises a transceiver module to communicate with the mobile transceiver (and/or base station transceiver) using first and second communication channels, wherein the first channel is more reliable than the second channel. The apparatus further comprises a controller module to control the transceiver module, and to provide a data service to the mobile transceiver (and/or base station transceiver). The data service comprises first and second data packets, wherein the first data packets comprise information related to core data of the data service, and wherein the second data packets comprise information related to optional refinement data for the data service. The first data packets use the first channel, and the second data packets use the second channel.
