Abstract:
A device to process a channel state information reference signal CSI-RS and further 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 is provided. The subcarriers are grouped into frequency subbands, and at least one subband is scalable with at least one subband parameter for a period of time. A subband parameter is in particular a subcarrier spacing, and in at least one subband at least two different parameters, in particular subcarrier spacings, can be used.
