FIELD: information technology.SUBSTANCE: apparatus is configured to receive a first signal comprising at least one frequency domain value; map the first signal to a second signal comprising at least two clusters, each cluster comprising a whole number multiple of a first number of subcarrier values, wherein each first signal value is mapped to one of the at least two clusters and each of the at least one first signal values in the frequency domain is mapped to a subcarrier value of one of the at least two clusters depending on the cluster selection.EFFECT: flexibility when organising and scheduling carriers.24 cl, 11 dwg |
