Abstract: The present invention provides an apparatus for constructing a pre-DFT sample sequence for an OFDM-signal, comprising: a processor configured to construct a pre-DFT sample sequence with a pre-defined length such that it comprises data; and a PTRS-group, wherein the last sample of the PTRS-group is placed within the pre-DFT sample sequence at a pre-defined position located B samples before the end of the pre-DFT sample sequence.
