Abstract
A transmitting apparatus for a wireless communication system, where the wireless communication system includes an OFDM based waveform corresponding to a plurality of pre-defined subcarrier spacing values including at least a first subcarrier spacing value Δf1 and at least a second subcarrier spacing value Δf2. The transmitting apparatus includes a processor and a transmitter where the processor is configured to generate a signal S1 that is a NSF time repetition of an another signal S2. A duration of the another signal S2 is 1/Δf2, NSF=Δf2/Δf1 is an integer greater than 1, and the transmitter is configured to transmit a symbol comprising S1.
