Abstract

Embodiments relate to a methods and apparatuses for reducing interference between a legacy OFDM signal and a Universal Filtered Multi-Carrier (UFMC) signal. The UFMC signal comprises a first filtered frequency sub-band and at least a second filtered frequency sub-band. The first frequency sub-band comprises a first group of subcarriers, the first frequency sub-band being filtered with a first frequency sub-band specific sideband suppression filter (106-1) for sideband suppression outside of said first frequency sub-band. The second frequency sub-band comprises a second group of subcarriers, the second frequency sub-band being filtered with a second frequency sub-band specific sideband suppression filter (106-2) for sideband suppression outside of said second frequency sub-band. The apparatus (100) comprises a transmitter configured to transmit the OFDM signal and the UFMC signal with a relative delay to each other. The relative delay may be obtained by a delay module (110), for example.
