Abstract

Embodiments of the present disclosure relate to relate to an access node, user equipment, apparatuses, methods, and computer programs for a communication system. An apparatus (10) for a wireless transmitter device (100) comprises a transmitter module (12) for transmitting wireless transmissions and a processing module (14), which is configured to control the transmitter module (12). The processing module (14) is further configured to generate one or more transmit symbols in a Delay-Doppler domain to obtain a Delay-Doppler representation; transform the Delay-Doppler representation into a Time-Frequency domain to obtain a Time-Frequency representation, the Time-Frequency representation having a first bandwidth and a first duration; add pilot symbols to the Time-Frequency representation to obtain a Time-Frequency representation with an extended second bandwidth or an extended second duration; transform the Time-Frequency representation with the extended second bandwidth or the extended second duration to the time domain to obtain a time domain representation; and transmit the time domain representation to a wireless receiver device (200).
