1. An apparatus for serving a plurality of user equipments in a wireless communication system,
wherein, for transmitting data of a plurality of user equipments, which comprise at least a first user equipment and a second user equipment, on resources shared by the plurality of user equipments, the apparatus is configured to:
modulate the first data signal and the second data signal using different waveforms prior to superimposing the first and second data signals, the first data signal of the first user equipment being modulated using a first waveform, and the second data signal of the second user equipment being modulated a second waveform, the first waveform being different from the second waveform;
process the first data signal and the second data signal according to
a pathloss or signal attenuation on first and second channels between the first and second user equipments and the apparatus, or a geographical location of the first user equipment relative to the apparatus and the geographical location of the second user equipment relative to the apparatus;
superimpose the first data signal and the second data signal;
select the first and second waveforms for modulating the first data signal and the second data signal dependent on channel properties of the first and second channels between the first and second user equipments and the apparatus; and
signal to the first user equipment the first waveform used for the modulation of the first data signal and the second waveform used for the modulation of the second data signal, and signal to the second user equipment only the second waveform used for the modulation of the second data signal, and
wherein the first user equipment is closer to the apparatus than the second user equipment or has a pathloss or signal attenuation on the first channel between the first user equipment and the apparatus less than a pathloss or signal attenuation on the second channel between the second user equipment and the apparatus.
