1. A wireless device configured for waveform selection, the wireless device comprising:
a receiver configured to receive a first indication of a first selected waveform from a network node, the first indication of the first selected waveform indicating a modulation and coding scheme, MCS, for the first selected waveform, at least the first selected waveform being selected together with a transport block size, TBS:
if the TBS is less than a predetermined threshold and for the indicated MCS, the first selected waveform is to be used by the wireless device for transmission;
if the TBS is greater or equal to the predetermined threshold, a second selected waveform is to be used by the wireless device;
one or both of the first selected waveform and the second selected waveform being selected from an MCS table, the MCS table including a plurality of modulation order values and a plurality of code rate values, each modulation order value that is unique corresponding to one of a first code rate value and a second code rate value of the plurality of code rate values, the first code rate value and the second code rate value being different, the first code rate value corresponding to the first selected waveform, the second code rate value corresponding to the second selected waveform; and
a transmitter configured to transmit using one of the first selected waveform and the second selected waveform based at least on the first indication.
