Abstract
Certain aspects of the present disclosure provide a method of wireless communication at a transmitting device, generally including selecting, based on one or more criteria, a scheme for generating a waveform that accounts for unavailable frequency resources within an allocation of resource elements (REs), obtaining a sequence of frequency domain symbols, generating the waveform by mapping at least some of the sequence of frequency domain symbols to REs within the allocation according to the selected scheme, and outputting the waveform for transmission.

An apparatus for wireless communication, comprising:
- a memory comprising computer-executable instructions;
- and one or more processors configured to execute the computer-executable instructions and cause the apparatus to:
- select, based on one or more criteria, a scheme for generating a waveform that accounts for unavailable frequency resources within an allocation of resource elements (REs);
- obtain a sequence of frequency domain symbols;
- generate the waveform by mapping at least some of the sequence of frequency domain symbols to REs within the allocation according to the selected scheme;
- and
- output the waveform for transmission.
