Abstract
Aspects described herein relate to determining multiple waveforms for transmitting wireless communications. A control waveform can be determined for transmitting a control information transmission related to a data transmission as one of multiple waveforms. A data waveform can be determined for transmitting the data transmission as one of the multiple waveforms. The control information transmission can be transmitted based on the control waveform, and the data transmission can be transmitted based on the data waveform.
