Selecting a transmission configuration

A method for wireless communication at a receiving device, comprising:

• selecting, from a group of modulation configurations, a non-coherent modulation configuration based at least in part on a radio frequency spectrum band used by the receiving device to communicate with a transmitting device;
• receiving, from the transmitting device, an indication that a non-coherent single-carrier frequency-domain multiple access (SC-FDMA) mode has been selected for transmitting a set of data;
• receiving, in a symbol period of the radio frequency spectrum band, a time-domain waveform;
• generating a set of frequency-domain symbols from the time-domain waveform using a discrete Fourier transform;
• demapping the set of frequency-domain symbols from a set of subcarriers in the radio frequency spectrum band;
• generating a set of modulated symbols from the demapped set of frequency-domain symbols using an inverse discrete Fourier transform;
• and
• demodulating, based at least in part on the non-coherent modulation configuration, the set of modulated symbols using a differential phase shift keying (DPSK) demodulation to obtain the set of data.

An apparatus for wireless communication at a transmitting device, comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• select, from a group of modulation configurations, a non-coherent modulation configuration based at least in part on a radio frequency spectrum band used by the transmitting device to communicate with a receiving device;
• modulate, based at least in part on the non-coherent modulation configuration, a set of data using a differential phase shift keying (DPSK) modulation to obtain a set of modulated symbols;
• generate a set of frequency-domain symbols from the set of modulated symbols using a discrete Fourier transform;
• transmit, to the receiving device, an indication that a non-coherent single-carrier frequency-domain multiple access (SC-FDMA) mode has been selected for transmitting the set of data;
• and
• transmit, in a symbol period of the radio frequency spectrum band, a time-domain waveform obtained from the set of frequency-domain symbols.
