Abstract:
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with a transmission stream processor used to maintain a lower peak-to-average power ratio (PAPR) for uplink transmissions. In some cases, a UE may map modulated symbols of different signals (or waveforms) to interleaved subsets of frequency resources, and this form of frequency division multiplexing (FDM) may increase the PAPR of an uplink transmission. To reduce the PAPR of uplink transmissions, a transmission stream processor at the UE may support techniques for phase ramping modulated symbols in the time domain prior to mapping the symbols to the frequency resources. These techniques may help to ensure that the signals to be included in an uplink transmission are aligned in such a way that the PAPR of the uplink transmission is reduced.

Claim (Index 1):
A method for wireless communication, comprising:\n applying a phase ramp in the time domain to a first set of symbols to obtain a set of phase-ramped time domain symbols, the first set of symbols being modulated according to a first symbol constellation for a transmission in a symbol period; performing frequency domain spreading on the set of phase-ramped time domain symbols to obtain a first frequency domain signal; mapping the first frequency domain signal to a first subset of a set of subcarriers for the transmission and a second frequency domain signal to a second subset of the set of subcarriers, wherein the second frequency domain signal is based at least in part on a second set of symbols modulated according to a second symbol constellation; generating a time domain waveform for the transmission based at least in part on a frequency to time domain transform of the mapped first and second frequency domain signals to the set of subcarriers; and transmitting the time domain waveform to a receiver.
