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 30):
An apparatus for wireless communication, in a system comprising:\n a processor; memory in electronic communication with the processor; and instructions stored in the memory and executable by the processor to cause the apparatus to:\n receive a time domain waveform from a transmitter; \n generate a frequency domain waveform based at least in part on a time to frequency domain transform of the received time domain waveform to obtain a first frequency domain signal mapped to a first subset of a set of subcarriers and a second frequency domain signal mapped to a second subset of the set of subcarriers; \n perform a frequency to time domain transform on the first frequency domain signal to obtain a first set of phase-ramped time domain symbols; \n apply an inverse phase ramp in the time domain to the first set of phase-ramped time domain symbols to obtain a first set of time domain symbols; and \n identify, based at least in part on the first set of time domain symbols, a first set of symbols modulated according to a first symbol constellation.
