Abstract: A transmitting device communicates with a receiving device an indication to apply PAPR reduction for a data transmission. The transmitting device applies a first PAPR reduction signal and a second PAPR reduction signal to the data transmission to reduce at least one signal peak of the data transmission to yield a transmission signal, where the first PAPR reduction signal includes a first set of PRTs that does not overlap with data tones and the second PAPR reduction includes a second set of PRTs that overlaps with the data tones and does not overlap with reserved tones. The transmitting device transmits the transmission signal to the receiving device.

Abstract: Wireless communications systems and methods related to bandwidth-efficient utilization of peak reduction tone resource are provided. An example method of wireless communications performed by a user equipment (UE) includes receiving, from a base station in a first subband, a resource allocation indicating a set of transmission tones comprising a set of first data tones, a set of second data tones and a set of peak reduction tones (PRTs). The resource allocation can indicate the set of first data tones overlaps at least a portion of the set of PRTs at respective locations of a set of PRT locations and the set of second data tones is arranged at a set of data tone locations within a particular bandwidth. The UE can communicate, with the base station in a second subband, a data transmission using an outgoing waveform based at least in part on the resource allocation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may interleave a signal, that is to be transmitted using discrete Fourier transform (DFT) spread orthogonal frequency-division multiplexing (DFT-s-OFDM), and a negative of the signal to obtain an interleaved signal prior to performing a DFT on the interleaved signal. The UE may transmit a DFT-s-OFDM signal that is based at least in part on the interleaved signal. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a resource allocation indicating a plurality of transmission tones comprising a subset of data tones of a plurality of data tones and a subset of peak reduction tones (PRTs) of a plurality of PRTs, wherein the resource allocation indicates a plurality of data tone locations and a plurality of PRT locations within a particular bandwidth, wherein a subset of PRT locations of the plurality of PRT locations are arranged relative to a subset of data tone locations of the plurality of data tone locations according to a PRT sequence corresponding to a set of allocated frequency resources; and transmit a data transmission using a waveform based at least in part on the resource allocation. Numerous other aspects are provided.
