1. A method of wireless communication, comprising:
receiving, by a user equipment (UE), resource allocation indicating data tones and peak reduction tones (PRTs) with respect to each component carrier (CC) of a plurality of CCs, wherein the resource allocation indicates data tone locations within a first bandwidth of a first CC of the plurality of CCs and within a second bandwidth of a second CC of the plurality of CCs, and wherein the resource allocation indicates PRT locations within at least one of the first bandwidth or the second bandwidth according to one or more PRT location sequences; and
transmitting, by the UE, a data transmission comprising one or more waveforms configured according to the resource allocation.
