Signal phase rotation
This disclosure provides methods, devices, and systems for a wireless communication device to perform signal phase rotation. In some implementations, the wireless communication device may determine a number of phase rotation parameters to be applied to a number of tones of a transmission signal. In some aspects, each of the phase rotation parameters indicates a phase rotation to be applied to each of the tones according to a carrier index range for each of the tones and a bandwidth mode for the transmission signal. In some implementations, the wireless communication device may apply the phase rotation parameters to respective ones of the tones according to the specified phase rotations and the carrier index ranges, and transmit the transmission signal from the wireless communication device according to the applied phase rotation parameters.
