Abstract
In some implementations, a transmitter may transmit an indication of a frequency interleaver, from a set of frequency interleavers, that provides an interleaved sequence for a communication, the frequency interleaver being selected based on a peak-to-average power ratio (PAPR) of the interleaved sequence. The transmitter may transmit the communication including the interleaved sequence, and an index of the interleaved sequence being associated with an input signal that is interleaved via the frequency interleaver when the input signal is in a frequency domain.

A transmitter for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to cause the transmitter to:
- transmit an indication of a frequency interleaver, from a set of frequency interleavers, that provides an interleaved sequence for a communication, the frequency interleaver being selected based on a peak-to-average power ratio (PAPR) of the interleaved sequence;
- and
- transmit the communication, including the interleaved sequence, and an index of the interleaved sequence being associated with an input signal that is interleaved via the frequency interleaver when the input signal is in a frequency domain.
A receiver for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to cause the receiver to:
- receive an indication of a frequency interleaver, from a set of frequency interleavers, that provides an interleaved sequence for a communication, the frequency interleaver being selected based on a peak-to-average power ratio (PAPR) of the interleaved sequence;
- and
- receive the communication including the interleaved sequence, an index of the interleaved sequence being associated with an input signal that is interleaved via the frequency interleaver when the input signal is in a frequency domain.
A method of wireless communication performed by a transmitter, comprising:
- transmitting an indication of a frequency interleaver, from a set of frequency interleavers, that provides an interleaved sequence for a communication, the frequency interleaver being selected based on a peak-to-average power ratio (PAPR) of the interleaved sequence;
- and
- transmitting the communication including the interleaved sequence, and an index of the interleaved sequence being associated with an input signal that is interleaved via the frequency interleaver when the input signal is in a frequency domain.
A method of wireless communication performed by a receiver, comprising:
- receiving an indication of a frequency interleaver, from a set of frequency interleavers, that provides an interleaved sequence for a communication, the frequency interleaver being selected based on a peak-to-average power ratio (PAPR) of the interleaved sequence;
- and
- receiving the communication including the interleaved sequence, and an index of the interleaved sequence being associated with an input signal that is interleaved via the frequency interleaver when the input signal is in a frequency domain.
