Abstract: Embodiments of this application disclose a method for reducing a peak-to-average power ratio PAPR, and a communication apparatus, and are applied to a transmitting system including a power amplifier. In the method, a reserved resource may be determined based on a first unscheduled resource in transmission bandwidth and/or a second unscheduled resource in guard bandwidth, and a fixed reserved resource in a conventional technology does not need to be used. Therefore, flexibility of determining the reserved resource can be improved, and flexibility of reducing a peak-to-average power ratio PAPR in a frequency domain resource reservation TR manner can further be improved.
