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.

Abstract: This disclosure provides a carrier signal processing method and apparatus. In the method, clipping factors are determined based on scheduling information corresponding to at least two respective carrier signals in a first time unit, the clipping factors correspond to the at least two respective carrier signals in the first time unit and are used for clipping processing a combination signal of the at least two carrier signals in the first time unit. The at least two carrier signals and the clipping factors are sent to a radio unit for processing. In this solution, clipping factors are matched in real time with scheduling information respectively corresponding to a plurality of carrier signals in the first time unit, to improve clipping performance.
