US 12,712,775 B2 · Carrier signal processing method, communication apparatus, and communication system

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.
