Abstract: An adaptive modulation and coding method includes: receiving, by a base station, a channel quality indicator CQI sent by a first terminal; determining, by the base station, a subframe for scheduling the first terminal; determining, by the base station, a subframe set to which the subframe belongs, where the subframe set is a first subframe set or a second subframe set, and the first subframe set and the second subframe set correspond to different CQI adjustment amounts; adjusting, by the base station, the CQI based on a CQI adjustment amount corresponding to the subframe set to which the subframe belongs; and determining, by the base station based on an adjusted CQI, a modulation and coding scheme MCS for scheduling the first terminal.

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.
