Abstract: This application provides a resource indication method and a communication apparatus. The method includes: The second node receives first indication information from the first node, where the first indication information includes first resource information, and the first resource information is associated with a first reference signal. The second node determines the first resource information based on the first indication information, where the first resource information is for limiting sending of a to-be-sent signal on a first resource indicated by the first resource information. In this way, the sending of the to-be-sent signal by the second node on the first resource is limited, so that interference of the second node to the third node can be reduced, and network performance and spectrum efficiency can be improved.

Abstract: Embodiments of the present invention disclose a pre-distortion system, including a pre-distortion circuit, a transmission circuit, a power amplifier, a feedback circuit, and a learning circuit. The pre-distortion circuit acquires an in-band intermodulation distortion model coefficient vector, a cross-band modulation distortion model coefficient vector, and an out-of-band intermodulation distortion model coefficient vector that are learned by the learning circuit according to an output signal of the power amplifier, and performs pre-distortion processing on an input digital intermediate frequency signal. Correspondingly, the embodiments of the present invention further disclose a pre-distortion method, which can eliminate impact caused by out-of-band intermodulation distortion on the power amplifier.
