Abstract: PAPR suppression includes a first clipping module and a second clipping module. The second clipping module outputs, to the first clipping module, a to-be-clipped signal that satisfies an input condition of the first clipping module, where the input condition includes a peak distribution feature of an input signal. The first clipping module performs first clipping processing on the to-be-clipped signal to obtain a first clipped signal. PAPR suppression is performed based on collaboration between the two clipping modules.

Abstract: Embodiments of this application provide a scheduling method and apparatus, and relate to the communications field. The method includes: Abase station obtains information about predicted interference of N downlink signals of the base station to an uplink signal, where N is an integer greater than 1, and the information about predicted interference is used to indicate predicted interference impact, on the uplink signal, of passive intermodulation signals generated by interaction between the N downlink signals. Then, the base station may perform resource scheduling on the N downlink signals and/or the uplink signal based on the obtained information about predicted interference, where the resource scheduling includes frequency domain resource scheduling and space domain resource scheduling. In this application, the interference impact of the passive intermodulation signals can be effectively reduced, thereby improving system performance and radio resource utilization.
