Abstract: Provided a CPG scheduling method and system. The method includes that: peak cancellation components generate and send a CPG calling request to a CPG scheduling component; the CPG scheduling component configures at least one CPG to the peak cancellation component corresponding to the CPG calling request from a CPG sharing resource pool to generate at least one cancellation pulse according to a scheduling strategy and the CPG calling request; and the CPG scheduling component receives the at least one cancellation pulse generated by the at least one configured CPG according to the CPG calling request, and transmits the at least one cancellation pulse to the peak cancellation components corresponding to the CPG calling request to implement peak cancellation processing. By implementing the present disclosure, the problem of incapability in accomplishing all peak cancellation tasks of a peak cancellation component of a certain stage in the related art is solved.
