Abstract: This application provides a sequence-based signal processing method and apparatus. A sequence used for sending a signal on a PUSCH is determined. The sequence is a sequence {x} including N elements, xn is an element in the sequence {xn}, and the determined sequence {xn} is a sequence satisfying a preset condition. Then, a first signal is generated and sent. By using the determined sequence, when a signal is sent on the PUSCH, relatively good sequence frequency domain flatness can be maintained, and a relatively low PAPR. value and a relatively low cross-correlation between sequences can be maintained, thereby satisfying a communications application environment in which a signal is sent on the PUSCH, especially an NR system scenario or an NR similar scenario.
