Abstract

This application discloses a method for mapping a PUSCH signal, a terminal, and a network-side device. The method for mapping a PUSCH signal includes: determining, according to a frequency domain resource allocation type for the terminal and frequency domain resource allocation information for the terminal, a target resource block allocated to a PUSCH, where the target resource block includes a first target VRB or a first target PRB; determining, according to the frequency domain resource allocation type and/or a scheduling mode of the PUSCH, a mapping mode of mapping a PUSCH signal to a second target PRB, where the second target PRB is the first target PRB or a PRB corresponding to the first target VRB; and mapping the PUSCH signal to the second target PRB by using the mapping mode.
