Embodiments of this disclosure provide a method and a terminal for allocating PDSCH time domain resources, and a computer-readable storage medium, where the method is applied to a terminal and includes: starting buffering or receiving, by the terminal, a PDSCH no earlier than a time domain limiting location of the PDSCH, where when SCS of a PDCCH is smaller than SCS of the PDSCH, a time domain location of the PDSCH is not earlier than the time domain limiting location of the PDSCH.
