1. A PUSCH transmission method, comprising:

  • sending downlink control signaling in a first subframe by a base station, wherein the downlink control signaling instructs user equipment (UE) to transmit a physical uplink shared channel (PUSCH), wherein the downlink control signaling carries downlink control information, and the downlink control information is used to indicate a subframe for transmitting the PUSCH and a scaled-up physical resource block (PRB) quantity, wherein the subframe for transmitting the PUSCH is a special subframe;

    scaling down, by the base station, the scaled-up PRB quantity; and

    receiving according to the scaled down PRB quantity, by the base station, the PUSCH in the subframe indicated by the downlink control information,wherein the scaling down, by the base station, of the scaled-up PRB quantity comprises;

    scaling down the scaled-up PRB quantity PRB_2 to obtain the scaled down PRB quantity PRB_1 by using a scale factor Sf, wherein the PRB_1 satisfies;


    PRB_1=└

    PRB_2×

    Sf

    or PRB_1=max{└

    PRB_2×

    Sf

    , 1},wherein └

    *┘

    indicates rounding down.
