Taking downlink shared channel as an example, before channel coding and decoding data in the 5 th generation mobile communication technology (also referred to as 5G), a base station and a terminal need to independently determine a Transport Block Size (TBS) and a coding length. The determination of the coding length can be calculated according to the available time-frequency resources and the modulation format of the scheduling; the TBS requires a set of calculation procedures to ensure that the base station and the terminal obtain the same value according to the same scheduling parameter calculation. After the base station or the terminal calculates the TBS, the base station or the terminal calculates an effective code rate of the data to be transmitted according to the TBS, a Cyclic Redundancy Code (CRC) length, and a coding length.
