摘要： A rate matching method including: determining a receiving capability of a receive end, where the receiving capability is used to indicate a maximum data processing volume of the receive end in a first transmission time, and/or the receiving capability is used to indicate a maximum data buffer volume of the receive end in a first transmission time; the first transmission time is used to transmit a first transport block to which a first code block belongs; determining NCB based on the receiving capability, where NCB represents a code block size used for rate matching; performing rate matching on the first code block based on NCB. The receive end can adjust, based on a processing capability and/or a buffer capability that are/is of the receive end in a period of time, the code block size used for rate de-matching, to avoid insufficiency in processing capability and/or buffer overflow at the receive end.
