1. A method for determining transport block size for sidelink transmission, comprising:
determining, by a terminal device, number of resource elements (REs) for a physical sidelink shared channel (PSSCH) in a second resource according to a first resource used for transmitting a physical sidelink control channel (PSCCH) and the second resource indicated by the PSCCH and used for transmitting the PSSCH, the first resource at least partially overlapping with the second resource; and
determining, by the terminal device, a transport block size (TBS) for the PSSCH according to the number of the REs for the PSSCH;
wherein determining, by the terminal device, the TBS for the PSSCH according to the number of the REs for the PSSCH comprises:
determining, by the terminal device, number of information bits according to the number of the REs for the PSSCH; and
determining, by the terminal device, the TBS according to the number of the information bits, wherein the number of the information bits satisfies Ninfo=NRE×R×Qm×v, NRE represents the number of the REs for the PSSCH, R represents a transmission bit rate, Qm represents a modulation order, and v represents number of transmission layers;
wherein determining, by the terminal device, the TBS according to the number of the information bits comprises:
obtaining, by the terminal device, quantified number of information bits by quantifying the number of the information bits; and
determining, by the terminal device, the TBS according to the quantified number of the information bits.
