Abstract: This application provides a method for determining a transport block size and a communication apparatus, which may be used in systems such as vehicle-to-everything, V2X, and V2V. A receive-end terminal device and a transmit-end terminal device may determine a quantity of encoded symbols based on a symbol length used for sidelink communication in a time unit and an scaling factor, and may further determine a transport block size of a data channel based on the quantity of encoded symbols. Therefore, for all slots used for sidelink communication, a same quantity of encoded symbols can be determined, and a same transport block size can be further determined.

Abstract: Embodiments relate to a data transmission method. A relay node receives information that is about an SCMA codebook used by the relay node and that is sent by a destination node. The relay node receives two or more source signals sent by two or more source nodes. The relay node performs network coding on the received two or more source signals. The relay node performs SCMA codebook mapping on a signal obtained after the network coding, so as to obtain at least two modulation symbols. The relay node sends to the destination node, the at least two modulation symbols obtained after the SCMA mapping.
