1. A sidelink data transmission method, wherein the method is performed by a terminal device, and comprises:
calculating a transport block size (TBS) based on a size of an allocated resource and a target resource overhead; wherein the target resource overhead comprises a resource overhead of a physical sidelink feedback channel (PSFCH); and
transmitting sidelink data based on the calculated TBS;
wherein the calculating a TBS based on a size of an allocated resource and a target resource overhead comprises: calculating the TBS based on the size of the allocated resource and a parameter related to the target resource overhead, wherein the parameter is related to the resource overhead of the PSFCH and is obtained in at least one of the following manners:
preconfigured by a network device;
configured by a network device; or,
indicated by using sidelink control information (SCI) or downlink control information (DCI).
