Abstract: A data transmission method and apparatus are applicable to fields such as V2X, intelligent driving, and connected vehicles. A probability of a collision between a high-priority PSSCH and a low-priority PSSCH is reduced, thereby improving QoS of the high-priority PSSCH. The method includes: obtaining resource pool configuration information including first resource pool information and second resource pool information, where the first resource pool information indicates a first resource pool, and the second resource pool information indicates a second resource pool; obtaining a first priority value corresponding to a physical sidelink shared channel PSSCH; when the first priority value is less than a first priority threshold, determining, in a partial-sensing-selection-based resource determination mechanism and/or a random-selection-based resource determination mechanism in the first resource pool, a resource for sending the PSSCH.
