Abstract
A sidelink resource determining method, an apparatus, and a system, to improve reliability of sidelink data transmission when a first terminal does not receive acknowledgment information for a first data packet from a second terminal. According to the method, when the first terminal determines that the first terminal does not receive the acknowledgment information that is for the first data packet and that is fed back by the second terminal, if the first terminal determines that the second terminal fails to decode the first data packet, the first terminal may determine a sidelink resource used to retransmit the first data packet, so that the first data packet can be retransmitted on the re-determined sidelink resource. In this way, reliability of sidelink transmission is improved. The solution may be applied to fields including unmanned driving, automated driving, driver assistance, intelligent driving, connected driving, intelligent network driving, car sharing, and artificial intelligence.
