Patent attributes
The present disclosure relates to the field of communications and provides a data transmission method for sidelink communication and a device. The method can include a first Internet-of-vehicle device that determines a destination reception geographical location of a user data packet and generates a MAC PDU corresponding to the user data packet. The MAC PDU can carry the destination reception geographical location. The first Internet-of-vehicle device encodes and modulates the MAC PDU to obtain physical layer data, and sends the physical layer data on a target time-frequency resource. A second Internet-of-vehicle device compares the destination reception geographical location carried by the MAC PDU to determine whether to receive the user data packet.
