Abstract: The present invention relates to a V2V communication method, apparatus, and terminal. The method includes: receiving, by a first terminal, a first scheduling assignment SA message that is sent by a second terminal, where the first SA message includes a first pilot resource and a first diversity multiplexing mode that are used by the second terminal; determining, by the first terminal based on the first pilot resource and the first diversity multiplexing mode, a second pilot resource and a second diversity multiplexing mode that are to be used by the first terminal; and sending, by the first terminal, a data stream to a third terminal based on the second pilot resource and the second diversity multiplexing mode.

Abstract: This application relates to the field of wireless communications, and in particular, to a resource scheduling technology for vehicle to vehicle communication in a wireless communications system. In a resource scheduling method, a first terminal device receives a second-vehicle message sent by at least one second terminal device, where the second-vehicle message carries vehicle status information of the second terminal device. The first terminal device determines a historical resource occupation status of the at least one second terminal device, and selects, based on the vehicle status information indicating a vehicle location and a traveling status of the second terminal device, a first resource used for sending a first-vehicle message.

Abstract: Embodiments of this application disclose a relay transmission method and system, and a related device. The method includes: determining, by a relay terminal, a vehicle existing between a vehicle terminal i and a vehicle terminal j based on vehicle location information in received broadcast messages sent by N vehicle terminals; and when it is obtained through calculation that link quality of a communication link Rij used when the vehicle terminal i and the vehicle terminal j communicate with each other is lower than a preset threshold, forwarding, to the vehicle terminal j, a broadcast message sent by the vehicle terminal i, and forwarding, to the vehicle terminal i, a broadcast message sent by the vehicle terminal j. A relay forwarding function of the relay terminal avoids communication interruption or communication distance limitation caused by blocking due to dynamic and unpredictable factors such as a large vehicle within the Internet of vehicles, thereby improving reliability of message transmission within the Internet of vehicles.
