Abstract: The disclosure provides message transmission methods and apparatuses, which can be used in various communication systems, for example, a V2X communication system, an LTE-V communication system, a V2V communication system, an IoV communication system, an MTC system, an IoT communication system, an LTE-M communication system, and a M2M communication system. One example method includes that a second terminal device receives a first message, where the first message is a broadcast message from a first terminal device, and the first message includes first data. The second terminal device receives a reception failure message for the first message, where the reception failure message for the first message is a broadcast message from a third terminal device, and the second terminal device broadcasts a second message, where the second message includes the first data.
