<p>A method and device for data broadcast control and data broadcast in a vehicle network, relating to wireless communication field, is used to resolve the problem how to jointly transmitting data packets by multiple Road Side Units (RSU) in the vehicle network. In the present invention, after a control device divides the data to be sent into multiple data blocks, the control device sends the divided multiple data blocks to each RSU which covers the current lane. The control device generates a RSU allocation scheme of multiple data blocks according to the number of the data blocks that each RSU can broadcast. The control device sends a control command to the RSU to which the data blocks are allocated according to the RSU allocation scheme, so as to indicate the data blocks which are needed to be broadcast by the RSU. The RSU broadcasts the data blocks indicated by the control command to an On-Board Unit (OBU). The present invention solves the problem that how to jointly transmitting data packets by multiple RSUs in the vehicle network.</p> |
