Problems solved by technology

In other words, the sender UE can only transmit related V2X services to one destination ID on one TB block, and cannot simultaneously transmit related V2X services to multiple destination IDs on one TB block
In addition, since the UE selects the available resources in the resource pool, the sub-channel is used as the granularity instead of the RB, so the UE may not be able to find the right resources, and resource waste may lead to a decrease in spectrum utilization.
In addition, MAC SDUs corresponding to multiple destination IDs cannot be multiplexed into one MAC PDU, and need to be transmitted separately, resulting in increased transmission delay and increased control channel overhead

Abstract

The invention discloses a method for transmitting information to multiple destination IDs based on V2X (Vehicle to X) SideLink communication. The method comprises the step that an MAC SDU (Service Data Unit) of each destination ID is multiplexed in an MAC PDU (Protocol Data Unit) when a sender transmits a V2X service to more than two receivers so as to transmit the V2X service to the receivers corresponding to all destination IDs through an SL-SCH (Side Link Synchronization Channel), wherein the MAC PDU structure is applied to a V2X SideLink communication scene on the SL-SCH. The method disclosed by the embodiment of the invention can realize the transmission of the V2X service to multiple destination IDs, and improves the resource utilization rate and the transmission delay.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method for transmitting information to multiple destination IDs (identifications) based on V2X SideLink communication. Background technique [0002] V2X (Vehicle to X), that is, the information exchange between the vehicle and the outside world, is the key technology of the future intelligent transportation system. V2X applications will improve driving safety, reduce congestion and vehicle energy consumption, improve traffic efficiency and in-vehicle entertainment information, etc. It uses vehicle-to-vehicle (V2V, Vehicle-to-Vehicle), vehicle-to-pedestrian (V2P, Vehicle-to-Pedestrian), vehicle-to-roadside infrastructure (V2I, Vehicle-to-Infrastructure) and vehicle-to-application server (V2N) , Vehicle-to-Network) communication as the basis, wireless communication and information exchange and processing between vehicles-X (V2X: vehicles, roads, pedestrians and the Internet, e...
