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 R

Example Embodiment

[0037] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are disclosed.

[0038] It should be noted that in this article, the words "first", "second", "third" and "fourth" are only used to distinguish the same names, rather than implying the relationship between these names or order.

[0039]The embodiment of the present invention proposes a method for realizing simultaneous transmission to multiple destination IDs based on V2X SideLink communication. The present invention modifies the structure of the MAC header in the MAC PDU in the SL-SCH channel, and specifies that the MAC header of one MAC PDU is composed of one or more SL-SCH subheaders and one or more MA...

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...
