Embodiment Construction

[0047] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0048] It should be noted that the terms "first" and "second" in the description and claims of the present invention and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence.

[0049] In an LTE-based D2D communication system, a system uplink subframe is used as a PSSCH (Physical Sidelink Shared Channel) subframe for transmitting D2D data. The D2D sending end UE indicates the used PSSCH resource in link (ie D2D link) control information SCI (Sidelink Control Information). As a special application of D2D communication mode, V2V system can use D2D communication scheme, that is, use SCI information to indicate the corresponding ...

Abstract

The invention provides a channel transmission method and device for V2X communication. The method comprises the following steps: selecting a channel for transmitting control information and an information format according to the configuration of a channel resource pool of V2X equipment, a transmission mode and a control channel transmission rule; and performing control channel transmission on theV2X equipment based on the selected channel and information format. According to the channel transmission method and device, the channel for transmitting the control information and the information format are selected based on resource pool configuration parameters and a transmission demand, so that the utilization efficiency of system resources is increased and the complexity of blind detection is lowered in the coexistence of same-sub-frame transmission and different-sub-frame transmission for SA (Scheduling Assignment) and related data thereof.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular, to a vehicle-to-vehicle (Vehicle-to-Vehicle, referred to as V2V), a vehicle-to-person V2P (Vehicle to Person), a vehicle-to-infrastructure V2I (Vehicle to Person) in the Internet of Vehicles. toInfrastructure) are collectively referred to as a channel transmission method and device for V2X communication. Background technique [0002] The Internet of Vehicles system refers to the provision of vehicle information through sensors, vehicle terminals, and electronic tags mounted on vehicles, and the use of various communication technologies to realize vehicle-to-vehicle V2V (Vehicle to Vehicle), vehicle-to-person V2P (Vehicle to Person), and vehicle-to-vehicle It is a system that interconnects with the infrastructure V2I (Vehicle to Infrastructure), extracts and shares information on the information network platform, effectively manages and controls vehicles, and provides com...
