Abstract

The embodiment of the invention provides an information transmission method, communication equipment and network equipment. The information transmission method comprises the following steps that: first communication equipment sends a request message to network equipment to request the network equipment to schedule resources for transmitting sidewalk information between the first communication equipment and second communication equipment, receives indication information which is sent by the network equipment and is used for indicating the resources, and sends the sidewalk information to the second communication equipment on the resources. According to the embodiment of the invention, the accessibility of the sidewalk information can be ensured.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to an information transmission method, communication equipment and network equipment. Background technique [0002] Vehicle to everything (V2X) communication system can provide including vehicle to vehicle (Vehicle to Vehicle, V2V), vehicle to person (Vehicle to Pedestrian, V2P), vehicle to infrastructure (Vehicle to Infrastructure, V2I) and vehicle to network (Vehicle to Network, V2N) and other intelligent transportation services. Among them, except that the information transmission between V2N uses the uplink and downlink, the other information transmission between V2V, V2I or V2P can communicate on the sidelink if it does not need to be forwarded by network equipment. [0003] Currently, half-duplex mode (half-duplex) is usually used for transmission between communication devices on the sidelink, that is, one communication device cannot transmit and receive a...
