Embodiment 1

[0103] This example is a PC5 single-carrier scenario. PC5 works on F1. The preconfigured parameters are: PSCCH and PSSCH are adjacent, subchannel size is n5, number of subchannels is n10, and subchannel starting resource is 0. The network configuration parameters are: the PSCCH is adjacent to the PSSCH, the size of the sub-channel is n5, the number of sub-channels is n10, and the starting resource of the sub-channel is 3.

[0104] UE1 is an off-network UE, and UE2 is an on-network UE.

[0105] 1: UE1 has V2X data to send, it sends the channel configuration information it uses on the configuration information sending resource, and sends data according to its own configuration information.

[0106] 2: UE2 receives the configuration information sent by UE1 on the configuration information sending resource, obtains the subchannel configuration it uses after parsing, and receives the data of UE1 according to the subchannel configuration of UE1.

[0107] 3: UE2 has V2X data to send...

Abstract

The invention discloses a method and device for transmitting and receiving vehicle-to-everything information through a PC5 interface. The method includes the following steps that: the resource configuration information of a resource pool on the PC5 interface of local user equipment is determined, wherein the resource pool is used for transmitting vehicle-to-everything information; the configuration information is sent to other user equipment which receives the vehicle-to-everything information through the resource pool; the vehicle-to-everything information is sent to the other user equipmentfrom the sub-channels of the resource pool of the PC5 interface according to the configuration information; and configuration information sent by the other user equipment is received, the local user equipment receives vehicle-to-everything information sent by the other user equipment on the corresponding resource pool of the PC5 interface according to the configuration information. With the methodand device of the present invention adopted, consistent configuration can be obtained by both transmitting user equipment and receiving user equipment, and a condition that the transmitting user equipment and the receiving user equipment cannot receive each other' messages due to different configurations can be avoided.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and a device for sending and receiving Internet of Vehicles information through a PC5 interface. Background technique [0002] V2X (Vehicle to Everything) communication is a hot topic in the field of communication at present, and it was officially established in 2015 at the 3GPP RAN#67 meeting. V2X communication mainly includes three aspects: [0003] V2V (Vechile-to-Vechile, vehicle to vehicle): communication between OBU (On Broad Unit, on-board unit) on the vehicle. [0004] V2I (Vechile-to-Infrastructure, lane network): Communication between vehicles and RSU (Road Side Unit, roadside equipment). [0005] V2P (Vechile-to-Pedestrian, vehicle to pedestrian): Communication between vehicles and pedestrians. [0006] Among the above three V2X communication methods, V2V has the highest requirement on delay. The specific delay requirement is that the end-to...
