1. An information transmission method, comprising:
determining, by a access layer of a User Equipment (UE), whether to use duplication transmission according to a Prose Per Packet Reliability (PPPR) of a V2X service and a reliability threshold, wherein the reliability threshold is indicated by RRC signaling, or pre-configured in the UE;
when the UE determine to use the duplication transmission, determining a transmission manner of a Vehicle to everything (V2X) service duplication to be transmitted;
selecting a PC5 air interface carrier for transmitting the V2X service duplication according to a rule corresponding to the transmission manner; and
transmitting the V2X service duplication on the selected PC5 air interface carrier, wherein the V2X service duplication is indicated by a specific logical channel identifier;
wherein the determining a transmission manner of a V2X service duplication to be transmitted comprises:
determining the transmission manner of the V2X service duplication to be transmitted according to a position where a transmitting UE is located;
the position where the transmitting UE is located comprises: the transmitting UE is located in a coverage of the eNB, and the transmitting UE is located out of the coverage of the eNB;
when the transmitting UE is located out of the coverage of the eNB, the transmission manner is a manner in which the UE independently selects a transmission resource; and
when the transmitting UE is located in the coverage of the eNB, a manner in which the eNB schedules or the UE independently selects the transmission resource is determined according to a local policy.
