Information transmission and reception method and apparatus

An information reception method, comprising:

• monitoring one or more PC5 air interface carriers according to indication information from a transmitting User Equipment (UE) and/or pre-configuration information;
• and
• receiving a Vehicle to everything (V2X) service duplication transmitted by the transmitting UE on the PC5 interface carrier according to a corresponding identifier of the V2X service duplication, wherein the V2X service duplication is indicated by a specific logical channel identifier,
• wherein the V2X service duplication is a V2X service duplication determined by the transmitting UE by determining a transmission manner of a V2X service duplication to be transmitted, selecting, according to a rule corresponding to the transmission manner, the PC5 air interface carrier for transmitting the V2X service duplication and transmitting on the selected PC5 air interface carrier;
• wherein before the V2X service duplication is transmitted by the transmitting UE, determining, by a access layer of the transmitting 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 transmitting UE;
• wherein 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.

An information transmission apparatus, applied to a transmitting User Equipment (UE) and comprising:

• a access layer of the transmitting UE, configured to determine 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 transmitting UE;
• a determination module, configured to, when the UE determine to use the duplication transmission, determine a transmission manner of a Vehicle to everything (V2X) service duplication to be transmitted;
• a selection module, configured to select, according to a rule corresponding to the transmission manner, a PC5 air interface carrier for transmitting the V2X service duplication;
• and
• a first transmission module, configured to transmit 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 determination module is further configured to determine, according to a position where a transmitting UE is located, the transmission manner of the V2X service duplication to be transmitted;
• 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.
