Method for reporting feedback information for V2X communication and apparatus therefor
A method for processing signals by a user equipment in a V2X (Vehicle-to-Everything) communication system is disclosed. The method includes steps of receiving, from a network, a counting request message including information about at least one V2X service type and at least one V2X UE type; and transmitting a counting response message to the network, when a V2X UE type of the UE is included in the at least one V2X UE type, wherein the counting response message includes information about at least one of a location of the UE, a direction of the UE or a velocity of the UE.
1. A method for processing signals by a user equipment (UE) in a V2X (Vehicle-to-Everything) communication system, the method comprising:
receiving, from a network, a first message including information about at least one V2X UE type and a time interval represented by a start time and a stop time;
when a current time is within the start time and the stop time, scaling down a reporting period for reporting a second message as a response of the first message; and
transmitting the second message to the network periodically according to the scaled down reporting period,
wherein, when the current time is not within the start time and the stop time, the second message is transmitted periodically according to an initially configured reporting period.
2. The method of claim 1 , wherein the at least one V2X UE type comprising at least one of a Pedestrian UE (P-UE), a Vehicle UE (V-UE), or a UE-type road side unit (RSU).
3. The method of claim 1 , wherein the first message includes information about at least one V2X service type,
wherein transmitting the second message comprises transmitting the second message when the UE is interested in the at least one V2X service type or when the UE is currently receiving the at least one V2X service type.
4. The method of claim 3 , wherein the at least one V2X service type comprises at least one of a Vehicle-to-Pedestrian (V2P) service, a Vehicle-to-Infrastructure (V2I) service, or a Vehicle-to-Vehicle (V2V) service.
5. The method of claim 1 , wherein the first message includes information about an area in which the at least one V2X service type is provided,
wherein transmitting the second message comprises transmitting the second message when the UE is in the area in which the at least one V2X service type is provided.
6. A user equipment (UE) in a V2X (Vehicle-to-Everything) communication system, the UE comprising:
a radio frequency (RF) unit; and
a processor connected with the RF unit and configured to receive, from a network, a first message including information about at least one V2X UE type and a time interval represented by a start time and a stop time, to scale down a reporting period for reporting a second message as a response of the first message when a current time is within the start time and the stop time, and to transmit the second message to the network periodically according to the scaled down reporting period,
wherein, when the current time is not within the start time and the stop time, the second message is transmitted periodically according to an initially configured reporting period.
7. The UE of claim 6 , wherein the at least one V2X UE type comprising at least one of a Pedestrian UE (P-UE), a Vehicle UE (V-UE), or a UE-type road side unit (RSU).
8. The UE of claim 6 , wherein the first message includes information about at least one V2X service type,
wherein the processor is further configured to transmit the second message when the UE is interested in the at least one V2X service type or when the UE is currently receiving the at least one V2X service type.
9. The UE of claim 8 , wherein the at least one V2X service type comprises at least one of a Vehicle-to-Pedestrian (V2P) service, a Vehicle-to-Infrastructure (V2I) service, or a Vehicle-to-Vehicle (V2V) service.
10. The UE of claim 6 , wherein the first message includes information about an area in which the at least one V2X service type is provided,
wherein the processor is further configured to transmit the second message when the UE is in the area in which the at least one V2X service type is provided.
