Method and terminal for communicating with other terminal in wireless communication system
Presented in one embodiment of the present invention is a method by which a first terminal communicates with a second terminal in a wireless communication system, comprising the steps of: allowing the first terminal to receive control information from a base station; allowing the first terminal to select a transmission resource on the basis of the control information; and allowing the first terminal to communicate with a second terminal on the basis of the transmission resource, wherein the control information is transmitted to the first terminal and the second terminal by the base station, and the control information includes information for preventing a transmission resource selection collision between the first terminal and the second terminal. The first terminal is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.
1. A method of communicating with a second user equipment by a first user equipment in a wireless communication system, the method comprising:
receiving by the first user equipment control information from a base station;
selecting by the first user equipment a transmission resource based on the control information; and
communicating by the first user equipment with the second user equipment based on the transmission resource,
wherein the control information is transmitted to the first user equipment and the second user equipment by the base station and
wherein the control information includes a first backoff value for the first user equipment and a second back off value for the second user equipment, and
wherein the first backoff value and the second backoff value are spaced apart from each other by a prescribed time interval for preventing collision of transmission resource selection between the first user equipment and the second user equipment.
2. The method of claim 1 , wherein the first user equipment and the second user equipment supports different sidelink transmission modes.
3. The method of claim 2 , wherein the first user equipment is a user equipment supporting a transmission mode 3 and wherein the second user equipment is a user equipment supporting a transmission mode 4.
4. The method of claim 1 , further comprising selecting by the first user equipment a transmission resource based on a sensing result and the first backoff value.
5. The method of claim 1 , wherein the control information includes information indicating a candidate resource set including a plurality of transmission resources and wherein the method further comprises selecting by the first user equipment at least one of a plurality of the transmission resources in the candidate resource set.
6. The method of claim 5 , wherein the information indicating the candidate resource set is further transmitted to the second user equipment by the base station.
7. The method of claim 1 , further comprising transmitting by the first user equipment information indicating a request for preemption of the transmission resource to the base station,
wherein a response to the request for the preemption is transmitted to the second user equipment by the base station.
8. The method of claim 7 , wherein the information indicating the request for preemption includes information indicating at least one of priority, reliability, or latency budget.
9. A first user equipment communicating with a second user equipment in a wireless communication system, the first user equipment comprising:
a transceiver; and
a processor configured to receive control information from a base station, select a transmission resource based on the control information, and communicate with the second user equipment based on the transmission resource,
wherein the control information is transmitted to the first user equipment and the second user equipment by the base station and
wherein the control information includes a first backoff value for the first user equipment and a second back off value for the second user equipment, and
wherein the first backoff value and the second backoff value are spaced apart from each other by a prescribed time interval for preventing collision of transmission resource selection between the first user equipment and the second user equipment.
10. The first user equipment of claim 9 , wherein the first user equipment communicates with at least one of a mobile terminal, a network, or an autonomous vehicle other than the devices.
11. The first user equipment of claim 9 , wherein first user equipment implements at least one Advanced Driver Assistance System (ADAS) function based on a signal for controlling a motion of the first user equipment.
12. The first user equipment of claim 9 , wherein the first user equipment switches a driving mode of a device from an autonomous driving mode to a manual driving mode by receiving a user's input, and vice versa.
13. The first user equipment of claim 9 , wherein the first user equipment performs an autonomous driving based on external object information and wherein the external object information comprises at least one of information on a presence or non-presence of an object, location information of the object, distance information between the first user equipment and the object, or relative speed information between the first user equipment and the object.
14. The first user equipment of claim 9 , wherein the first user equipment is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.
