Method and device for transmitting vehicle-to-vehicle communication message in wireless communication system
The purpose of the present disclosure is to deliver a vehicle-to-vehicle (V2V) message in a wireless communication system. An operation method of an integrated access and backhaul (LAB) node may comprise the steps of: establishing a directlink connection with a terminal; receiving data including an event message from the terminal through the directlink connection; and transmitting system information including the event message to at least one terminal.
1 . A method for operating an integrated access and backhaul (IAB) node in a wireless communication system, the method comprising:
establishing a directlink connection with a terminal;
receiving data including an event message from the terminal through the directlink connection;
generating control information indicating whether to deliver the event message to a parent node; and
transmitting system information to at least one terminal,
wherein the IAB node includes an IAB-mobile terminal (MT) and an IAB-distributed unit (DU),
wherein the IAB-MT is a component for connecting with the parent node,
wherein the IAB-DU is a component for connecting with at least one child node, including the terminal,
wherein the data includes the event message that is transmitted to the at least one terminal through the system information, and
wherein the control information includes a number of hops to which the event message is delivered.
2 . The method of claim 1 , further comprising:
transmitting the event message to a parent IAB node through a wireless backhaul link.
3 . The method of claim 1 , further comprising:
determining, based on the control information, whether or not to deliver the event message to a parent IAB node.
4 . The method of claim 3 , wherein an initial value of the control information is provided by an IAB donor during an initial connection with the IAB donor.
5 . The method of claim 3 , wherein the initial value of the control information is determined based on the event message.
6 . The method of claim 1 , wherein the directlink connection is established by signaling that uses a reserved resource for the directlink.
7 . An integrated access and backhaul (IAB) node in a wireless communication system, the IAB node comprising:
a transceiver; and
a processor coupled with the transceiver, and configured to:
establish a directlink connection with a terminal,
receive data including an event message from the terminal through the directlink connection,
generate control information indicating whether to deliver the event message to a parent node, and
transmit system information to at least one terminal,
wherein the IAB node includes an IAB-mobile terminal (MT) and an IAB-distributed unit (DU),
wherein the IAB-MT is a component for connecting with the parent node,
wherein the IAB-DU is a component for connecting with at least one child node, including the terminal,
wherein the data includes the event message that is transmitted to the at least one terminal through the system information, and
wherein the control information includes a number of hops to which the event message is delivered.
8 . The IAB node of claim 7 , wherein the processor is further configured to:
transmit the event message to a parent IAB node through a wireless backhaul link.
9 . The IAB node of claim 7 , wherein the processor is further configured to:
determine, based on the control information, whether or not to deliver the event message to a parent IAB node.
10 . The IAB node of claim 9 , wherein an initial value of the control information is provided by an IAB donor during an initial connection with the IAB donor.
11 . The IAB node of claim 9 , wherein the initial value of the control information is determined based on the event message.
12 . The IAB node of claim 7 , wherein the directlink connection is established by signaling that uses a reserved resource for the directlink.
13 . A device comprising at least one memory and at least one processor functionally connected to the at least one memory, wherein the at least one processor controls the device to:
establish a directlink connection with a terminal,
receive data including an event message from the terminal through the directlink connection,
generating control information indicating whether to deliver the event message to a parent node; and
transmit system information to at least one terminal,
wherein the IAB node includes an IAB-mobile terminal (MT) and an IAB-distributed unit (DU),
wherein the LAB-MT is a component for connecting with the parent node,
wherein the IAB-DU is a component for connecting with at least one child node, including the terminal,
wherein the data includes the event message that is transmitted to the at least one terminal through the system information, and
wherein the IAB node selectively performs delivery of the event message to the parent node based on control information.
