A method and apparatus for interruption handling for V2X communication are provided.
1. A method performed by a first terminal in a wireless communication system, the method comprising:
receiving, from a base station, a control message including a configuration for a configured sidelink grant;
transmitting, to a second terminal, sidelink signal based on the configured sidelink grant for a first sidelink logical channel which is allowed to use the configured sidelink grant;
starting a timer associated with a radio link failure, in case that a consecutive out of synchronization indications for a cell are received from a lower layer;
identifying whether there is a second sidelink logical channel which is not available for the configured sidelink grant;
transmitting, to the second terminal while the timer is running, sidelink signal based on the configured sidelink grant, in case that there is no sidelink logical channel not available for the configured sidelink grant; and
transmitting, to the second terminal while the timer is running, sidelink signal based on a resource from an exceptional transmission pool, in case that there is the second sidelink logical channel not available for the configured sidelink grant.
2. The method of claim 1 , wherein the identifying of whether there is the second sidelink logical channel further comprises identifying whether an indication to use the configured sidelink grant for all of the first sidelink logical channel and the second sidelink logical channel is received from the base station.
3. The method of claim 1 , wherein the identifying of whether there is the second sidelink logical channel further comprises identifying whether an association between the second sidelink logical channel and the configured sidelink grant is received from the base station.
4. The method of claim 1 , wherein the identifying of whether there is the second sidelink logical channel further comprises identifying whether a logical channel priority of the second sidelink logical channel is included in a list of logical channel priorities of the configured sidelink grant.
5. The method of claim 1 , wherein the identifying of whether there is the second sidelink logical channel further comprises identifying whether a logical channel priority of the second sidelink logical channel is equal to or lower than a priority threshold for which the configured sidelink grant cannot be used.
6. A method performed by a second terminal in a wireless communication system, the method comprising:
receiving, from a base station, a control message including a configuration for a configured sidelink grant; and
receiving, from a first terminal, sidelink signal based on the configured sidelink grant for a first sidelink logical channel which is allowed to use the configured sidelink grant,
wherein, while a timer associated with a radio link failure is running, sidelink signal is received from the first terminal based on the configured sidelink grant, in case that there is no sidelink logical channel not available for the configured sidelink grant, and
wherein, while the timer is running, sidelink signal is received from the first terminal based on a resource from an exceptional transmission pool, in case that there is second sidelink logical channel not available for the configured sidelink grant.
7. The method of claim 6 , wherein whether an indication to use the configured sidelink grant for all of the first sidelink logical channel and the second sidelink logical channel is received is identified to determine the second sidelink logical channel.
8. The method of claim 6 , wherein whether an association between the second sidelink logical channel and the configured sidelink grant is received is identified to determine the second sidelink logical channel.
9. The method of claim 6 , wherein whether a logical channel priority of the second sidelink logical channel is included in a list of logical channel priorities of the configured sidelink grant is identified to determine the second sidelink logical channel.
10. The method of claim 6 , wherein whether a logical channel priority of the second sidelink logical channel is equal to or lower than a priority threshold for which the configured sidelink grant cannot be used is identified to determine the second sidelink logical channel.
11. A terminal in a wireless communication system, the terminal comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to:
receive, from a base station, a control message including a configuration for a configured sidelink grant,
transmit, to a second terminal, sidelink signal based on the configured sidelink grant for a first sidelink logical channel which is allowed to use the configured sidelink grant,
start a timer associated with a radio link failure, in case that a consecutive out of synchronization indications for a cell are received from a lower layer,
identify whether there is a second sidelink logical channel which is not available for the configured sidelink grant,
transmit, to the second terminal while the timer is running, sidelink signal based on the configured sidelink grant, in case that there is no sidelink logical channel not available for the configured sidelink grant, and
transmit, to the second terminal while the timer is running, sidelink signal based on a resource from an exceptional transmission pool, in case that there is the second sidelink logical channel not available for the configured sidelink grant.
12. The terminal of claim 11 , wherein the controller is further configured to identify whether an indication to use the configured sidelink grant for all of the first sidelink logical channel and the second sidelink logical channel is received from the base station.
13. The terminal of claim 11 , wherein the controller is further configured to identify whether an association between the second sidelink logical channel and the configured sidelink grant is received from the base station.
14. The terminal of claim 11 , wherein the controller is further configured to identify whether a logical channel priority of the second sidelink logical channel is included in a list of logical channel priorities of the configured sidelink grant.
15. The terminal of claim 11 , wherein the controller is further configured to identify whether a logical channel priority of the second sidelink logical channel is equal to or lower than a priority threshold for which the configured sidelink grant cannot be used.
16. A second terminal in a wireless communication system, the second terminal comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to:
receive, from a base station, a control message including a configuration for a configured sidelink grant, and
