Method and apparatus for handling configured grant type 1 for vehicle-to-everything (V2X) communication
A communication method and system for converging a 5 th generation (5G) communication system for supporting higher data rates beyond a 4 th generation (4G) system with a technology for Internet of things (IoT) are provided. The communication method and system may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method performed by a terminal in a wireless communication system is provided. The method includes identifying that sidelink channel state information (SL-CSI) reporting is triggered; identifying whether SL resources are allocated for new transmission; performing a logical channel prioritization for the SL resources; and determining whether to trigger a scheduling request for the SL-CSI reporting based on a result of the logical channel prioritization.
1. A method performed by a terminal in a wireless communication system, the method comprising:
identifying whether sidelink (SL) resources are allocated for new transmission, in case that sidelink channel state information (SL-CSI) reporting is triggered;
in case that the SL resources are allocated for the new transmission, identifying whether the SL resources can accommodate a media access control (MAC) control element (CE) and a subheader for the SL-CSI reporting based on a result of a logical channel prioritization; and
triggering a scheduling request for the SL-CSI reporting in case that the SL resources cannot accommodate the MAC CE and the subheader for the SL-CSI reporting.
2. The method of claim 1 , further comprising:
in case that the SL resources are not allocated for the new transmission, triggering the scheduling request.
3. The method of claim 1 , further comprising:
in case that the SL resources can accommodate the MAC CE and the subheader for the SL-CSI reporting, determining to not trigger the scheduling request for the SL-CSI reporting.
4. The method of claim 1 , further comprising:
starting a timer based on triggering the SL-CSI reporting.
5. The method of claim 4 , further comprising:
receiving, from a base station, configuration information on a value of the timer.
6. The method of claim 4 , further comprising:
stopping the timer for the triggered SL-CSI reporting based on transmitting a MAC CE for the SL-CSI reporting.
7. The method of claim 4 , further comprising:
upon expiry of the timer for the triggered SL-CSI reporting, cancelling the triggered SL-CSI reporting.
8. The method of claim 4 , wherein the timer is maintained for each pair of a source layer-2 identifier and a destination layer-2 identifier corresponding to PC5-radio resource control (RRC) connection.
9. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
identify whether sidelink (SL) resources are allocated for new transmission in case that sidelink channel state information (SL-CSI) reporting is triggered,
in case that the SL resources are allocated for the new transmission, identifying whether the SL resources can accommodate a media access control (MAC) control element (CE) and a subheader for the SL-CSI reporting based on a result of a logical channel prioritization, and
trigger a scheduling request for the SL-CSI reporting on a result of the logical channel prioritization in case that the SL resources cannot accommodate the MAC CE and the subheader for the SL-CSI reporting.
10. The terminal of claim 9 , wherein the controller is further configured trigger the scheduling request in case that the SL resources are not allocated for the new transmission.
11. The terminal of claim 9 , wherein the controller is further configured to determine to not trigger the scheduling request for the SL-CSI reporting in case that the SL resources can accommodate the MAC CE and the subheader for the SL-CSI reporting.
12. The terminal of claim 9 , wherein the controller is further configured to start a timer based on triggering the SL-CSI reporting.
13. The terminal of claim 12 , wherein the controller is further configured to receive, from a base station via the transceiver, configuration information on a value of the timer.
14. The terminal of claim 12 , wherein the controller is further configured to stop the timer for the triggered SL-CSI reporting based on transmitting a MAC CE for the SL-CSI reporting.
15. The terminal of claim 12 , wherein the controller is further configured to cancel the triggered SL-CSI reporting upon expiry of the timer for the triggered SL-CSI reporting.
16. The terminal of claim 12 , wherein the timer is maintained for each pair of a source layer-2 identifier and a destination layer-2 identifier corresponding to PC5-radio resource control (RRC) connection.
