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:
selecting a destination having at least one of a medium access control (MAC) control element (CE) and logical channel with a highest priority among logical channels having a sidelink (SL) data available for transmission and at least one MAC CE for a SL, the logical channel having Bj>0, where the Bj denotes a parameter associated with a logical channel prioritization; and
allocating resources to at least one logical channel selected among logical channels of the selected destination having data available for transmission in a decreasing priority order,
wherein in case that any resources remain, all the logical channels having the SL data available for transmission are served in a strict decreasing priority order until either the SL data for that logical channel or a SL grant is exhausted.
2. The method of claim 1 , wherein the MAC CE is for a sidelink channel state information (SL-CSI) reporting.
3. The method of claim 1 , wherein the MAC CE has higher priority than a logical channel for a SL data transmission.
4. The method of claim 1 , wherein logical channels configured with equal priority is served equally.
5. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
select a destination having at least one of a medium access control (MAC) control element (CE) and logical channel with a highest priority among logical channels having a sidelink (SL) data available for transmission and at least one MAC CE for a SL, the logical channel having Bj>0, where the Bj denotes a parameter associated with a logical channel prioritization, and
allocate resources to at least one logical channel selected among logical channels of the selected destination having data available for transmission in a decreasing priority order,
wherein in case that any resources remain, all the logical channels having the SL data available for transmission are served in a strict decreasing priority order until either the SL data for that logical channel or a SL grant is exhausted.
6. The terminal of claim 5 , wherein the MAC CE is for a sidelink channel state information (SL-CSI) reporting.
7. The terminal of claim 5 , wherein the MAC CE has higher priority than a logical channel for a SL data transmission.
8. The terminal of claim 5 , wherein logical channels configured with equal priority is served equally.
