Question: For a UE (User Equipment) supporting Rel-15 V2X sidelink communication, what is the mandatory minimum value of T2 for resource selection in V2X sidelink communication?
Option 1: 5ms
Option 2: 20ms
Option 3: The value of T2 can be dynamically adjusted by the UE
Option 4: 10ms
Explanation: According to specifications for Rel-15 V2X sidelink communication, UEs supporting this feature must mandatorily support a minimum T2 value of 10ms for efficient resource selection in V2X sidelink communications, ensuring standardized and interoperable low-latency performance across all compliant devices, crucial for vehicular communication scenarios.
