Question: What is implied if a User Equipment (UE) indicates support for sidelink communication on at least one band in its commSupportedBands-r12 field?
Option 1: The UE only supports sidelink reception, not transmission.
Option 2: The UE must support up to 8 sidelink processes for SL-SCH reception.
Option 3: The UE is limited to eNB scheduled resource allocation for sidelink.
Option 4: The UE shall support both UE autonomous resource selection and eNB scheduled resource allocation for sidelink transmission, among other capabilities.
Explanation: According to the specifications, if a UE supports sidelink communication on at least one band, it implies comprehensive support, including both UE autonomous resource selection and eNB scheduled resource allocation for transmission, as well as ProSe Per Packet Priority (PPPP) handling and out of coverage sidelink discovery. This ensures versatile operation in various scenarios, highlighting the importance of flexible resource management in sidelink communications within telecom networks.
