Question: In E-UTRA, what does the `v2x-SupportedTxBandCombListPerBC-r14` field primarily indicate for a User Equipment (UE) regarding V2X sidelink communication?
Option 1: The maximum transmission power for V2X sidelink on specific band combinations.
Option 2: The UE's capability to prioritize V2X sidelink over EUTRA transmissions on shared bands.
Option 3: The supported band combinations where the UE can simultaneously transmit and receive EUTRA and V2X sidelink communications.
Option 4: The minimum required bandwidth for concurrent EUTRA and V2X sidelink operations on a single band.
Explanation: This option correctly interprets the field's purpose, highlighting its role in identifying band combinations where a UE can simultaneously handle both EUTRA (traditional cellular communications) and V2X sidelink (vehicle-to-everything) communications. This simultaneous capability is crucial for ensuring seamless connectivity while supporting safety-critical vehicular communications alongside regular cellular services.
