Question: In UTRAN Iur interface RNSAP signalling, what is a key characteristic of the Transport Format Set associated with a specific Transport Channel, such as a Dedicated Channel (DCH)?
Option 1: The Transport Format Set can vary dynamically based on real-time network congestion for each DCH.
Option 2: The Transport Format Set is defined as a single, unchanging transport format per Transport Channel.
Option 3: The Transport Format Set comprises multiple Transport Formats, all associated with the same Transport Channel (e.g., DCH).
Option 4: The Transport Format Set is exclusively determined by the User Equipment's (UE) capabilities.
Explanation: This answer correctly reflects that a Transport Format Set encompasses multiple Transport Formats all linked to the same Transport Channel, crucial for managing and optimizing data transmission in UTRAN networks.
