Question: In E-UTRA RRC protocol, when adding non-critical extensions to a message that has already been critically extended, what is the recommended approach regarding their inclusion in earlier critical branches of the message?
Option 1: Always include them in the earliest possible branch for consistency.
Option 2: Avoid including them in earlier critical branches when possible.
Option 3: Place them in a separate section to differentiate from critical extensions.
Option 4: Require a length determinant for all non-critical extensions regardless of placement.
Explanation: This approach minimizes potential impacts on the processing of critical branches, ensuring that earlier defined critical functionalities remain unaffected by later non-critical additions. This aligns with the principle of minimizing disruptions to established, critically extended message structures in E-UTRA RRC protocol specifications.
