Question: In UTRAN Iur interface RNSAP signalling, when the standard range is insufficient, which IE is used as an alternative to indicate the maximum number of bits per MAC-e PDU for non-scheduled transmissions?
Option 1: Maximum Number of Bits per MAC-e PDU for Scheduled Transmission IE
Option 2: Extended Maximum Number of Bits per MAC-i PDU for Scheduled Transmission IE
Option 3: Extended Maximum Number of Bits per MAC-e PDU for Non-scheduled Transmission IE
Option 4: Standard Maximum Number of Bits per MAC-d Flow IE
Explanation: In scenarios where the standard range for the Maximum Number of Bits per MAC-e PDU for Non-scheduled Transmission is not sufficient, the protocol specifies an extended format to accommodate larger values. This ensures accurate communication of the maximum bit limit for non-scheduled transmissions in the UTRAN network, maintaining efficiency and control. The correct alternative for non-scheduled transmissions is thus the Extended Maximum Number of Bits per MAC-e PDU for Non-scheduled Transmission IE.
