Question: In UTRAN Iur interface RNSAP signalling, how many bits are used by default to code 3 TFCI (Transport Format Combination Indicator) bits?
Option 1: 8 bits
Option 2: 16 bits
Option 3: 24 bits
Option 4: 32 bits
Explanation: According to the TFCI Coding rules in UTRAN Iur interface RNSAP signalling, by default, 3 to 5 TFCI bits are coded with 16 bits. This efficient coding scheme allows for the transmission of multiple TFCI bits within a standardized bit length, facilitating effective radio resource management and communication between network elements.
