Question: In 5G NR (New Radio) as per 3GPP specifications, what determines the initialization value for the second m-sequence (`c`) in a length-31 Gold sequence used for pseudo-random sequence generation?
Option 1: The length of the output sequence (`n`)
Option 2: A fixed value defined universally across all applications
Option 3: The specific application of the pseudo-random sequence
Option 4: The first m-sequence's initialization value (`x`)
Explanation: The correct answer is Option 3 because, according to the specifications, the initialization of the second m-sequence (`c`) is denoted by `c_init` with its value **depending on the application** of the sequence. This implies that different applications may require different initializations for the second m-sequence, highlighting the importance of application-specific configuration in pseudo-random sequence generation for 5G NR.
