Question: In 5G New Radio (NR) channel coding, what is the primary coding scheme employed for encoding information bits, denoted as **a** with a length of **K**, to produce coded bits denoted as **c** with a length of **N**?
Option 1: Convolutional Coding with Viterbi Decoding
Option 2: Polar Coding
Option 3: Low-Density Parity-Check (LDPC) Coding
Option 4: Turbo Coding with Trellis Termination
Explanation: In the context of 5G NR channel coding for information bit transmission, Polar Coding is specifically utilized. This method efficiently encodes information bits (**a**, length **K**) into coded bits (**c**, length **N**), adhering to detailed parameter settings, making it the correct choice for this scenario.
