Question: In E-UTRA downlink physical-layer processing for transport channels, what type of channel coding is specifically used for NPDSCH (Non-Priority Data Shared Channel)?
Option 1: Turbo coding with QPP inner interleaving and trellis termination
Option 2: Tail Biting Convolutional Coding and Reed-Solomon Coding
Option 3: Tail Biting Convolutional Coding
Option 4: LDPC (Low-Density Parity-Check) Coding
Explanation: According to the specified downlink physical-layer processing steps for E-UTRA transport channels, NPDSCH employs Tail Biting Convolutional Coding for channel coding, distinguishing it from PDSCH which uses Turbo coding based on QPP inner interleaving with trellis termination. This highlights the adaptation of different coding schemes for various types of data transmissions in telecom networks to optimize reliability and efficiency.
