Question: Which of the following is NOT a primary function of the Physical Uplink Shared Channel (PUSCH) in relation to the information it carries from higher layers in a 5G NR (New Radio) uplink transmission?
Option 1: To transmit user data and higher-layer signaling to the gNB (Next-Generation Node Base).
Option 2: To primarily carry synchronization signals for initial access to the network.
Option 3: To convey control information such as channel state feedback and hybrid ARQ acknowledgments.
Option 4: To support the transmission of broadcast and multicast services from the network.
Explanation: The primary function of PUSCH is to carry user data, higher-layer signaling (e.g., RRC, MAC), and control information like channel state feedback and hybrid ARQ acknowledgments. Synchronization signals for initial access are primarily associated with the Physical Random Access Channel (PRACH), not PUSCH. Thus, Option 2 describes a function NOT primarily attributed to PUSCH, making it the correct answer.
