Quiz 1: Introduction to Data Encoding in 5G

Data Encoding in 5G

1. What are the three main usage scenarios of 5G that require improved throughput, latency, and reliability compared with a 4G system?

A. Enhanced mobile broadband (eMBB), ultra-reliable and low latency communications (URLLC), and massive machine type communications
B. Enhanced mobile broadband (eMBB), ultra-reliable and high latency communications (URHLC), and minimal machine type communications
C. Reduced mobile broadband (RMBB), ultra-reliable and low latency communications (URLLC), and massive machine type communications
D. Enhanced mobile broadband (eMBB), unreliable and low latency communications (ULLC), and massive machine type communications

2. Which encoding technique is used for user data in 5G networks and supports high throughput, a variable code rate and length, and hybrid automatic repeat request (HARQ)?

A. Polar Codes
B. High-Density Parity-Check (HDPC) codes
C. Low-Density Parity-Check (LDPC) codes
D. Medium-Density Parity-Check (MDPC) codes

3. Which encoding technique is used for control information in 5G networks and is designed to perform well with short block length while addressing a latency issue of successive cancellation decoding?

A. Polar Codes
B. High-Density Parity-Check (HDPC) codes
C. Low-Density Parity-Check (LDPC) codes
D. Medium-Density Parity-Check (MDPC) codes

4. What is the target throughput for 5G networks?

B. 20 Gbps
C. 30 Gbps
D. 40 Gbps

5. What is the role of Hybrid Automatic Repeat Request (HARQ) in 5G networks?

A. It increases the probability of retransmission, thereby increasing latency.
B. It reduces the probability of retransmission, thereby increasing latency.
C. It increases the probability of retransmission, thereby reducing latency.
D. It reduces the probability of retransmission, thereby reducing latency.
