질문 # 16
In the context of mmWave deployments , what is the primary benefit of analog beamforming ?
정답：B
설명：
The correct answer is A .
In mmWave systems, beamforming is essential because FR2 signals suffer from high path loss and blockage.
Analog beamforming uses fewer RF chains than fully digital beamforming, so it is cheaper and less complex in terms of RF hardware, power consumption, and implementation. Research and industry references explain that analog and hybrid beamforming architectures reduce the number of required ADCs/RF chains compared with fully digital beamforming, lowering cost and power complexity.
However, analog beamforming has limitations. It usually forms one beam, or a limited number of beams, at a time from a panel. Supporting multiple independent simultaneous beams and more UEs per sector is more associated with digital or hybrid beamforming, not pure analog beamforming.
Therefore, the primary benefit is:
Low cost and low complexity for coverage at higher mmWave bands.
질문 # 17
Identify the missing network components X, Y, and Z in the architecture diagram.
정답：C
설명：
The correct answer is B .
In the 5G Core , component X is connected to:
N2 from NG-RAN
N11 toward SMF
N15 toward PCF
N26 toward the EPC mobility entity
These are typical interfaces of the AMF , or Access and Mobility Management Function . Therefore, X = AMF .
In the EPC , component Z is connected to:
S1-MME from eNB
S11 toward the gateway
N26 toward the 5GC AMF
These are typical interfaces of the MME , or Mobility Management Entity . Therefore, Z = MME .
Component Y is outside the core user-plane path and represents the external service network connected through N6/SGi , commonly shown as IMS in voice-service architecture diagrams. Therefore, Y = IMS .
So the correct mapping is:
X: AMF, Y: IMS, Z: MME.
질문 # 18
Evaluate the impact of extended FR2 cell range on power consumption.
정답：D
설명：
The correct answer is C .
In FR2/mmWave , uplink coverage is often the limiting factor because UE transmit power is much lower than gNodeB transmit power, and mmWave propagation suffers from high path loss and blockage. Ericsson's mmWave coverage discussion also notes that high-band coverage is limited by uplink signal quality and high- band propagation characteristics.
When the FR2 cell range is extended, UEs farther from the serving cell must transmit uplink signals over a more difficult radio path. This usually requires higher UE transmit power, more robust MCS, more repetitions or retransmissions, and potentially longer uplink activity. As a result, UE battery consumption can increase.
Therefore, extended FR2 range generally:
Increases power consumption because UEs need more energy to transmit uplink signals.
질문 # 19
At which mark are all conditions fulfilled for energy saving , so the cell will be switched off? Refer to the image below.
정답：A
설명：
The correct answer is B , which corresponds to mark C in the diagram.
In the diagram, the energy-saving process follows these stages:
Before mark B , the cell is entering the power-saving period, but the required load condition has not yet been satisfied for the required duration.
At mark B , the measured load has gone below the configured threshold, but the cell is not switched off immediately. The system must confirm that the load remains below the required threshold for the configured time.
At mark C , the load has stayed below the required threshold for the required duration, shown as 5 minutes in the diagram. At this point, all conditions are fulfilled, and the cell can be switched off. The diagram also shows the state becoming:
energySavingState = energySaving
Marks D and E are already inside or near the later part of the power-saving period. Mark E is associated with operator suspension/exit behavior, not the initial moment when all switch-off conditions are first fulfilled.
질문 # 20
Choose the correct statement from the options below.
정답：B
설명：
The correct answer is B .
Beamforming is mainly about shaping and directing radio energy toward a UE or a target area. It improves coverage, SINR, and cell-edge performance by focusing the transmitted or received signal in a specific direction.
MIMO , or Multiple Input Multiple Output , uses multiple antenna paths to improve throughput, reliability, and spectral efficiency. MIMO can be used for spatial multiplexing, diversity, or beamforming depending on the antenna system and radio configuration.
Option A is incorrect because beamforming and MIMO are related but not the same.
Option C reverses the definitions.
Option D is incorrect because beamforming and MIMO are commonly used together, especially in Massive MIMO systems.
So the correct statement is:
Beamforming focuses on directing the signal, while MIMO focuses on utilizing multiple paths for data transmission.
