質問 # 24
In the context of mmWave deployments , what is the primary benefit of analog beamforming ?
正解：D
解説：
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.
質問 # 25
Which of the following statements about CBRA , or contention-based random access , is correct?
正解：D
解説：
The correct answer is B .
In contention-based random access , the UE chooses a random access preamble by itself from a configured pool of available contention-based preambles. This is typically used when the UE does not yet have a dedicated connection or when the network has not assigned a dedicated preamble.
Because multiple UEs may choose the same preamble at the same time, preamble collision is possible . That is why CBRA requires a contention resolution step.
Option C describes contention-free random access , not CBRA. In contention-free random access, the network assigns a dedicated preamble to the UE, so collision risk is avoided and contention resolution is not required.
Option A is not the correct CBRA principle being tested. RACH false detection can be a receiver/design issue, but it does not define the CBRA procedure.
Option D describes a possible NSA signaling behavior around access failure handling, but it is not the core correct definition of CBRA.
Therefore, the correct CBRA statement is:
The UE autonomously selects a preamble from the configured range and starts the random access procedure.
質問 # 26
A slice supporting sensors and smart meters would be categorized as:
正解：C
解説：
The correct answer is A .
Sensors and smart meters are typical massive IoT use cases. They usually involve a very large number of devices sending small amounts of data, often with low mobility and low power requirements.
This type of traffic fits mMTC , or massive Machine Type Communications .
Why the other options are not correct:
URLLC is used for very low-latency and highly reliable services, such as industrial automation, remote control, or mission-critical applications.
eMBB is used for high-throughput broadband services, such as video, fixed wireless access, or enhanced mobile internet.
DNN is not a slice category. It means Data Network Name and identifies the data network the UE connects to, similar to APN in LTE.
Therefore, a slice supporting sensors and smart meters is categorized as:
mMTC.
質問 # 27
What is the mandatory prerequisite to implement DSS , or Dynamic Spectrum Sharing ?
正解：B
解説：
The correct answer is D .
DSS allows LTE and 5G NR to share the same spectrum dynamically , instead of requiring a separate dedicated NR carrier. Therefore, dedicated NR spectrum is not mandatory. DSS is also not limited to TDD only; it is commonly used in FDD spectrum refarming scenarios as well. Public RAN references describe DSS as a mechanism where LTE and NR coexist in the same frequency band and share spectrum dynamically.
From an SRAN architecture point of view, the mandatory deployment condition is that the radio platform must support LTE and NR coexistence on the same radio resources. That requires RF module sharing or a DSS-capable shared radio configuration.
So the correct prerequisite is:
RF module sharing.
質問 # 28
Which of the following statements does not apply to mmWave radio propagation ?
正解：A
解説：
The correct answer is C .
At mmWave / FR2 frequencies , radio propagation is more challenging than in low-band or mid-band spectrum. Diffraction becomes weaker, blockage is more severe, foliage attenuation is high, and building penetration loss is significant. This is why mmWave networks usually require dense site grids, line-of-sight or near-line-of-sight paths, and strong beamforming. Industry mmWave references consistently describe high path loss, high penetration loss, and the need for directional antenna systems to compensate for these losses.
Option C does not apply because water absorption and atmospheric absorption generally become more relevant at higher frequencies, not lower. Rain, humidity, and oxygen/water-vapor absorption are important considerations for mmWave link budgets.
So the statement that does not apply to mmWave propagation is:
Low water absorption at high frequencies.
