Question No. 2

According to 3GPP specifications, which of the following is not an RRC state in 5G?

Show Answer Hide Answer
Correct Answer: D

According to 3GPP specifications, the RRC states in 5G are RRCIDLE, RRCACTIVE, and RRCCONNECTED. RRCINACTIVE is not an RRC state defined in 3GPP specifications. RRCIDLE is the state when the UE is not attached to an eNB and is not actively monitoring for paging. RRCACTIVE is the state when the UE is attached to an eNB and is actively monitoring for paging. RRCCONNECTED is the state when the UE has an established RRC connection with an eNB.

The RRC is a protocol that controls the radio resources of the mobile device in a cellular network. 3GPP (3rd Generation Partnership Project) has defined several RRC states for 5G NR (New Radio) to manage the radio resources of the mobile device. These states are:

1. RRC_IDLE: The mobile device is not connected to any cell and is not actively searching for a cell to connect to. B. RRC_ACTIVE: The mobile device is connected to a cell and is actively communicating with it. C. RRC_CONNECTED: The mobile device is connected to a cell, but it's not actively communicating with it. It is in a low power state and is only listening to the paging channel for incoming calls or data.

So, the correct answer is D. RRC_INACTIVE, is not an RRC state in 5G according to 3GPP specifications. It's worth noting that the RRC state of the mobile device can change dynamically based on the network conditions, service requirements, and the mobile device's power management.


Question No. 4

The RSRP value of the test terminal can be viewed on the GENEX Probe. Which of the following test results indicate good signal quality?

Show Answer Hide Answer
Correct Answer: B

'The RSRP value of the test terminal can be viewed on the GENEX Probe. A RSRP value of between -60dBm and -90dBm indicates good signal quality. Lower values indicate weaker signals, while higher values indicate stronger signals.'


Question No. 5

F-OFDM over the NR air interface uses flexible subcarrier spacing to meet the requirements of different 5G service scenarios. Which of the following types of subcarrier spacing is not supported by Sub6G?

Show Answer Hide Answer
Correct Answer: A

F-OFDM (Filtered Orthogonal Frequency Division Multiplexing) over the NR air interface uses flexible subcarrier spacing to meet the requirements of different 5G service scenarios. F-OFDM is a 5G physical layer waveform that is designed to provide high spectral efficiency, low complexity and low latency. It uses a flexible subcarrier spacing, which can be adjusted to meet the requirements of different 5G services. The subcarrier spacing can be 15KHz, 30KHz, 60KHz, or 120KHz.

Sub-6GHz 5G networks are designed to provide wide-area coverage and support high data rate services such as mobile broadband, IoT, and critical communications. Sub-6GHz band is mainly used for 5G deployment in rural areas, and in-building coverage.

Therefore, the subcarrier spacing that is not supported by Sub-6GHz is 120KHz. So the correct answer is A. 120KHz. It's worth noting that each subcarrier spacing has its own advantages and disadvantages. 120KHz spacing is mainly used for low mobility services such as fixed wireless access, while 15KHz spacing is mainly used for high mobility services such as mobile broadband.
