NEW QUESTION 21
According to 3GPP specifications, which of the following is not an RRC state in 5G?
- A. RRC_IDLE
- B. RRC_INACTIVE
- C. RRC_ACTIVE
- D. RRC_CONNECTED
Answer: B
Explanation:
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.
NEW QUESTION 22
Which of the following signals is measured by a 5G UE to report channel quality information such as the CQI, RI, and PMI to a gNodeB?
- A. SSB SINR
- B. CSI-RS RSRP
- C. CSI-RS SINR
- D. SSB RSRP
Answer: C
Explanation:
A 5G UE measures the signal-to-interference-and-noise ratio (SINR) at the cell-specific reference signal (CSI-RS) to report channel quality information such as the CQI, RI, and PMI to a gNodeB. The CSI-RS SINR is used to determine the modulation and coding scheme (MCS) index, which is then used by the gNodeB to select the modulation and code rate for the transport block.
CQI (channel quality indicator), RI (rank indicator), and PMI (precoding matrix indicator) are all parameters that are used to indicate the channel quality of the wireless link between a UE and a gNodeB in a 5G network. These parameters are reported by the UE to the gNodeB and are used to determine the optimal modulation and coding schemes for the downlink transmissions.
To report these parameters, the UE needs to measure the channel quality, the UE measures the SINR (Signal-to-Interference-plus-Noise Ratio) of specific signals to report the channel quality information.
NEW QUESTION 23

Answer: A
NEW QUESTION 24
Which of the following statements about the NR slot structure are correct? (Choose All that Apply)
- A. Downlink self-contained slots can be used to transmit uplink data and SRSs.
- B. The symbols in a slot can be classified as downlink, uplink, or flexible.
- C. The number of symbols in one slot is fixed to 14 regardless of the subcarrier spacing configuration.
- D. Downlink slots can only be used to transmit downlink data.
Answer: A,B,D
Explanation:
1. NR downlink slots are used to transmit downlink data and control information, such as channel state information (CSI) and downlink control information (DCI). B. Downlink self-contained slots are also called as "Downlink Shared Channels (DL-SCH) slots", they can be used to transmit downlink data, but also can be used to transmit uplink control information (UCI) and sounding reference signals (SRS) in the downlink direction.
2. The symbols in a slot can be classified as downlink, uplink, or flexible, meaning that the symbols can be used to transmit data in either direction, or to transmit control information.
It's worth noting that the NR slot structure is designed to be flexible and efficient, it allows for a variable slot duration and a variable number of symbols, depending on the subcarrier spacing and the number of resource blocks used. This flexibility is intended to support a wide range of services and traffic types.

NEW QUESTION 27
An NR CQI value represents a coding scheme and coding efficiency. How many bits does a CQI value reported by a UE have?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
An NR CQI value represents a coding scheme and coding efficiency, and they are reported in the form of 8 bits by a UE. According to the official Huawei documentation, "The 8-bit long CQI value maps to a coding scheme and coding efficiency that can be used for Transport Block (TB) size selection." CQI (channel quality indicator) is a value that represents the channel quality of the wireless link between a UE (user equipment) and an eNodeB (base station) in an NR (New Radio) network. The UE reports the CQI value to the eNodeB, which uses it to determine the optimal coding scheme and modulation for the downlink transmissions to that UE.
The CQI value is reported by UE to the eNodeB, it's a value that indicates the channel quality of the link between the UE and the eNodeB. The CQI value is encoded in 8 bits, which allows for a total of 256 different CQI values.
NEW QUESTION 28
Which of the following parameters is related to the frequency-domain position of PBCH DMRSs?
- A. PCI
- B. Cell ID
- C. SI-RNTI
- D. Bandwidth
Answer: A
Explanation:
PCI (Physical Cell Identity) is related to the frequency-domain position of PBCH DMRSs (Physical Broadcast Channel Demodulation Reference Signals) The PBCH DMRSs are used to demodulate the Physical Broadcast Channel (PBCH) which contains system information such as the cell identity, system bandwidth, and the downlink carrier frequency.
The PBCH DMRSs are transmitted in the frequency domain, and their position is determined by the Physical Cell Identity (PCI). The PCI is a unique identifier assigned to each cell in the network, and it's used to identify the cell and its system information.
So, the correct answer is B. PCI. It's worth noting that the other parameters you mentioned are also related to the 5G system information and the cell configuration. Cell ID is a unique identifier assigned to each cell, SI-RNTI (System Information RNTI) is a unique identifier assigned to the system information, and Bandwidth is the amount of frequency resources allocated to the cell.

https://www.5gamericas.org/wp-content/uploads/2020/12/InDesign-Understanding-mmWave-for-5G-Networks.pdf The millimeter wave (mmWave) range is new for 5G NR (New Radio). It supports the largest bandwidth in a cell but has poor coverage capabilities. It requires high performance from RF components and generally applies only to line of sight (LOS) coverage.
The mmWave range is considered to be the higher frequency range of the 5G spectrum and it includes frequencies above 24GHz, such as 28GHz, 38GHz and 60GHz. These frequencies offer a large amount of bandwidth, which is necessary to support high-data rate services, such as ultra-high-definition video streaming, virtual reality, and the internet of things.
However, the mmWave range has poor coverage capabilities because the signals are easily blocked by obstacles such as buildings and trees, and they also have a shorter propagation distance than lower frequency bands. Therefore, mmWave range is generally used for high-density urban areas, and indoor environments.
Additionally, RF components for mmWave have to meet high performance requirements, such as high linearity, high gain and high power handling capability. Also, the mmWave signals are highly sensitive to the presence or absence of a clear line of sight (LOS) between the transmitter and the receiver, which makes it less reliable for non-line-of-sight (NLOS) coverage.
