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 RSRP
- B. SSB SINR
- C. CSI-RS RSRP
- D. CSI-RS SINR
Answer: D
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.

D. Uplink-only slot is a slot configuration in which all symbols are dedicated for uplink transmission, this configuration is mainly used for uplink-centric services such as voice calls or video conferencing.
NEW QUESTION # 25
At which layer is downlink data split implemented over the NR air interface in the NSA Option 3x architecture?
- A. Physical layer
- B. MAC layer
- C. PDCP layer
- D. RLC layer
Answer: B
Explanation:
Downlink data split over the NR air interface in the NSA Option 3x architecture is implemented at the medium access control (MAC) layer. The MAC layer is responsible for the management of data transmission over the air interface, including segmentation and reassembly of data packets, scheduling of transmission resources, and error correction. The other layers (RLC, PDCP, and physical) are not involved in the implementation of downlink data split.

In the Non-Stand-Alone (NSA) Option 3x architecture, the control plane functions are handled by the 4G LTE network (EPC), while the user plane functions are handled by the 5G NR network. Data split is a technique that allows to split the user plane data between the 4G LTE and 5G NR networks.
The MAC (Medium Access Control) layer is responsible for controlling the access to the shared wireless medium, and it is where the downlink data split is implemented. In this architecture, the MAC layer in the 5G NR network receives the downlink data from the 4G LTE network and sends it to the physical layer for transmission.

NEW QUESTION # 30
The mmWave range is new for NR. 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.
- A. True
- B. False
Answer: A
Explanation:
The mmWave range is a new spectrum range for 5G NR, and it supports the largest bandwidth in a cell. However, it has poor coverage capabilities, as it requires high performance from RF components and generally applies only to line of sight (LOS) coverage. This makes it challenging to use in many applications, as it requires careful planning and implementation in order to ensure effective coverage.

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.
