According to the 5G mmWave Frequency Bands, the maximum bandwidth in mmWave bands as defined in 3GPP Release 16 is 400MHz, which can be achieved without any carrier aggregation method.
Question 2
Which of the following boards support CPU usage query?(Select All that Apply)
Options:
A.
FAN
B.
UPEU
C.
UMPT
D.
UBBP
Answer:
B, C, D
Explanation:
Explanation:
According to the Huawei 5G Base Station Product Description, the following boards support CPU usage query:
UPEU (Universal Power and Environment Interface Unit): It provides power supply and environment monitoring functions for other boards in a subrack. It supports CPU usage query through commands or web pages.
UMPT (Universal Main Processing and Transmission Unit): It provides main processing and transmission functions for a subrack. It supports CPU usage query through commands or web pages.
UBBP (Universal Baseband Processing Unit): It provides baseband processing functions for a subrack. It supports CPU usage query through commands or web pages.
The FAN (Fan Unit) does not support CPU usage query because it does not have a CPU.
Question 3
Which of the following channels/signals is used by the UE to measure and obtain the CQI?
Options:
A.
PDSCH
B.
OSSB
C.
CSI-RS
D.
PDCCH
Answer:
C
Explanation:
Explanation:
According to the 5G NR Downlink CSI Reporting, CSI-RS is the channel/signal that is used by the UE to measure and obtain the CQI. CSI-RS stands for Channel State Information Reference Signal, which is a downlink reference signal transmitted by the gNodeB to enable the UE to estimate the channel quality and feedback the CQI to the gNodeB. The CQI is an indicator of how good or bad the channel quality is, and it can be used by the gNodeB to adjust the modulation and coding scheme for data transmission.
