Which of the following descriptions about the parameter configuration of NG-RAN to E-UTRAN handover is incorrect?
- A . The inter-system service mobility algorithm switch needs to be turned on
- B . Switching methods include switching and redirection
- C . The lower the 4G frequency band, the lower the priority of the recommended connection state frequency
- D . Can support switching and redirection at the same time
Which of the following functions does ANR self-optimization include? (Multiple choice)
- A . NR cross-zone identification
- B . Automatically delete neighboring areas
- C . NR Overlapping Identification
- D . Automatically add neighboring areas
The protocol stipulates that the judgment formula for cell selection is "Srx1ev>0 and Squal>0 and Ssinr>0
- A . True
- B . False
Which of the following descriptions about the penalty for switching failure is wrong?
- A . Penalties for handover preparation failure are divided into resource-based and non-resource-based penalties.
- B . Resource failure reasons, by setting a penalty timer to limit switching retries
- C . If the UE fails to switch to the target cell more than 2 times, it will not initiate a handover to the target cell again.
- D . Non-resource failure reasons, limit UE switching retries by the number of penalties
Which of the following conditions must be met for Huawei NR cell reselection of cells with different frequencies and the same priority level? (Multiple choice)
- A . Satisfy the cell selection rules
- B . The RSRP difference with the strongest neighboring cell is less than or equal to 3dB
- C . The largest number of beams
- D . Satisfy the cell reselection R rule
Which of the following descriptions of the MCS selection algorithm in downlink scheduling are correct? (Multiple choice)
- A . The initial MCS is calculated by mapping the CQI
- B . To avoid the impact of untimely CQI reporting , the base station will also adjust the MCS based on the IBLER measurement.
- C . MCS selection needs to consider cache size
- D . MCS selection needs to consider terminal capabilities
Which of the following descriptions of QoS parameters are correct? (Multiple choice)
- A . In SA scenario, 5GC directly sends the data through the N2 interface
- B . QoS parameters come from the UE’s SIM card
- C . The UE’s y service rate will remain unchanged under QoS control
- D . In the NSA scenario, the eNB sends the data through the X2-C interface and the gNB performs the mapping.
Which of the following are correct descriptions of 5G CU/DU separation? (Multiple choice)
- A . After CU/DU is separated, higher reliability requirements are required to avoid single point failures
- B . RAN-CU functions are centrally deployed in the cloud, with better DC, traffic distribution, edge computing, and intelligent operation and maintenance
- C . Placing the CU in the data center can achieve a wider range of control processing, resource sharing and lower latency
- D . Placing the CU in the aggregation room has the disadvantage that resources cannot be shared on a large scale, and the room may need to be renovated to deploy COTS servers.
Which of the following factors will cause the RRC establishment failure reason value to be RRC NoReply?
- A . UE sent MSG5, and the base station failed to demodulate
- B . UE did not send MSG3
- C . UE did not receive MSG4
- D . UE did not send MSG5
In which of the following scenarios will Huawei’s base station scheduling algorithm obtain a higher scheduling priority? (Multiple choice)
- A . Historical transmission rate is high
- B . The larger the business weighting factor, the
- C . The data packet waits for a long time in the cache.
- D . User channel quality is good
