HCS-5G RF Advanced V1.0 H35-462 Exam Dumps

1. The length of TTI scheduled in 5G NR is 1 slot.

2. In NSA networking 0ption3X scenario, the SIB broadcast message content of 5G cell is sent to UE through 4G cell.

3. The electrical-tunable antenna refers to adjusting the phase of the antenna element through electrical signals, changing the signals of the horizontal component and the vertical component, thereby changing the coverage distance of the antenna.

4. The Ss channel power of the NR cell will be dynamically adjusted according to the actual environment.

5. In the 5G network, for the sake of user security, the NsA layer uses 5G-GUTI to replace IMSI as the user's temporary ID.

6. The relevant configuration parameters of sRs in NR are only user-level, not cell-level.

7. The NR standard supports that the PDCCH channel occupies up to 3 symbols in the time domain.

8. The purpose of PRACH power control is to guarantee the success rate of NR random access, the UE transmits the preamble with as little power as possible, to reduce the interference to the neighboring cell and to save power for the UE.

9. In the NSA networking, NR will be recorded on the 5G network side when call drop.

10. NR uses A3 event to trigger PSCe11 change.

11. The secondary cell change in the SgNB station uses the SBNB Modification process.

12. The scheduling priority of retransmission data is higher than that of the initial transmission data.

13. The scheduling function of the NR network is mainly implemented at the RRC layer.

14. SRS power control is mainly used for uplink channel estimation and uplink timing to ensure its accuracy.

15. The principle of NR system coverage problem optimization is to first optimize SS SINR, then optimize SS RSRP.

16. In the NSA networking, the secondary station release ratio is too high due to poor NR coverage.

17. When PScel1 fails to change, the UE will perform the RRC reconstruction process.

18. The bandwidth of one CCE in NR is 3 RBs.

19. When the UE under the NSA architecture attaches to the network, it can directly attach to the NR network.

20. The modulation methods of PUCCH and PDCCH channels in NR are both QPSK.
