Which of the following Information Is contained in a master Information block (MIB)?
- A. PDCCH ConfigSIB1
- B. System frame number
- C. Offset from PointA
- D. dmrs-TypeA-Position
Answer: A,B,D
Explanation:
In 5G NR, the master information block (MIB) is a control message that is transmitted by the base station on the Physical Broadcast Channel (PBCH). The MIB contains the following information:
1. System frame number: The MIB contains the system frame number (SFN) which is used to identify the current frame in the system.
2. PDCCH ConfigSIB1: The MIB contains the PDCCH (Physical Downlink Control Channel) configuration for the SIB1 (System Information Block 1) which is used to transmit system information to the UE.
3. dmrs-TypeA-Position: The MIB contains the position of the dmrs-TypeA (Diversity and Multiplexing Configuration Reference Signal) which is used to transmit a reference signal for demodulation and channel estimation.
NEW QUESTION # 31
Which of the following statements about PDSCH DMR5 is incorrect?
- A. The front-loaded DMRS is mandatory, and the additional DMRS is optional.
- B. The overhead of type 1 DMRS is less than that of type 2 DMRS.
- C. The start symbol of a front-loaded DMRS of a type A PDSCH can be symbol 2.
- D. The start symbol of a front-loaded DMRS of a type B PDSCH is always the first symbol of PDSCH.
Answer: D
Explanation:
The statement "The start symbol of a front-loaded DMRS of a type B PDSCH is always the first symbol of PDSCH" is incorrect. In 5G NR, the start symbol of a front-loaded DMRS of a type B PDSCH can be configured as the first symbol of PDSCH or as the second symbol of PDSCH.
You can refer to the Huawei official documentation for HCIP-5G-RAN V2.0 certification and the 3GPP 5G NR standard (38.211, 38.212, 38.213) for more information on PDSCH DMRS, including the configurations of the front-loaded DMRS, the DMRS symbols and the optional and mandatory nature of it.
