According to the NR-ARFCN (NR absolute radio frequency channel number), the NR-ARFCN value consists of two components: the band indicator and the channel number. The band indicator represents the frequency band on which the carrier frequency lies, while the channel number represents the specific carrier frequency within that band. The NR-ARFCN value is calculated by the following formula:

NR-ARFCN = FREF-Offs + NREF-Offs + ΔFGlobal * (Fcarrier - FREF-Offs) / AFGIobal

where FREF-Offs is the reference frequency offset, NREF-Offs is the reference NR-ARFCN offset, ΔFGlobal is the global frequency raster, Fcarrier is the carrier frequency, and AFGIobal is the absolute frequency granularity.

Given that AFGIobal is 15 kHz, FREF-Offs is 3000 MHz, and NREF-Offs is 600000, we can plug in these values and Fcarrier = 3300 MHz into the formula and get:

NR-ARFCN = 3000 + 600000 + 5 * (3300 - 3000) / 0.015 NR-ARFCN = 633000

Therefore, the correct answer is A.

According to the 5G NR Physical Layer Specifications, demodulation reference signals (DMRSs) are required for the following channels/signals in the downlink and uplink:

• Downlink Physical Broadcast Channel (DPBCH)
• Downlink Physical Downlink Control Channel (DPDCCH)
• Downlink Physical Shared Channel (DPOSCH)
• Uplink Physical Random Access Channel (PRACH)
• Uplink Physical Uplink Control Channel (PUCCH)
• Uplink Physical Uplink Shared Channel (PUSCH)

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.
