H35-480_V3.0 Questions and Answers

Static power control is used to adjust the transmission power of UEs to meet the requirements of cell-edge UEs, while dynamic power control is used to adjust the transmission power of UEs to meet the requirements of the uplink channel quality. PUSCH is the channel used by the UE to transmit data to the gNodeB and supports both static and dynamic power control.

The imbalance between uplink and downlink coverage in C-band is not fixed, it varies depending on the network configuration, location, and other factors. Generally speaking, it's hard to provide an exact number for this imbalance, as it depends on the specific network conditions and the equipment used.

However, a common practice is to use more power in downlink than uplink, this is due to the fact that downlink is more sensitive to path loss than uplink, and also because the downlink signal is intended to cover a larger area than the uplink. Therefore, the imbalance is commonly in the range of 3 to 6 dB, and it's more likely to be at the lower end of that range. So, the correct answer is B. 3dB It's worth noting that the C-band is not the most popular frequency band for 5G network deployment, it's just one of the many frequency bands that are being used for 5G deployment, and the most popular frequency bands for 5G deployment vary depending on the country, region, and operator.

According to 5G eMBB service requirements, the minimum rate required for network edge coverage is 100Mbps.

Control subsystem: It is responsible for managing and controlling the overall operation of the BBU, it provides functions such as system initialization, software management, and alarm management.

Transmission subsystem: It is responsible for the transmission of data between the baseband subsystem and the RF subsystem, it includes functions such as data encoding, modulation, and multiplexing.

Baseband subsystem: It performs the baseband processing for the BBU, it includes functions such as demodulation, decoding, and demultiplexing.
