H35-480_V3.0 Sample Questions Answers

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 the official Huawei documentation, during a 5G test, a portable computer can be directly connected to the LAN port of the Huawei CPE through a network cable to obtain a dynamic IP address for communication.

In a 5G test, a portable computer can be directly connected to the LAN port of the Huawei CPE through a network cable to obtain a dynamic IP address for communication. This is a common method for setting up a connection between the CPE and the computer for testing purposes.

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.

According to the official Huawei documentation, the first message sent by a gNodeB to an AMF is NGAP_INIT_UE_MSG. This message is used to initiate a connection between the gNodeB and AMF.

A. DM-RS (Demodulation Reference Signals) are transmitted in the frequency domain, they are used to demodulate the downlink data and control channels, and they can be used for cell measurement such as cell identification, cell reselection, and handover. B. CSI-RS (Channel State Information Reference Signals) are also transmitted in the frequency domain, they are used to provide channel state information for downlink data and control channels, and they can be used for cell measurement such as link adaptation, beamforming and interference management.

DM-RS stands for Demodulation Reference Signal and is used for channel estimation in the frequency domain. CSI-RS stands for Channel State Information Reference Signal and is used for channel estimation in the time-frequency domain. PT-RS and SSB are not channels (signals) that can be used for cell measurement in NR.

A. Mixed slot is a slot configuration in which at least one downlink/uplink symbol is present, while other symbols can be flexibly configured for downlink or uplink transmission. This allows for a more efficient use of resources and better support for different types of services. B. Flexible-slot is a slot configuration in which all symbols are flexibly configured for downlink or uplink transmission. This allows for a more efficient use of resources and better support for different types of services. C. Downlink-only slot is a slot configuration in which all symbols are dedicated for downlink transmission, This configuration is mainly used for downlink-centric services such as video streaming or software downloads. D. Uplink-only slot is a slot configuration in which all symbols are dedicated for uplink transmission, this configuration is mainly used for uplink-centric services such as voice calls or video conferencing.
