During a 5G service test, an NSA UE connects to the Probe and then accesses a 4G cell. It is found that the cell does not deliver B1 measurement configurations. Which of the following is not a possible cause for this?
According to the official Huawei documentation, the possible causes for a 4G cell not delivering B1 measurement configurations during a 5G service test are that the UE does not support EN-DC, the NSA switch is not turned on, or neighboring LTE cells and SCGs are not configured.
During 5G single site verification, you only need to test the user access and rate. Other test items are analyzed in drive tests.
According to the official Huawei documentation, during 5G single site verification, you need to test the user access, rate, coverage, handover, and interference. Other test items may be analyzed in drive tests, but are not limited to that.
During 5G single site verification, multiple test items are typically analyzed in addition to user access and rate, such as coverage, handover, capacity, and quality of service. Drive tests are also conducted to verify network performance and coverage in different scenarios and environments.
Which of the following 5G massive MIMO scenarios is more suitable for high rise office building coverage?
H110V6 refers to a scenario where there are 110 horizontal and 6 vertical antenna elements installed on the gNodeB, which is ideal for providing coverage in high-rise office buildings. The high number of horizontal antenna elements allows for high-density deployment, which can improve the coverage and capacity of the network in these types of environments.
'H110V6 can be used to cover high-rise buildings, such as office buildings and hotels, which have complex indoor environments. The high number of horizontal antenna elements can provide strong coverage and capacity.' in Huawei official website.
Which of the following NR slot configurations are defined in 3GPP specifications? (Choose All that Apply)
1. 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.
Which of the following functions are implemented by the UBBP board in the BBU5900? (Choose all that Apply)
1. The UBBP board in the BBU5900 provides CPRI (Common Public Radio Interface) ports for communication with RF (Radio Frequency) modules. CPRI is an interface standard that is used to transfer baseband signal data between the BBU and the RF modules. D. The UBBP board also processes uplink and downlink baseband signals. This includes signal demodulation, decoding, and modulation, as well as error correction, signal filtering, and other signal processing functions.
