Which of the following frequency locking modes is not supported when the GENEX Probe is used to perform a CPE test?
-"The following frequency locking modes are not supported when the GENEX Probe is used to perform a CPE test: PCI, Cell frequency" in Huawei official website.
Which of the following methods can be used to obtain VLAN IDs after a base station is powered on? (Choose All that Apply)
According to the Huawei SA Networking Product Design Guide (https://www.huawei.com/en/doc/e_huaweidoc/pdf/HW_051525), VLAN scanning is used to detect VLANs in a network. The VLAN scanning process is initiated on the base station and requires the base station to send a query to the Layer 2 switch. The query contains the VLAN ID, and the Layer 2 switch then responds with the list of interfaces that are associated with that VLAN ID. Configuration on the LMT is used to configure the VLAN and assign it to the base station. Finally, remote DHCP assignment is used to assign IP addresses to the base station from the DHCP server.
What is the maximum number of PCIs supported by a 5G network?
The maximum number of PCIs (Physical Cell Identifiers) supported by a 5G network is 1008. This is specified in 3GPP 5G standard TS 38.211, which states that the maximum number of PCIs that a 5G network can support is 1008.
In 5G, each cell is assigned a unique identifier called the PCI (Physical Cell Identity). The PCI is used to identify the cell and its system information, and it is used for various purposes such as cell selection, handover, and interference management.
According to 3GPP specifications, the maximum number of PCIs that can be supported by a 5G network is 1008, which allows for a large number of cells to be deployed in a network. However, the actual number of PCIs used in a network will depend on the specific deployment scenario, the network architecture, and the capacity requirements of the network.
In the inter-site DC solution, the X2 interface can be used to implement transmission interconnection between the LTE and NR sites. Which of the following is the requirement of the transmission delay in such case?
The X2 interface is a signaling interface used in LTE networks to interconnect two eNodeBs (LTE base stations) to support handover and other functions. In the inter-site DC solution, the X2 interface can also be used to implement the transmission interconnection between the LTE and NR sites.
In order to ensure smooth handover and service continuity between the LTE and NR sites, it is necessary to meet the requirement of low transmission delay, which is typically <20ms. This low delay requirement is important to ensure that the handover can be completed quickly and without interruption to the ongoing service.
