To support the Multi-Vendor connectivity, 3GPP studied the “CU-DU Split” Function, So What is CU and DU? Centralized RAN architectures have a baseband unit (BBU) that handles all baseband processing […]

To synchronize with the cell and decode the Master Information Block (MIB), UE has to decode the SSB block which consists of PSS, SSS, PBCH, and PBCH DMRS. The SS […]

Option 2 allows 5G deployments in areas without 4G coverage but there will be many areas where only LTE or 3G can be used. Voice calls, which start in 5G, […]

As 5G Resource Block (RB) concept is different than LTE as 5G RB is one-dimensional only (i.e. Frequency domain) only. 5G NR is 12 consecutive subcarriers in the frequency domain. […]

IMS Support for SA Option 2 and Voice over NR When 3GPP defined 5G in 3GPP Release 15 (Rel-15), the impact on IMS was minimized to assist with 5G deployment. […]

gNB: is the next-generation base station in 5G.

Thanks for your question, I am happy to summarize all my knowledge-sharing channels as below:  Moniem-tech Website. Mohamed Abdel Monem Linkedin Profile Moniem-tech Linkedin Page. Moniem Education Youtube Channel. Moniem-tech […]

In simple words, I prepared this chart.

Cloud-Native computing uses an open-source software stack to deploy applications as microservices, packaging each part into its own container, and dynamically orchestrating those containers to optimize resource utilization. Cloud-native technologies […]

Yes, this is an interesting question, as per the VoLTE call procedure the UE MUST register in IMS to can get Radio access bearer or QCI=5 to can make the […]

IAB: It stands for Integrated Access and Backhaul, It supports wireless backhaul and relay links in-band or out-of-band with access links. Significant 5G NR bandwidth can be split between access […]
