What are the common 5G NSA Mobility Common Handover failures Root-Causes? (1) Missing X2 Definition/Missing Neighbors * Unlike legacy 4G handover scenarios, where missing neighbors may cause quality issues or call drops but not affect the handover KPIs as the handover attempt will not be initiated at the first place

Did you know that 5G SRS can be configured with either a full-band SRS bandwidth or a narrow-band SRS bandwidth❓ - Purpose of SRS: Let's revisit the basics. SRS serves uplink channel measurement, time-frequency synchronization, and beam management. - Advantages and Disadvantages: So, what are the primary pros

What's 4G&5G Allocation and Retention Priority (ARP)? * Allocation and Retention Priority (ARP) in both 4G and 5G refers to the priority level assigned to a user or device within the network. * This priority determines how network resources are allocated and whether a connection is retained during
5G
What is T304 Timer? and How does the UE detect a Radio Link Failure based on this timer configuration ❓ * T304 Governs RRC Reconfiguration Procedure for the HO, Simply means that If the UE does not complete the handover before this timer expires, the UE reverts back to the associated configuration
5G
How does the UE detect a Radio Link Failure ❓ * Understanding this part is key, especially when troubleshooting or improving 4G & 5G retainability. It helps you know how the UE spots a radio link failure, which is vital for pinpointing issues. Plus, it gives you confidence when adjusting UE-related timers

Multi-User MIMO Brief Description: * UL MU-MIMO was introduced to take advantage of UE’s spatial isolation. * Uplink Multi-User MIMO Mid-Band enables uplink spatial multiplexing. In this way, extra PRBs are deployed throughout the entire network. Uplink spectrum efficiency is increased, hence uplink cell throughput is also increased * UL MU-MIMO supports
