5G NR pdcch-ConfigSIB1 – ControlResourceSetZero & SearchSpaceZero
In 5G, during initial network access, a UE does a completes a band scan for SSB decodes the PBCH. The PBCH provides sufficient information lo allow the UE to proceed […]
5G NR RSRQ Measurements and Its Mapping
The RSRQ (Referece Signal RecivedQuality) is a measurement performed by the UE to know the Quality of recieved Reference Signals. In 5G NR, RSRQ can be measurement for SS-Reference Siganls […]
5G SA Handover – Inter gNB-DU and Intra gNB-CU Handover
Mobility (Handover) in an important feature in any telecom generation and so it is in 5G. The basic handover procedure remains same as it was in legacy networks, i.e. UE […]
5G RAN and 5GC Network Slice Signaling
Network Slicing is considered as one of the key feature by 3GPP in 5G. A network slice can be looked as a logical end-to-end network that can be dynamically created. […]
5G NR NSA Mode: UE Network and Radio Capability Enquiry
In any wireless system, for accurate, efficient coordination and intercommunication base station must know the all capability about the UE. The base station enquires the UE Capability and UE report […]
5G NR-PDCCH Channel Overview and Processing
The physical downlink control channel (PDCCH) in NR carries Downlink Control Information (DCI). In this post we will understand how PDCCH operates by describing its physical layer structure, and the […]
5G NR SS-RSRP Value Measurement Mapping
UE does measurement of SS-RSRP and use it for cell selection, cell reselection, power control, mobility procedures and beam management procedures. RSRP measurement generated and reported at both Layer 1 […]
5G NR SCG Failure and Radio Link Failure
For the purpose of Radio Link Failure (RLF), the UE physical layer monitors the downlink radio link quality of the primary cell for indicating out-of-sync / in-sync status indications to […]
5G NR HO Setup: Handover Testing in Cabled Setup
Handover, or handoff in 5G NR or 4G LTE happens when a Data/Voice call is transferred from one cell to the an adjacent cell as the Mobile user moves through […]
5G NR NSA Network Access Issues and Possible Root Cause
Many of the operator across the global has started providing 5G services using NSA mode with Option 3.x . In NSA mode the network topology consist of a LTE cell, […]
