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-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 […]
