5G SON – Automatic Neighbor Relations – ANR
Introduction In old days, 2G and 3G Cellular systems configurations were based on information from planning tools and drive tests. With the development of 4G LTE, the Service Providers put […]
5G MSG3 – PUSCH Scheduled Transmission by RAR UL grant
Introduction When we want to connect a UE to 5G network, it has to synchronize in downlink as well as in uplink. Downlink synchronization is obtained after successfully decoding SSB, […]
Radio Link Monitoring in 5G – RLM
Introduction When a UE is connected to the network, it requires to continuously monitor the Radio link for reliable communication, the process is know as Radio Link Monitoring (RLM). The […]
What are the most common Test Cases for 5G Device Verification?
As per 3GPP specifications, the 5G is design and developed to support three major use cases i.e. eMBB (Enhanced Mobile Broadband), URLLC (Ultra Reliable Low Latency Communication) and mMTC (Massive […]
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 […]
SSC Modes – Session and Service Continuity in 5G
In any telecom technology one of the key feature requirement is data session and service continuity to enusre the uninterrputed service experience to the users irrespective of any change of […]
5G NR SDAP – Service Data Adaptation Protocol
The 5G NR has introduce new mechanism to manage the Quality of Service via QoS flow and to handle QoS flow specifications has introduced a new Sublayer SDAP in air-interface […]
5G NAS Mobility Management – 5GMM
At 5GC, NAS Mobility Management (5GMM) procedures are responsible to keep track whereabouts of the UE, UE authentication and control integrity protection and ciphering. The 5GMM procedures also used by […]
5G NAS – Authentication Failures Cause Values
In 5G Network, Non-access stratum (NAS) layer managed the PLMN specfic Network Failure and Authentication Failures between the 5G UE and 5G Core. Mutual authentication is a mandatory security procedure […]
5G NAS – Registration Reject Cause
In 5G NR, Registration is a NAS layer or 5G Mobility Management (5GMM) process and it is very much similar to the Attach Process in LTE except some of the […]
