5G NR RRC Timers, Counters and Constants
5G NR radio resource control (RRC) has introduced following listed timers, counters and constant for reliable functioning of procedures like RRCsetuprequest, RRCreestablishment, RRCresume, RRCsuspend etc. RRC timer indicates the timer […]
5G NR RRM Measurement Requirements
In 5G NR, the Sync Signal/PBCH block (SSB) burst is consists of multiple SSBs. These multiple SSBs are associated with the different SSB indexes and with the different transmission beams […]
What is Sub-6 GHz & mmWave in 5G and Why mmWave bands are required?
As we all know, we have cell phone towers or antennas placed all around us which provide our phones with the coverage they need to keep us connected to the […]
5G NR Physical Cell ID (PCI) Planning
Each 5G NR cell corresponds to a Physical Cell ID (PCI) and it is used to distinguish cells on the radio side. The PCI planning for 5G NR is very […]
5G Identifiers SUPI and SUCI
In telecommunication systems, network operator allocate to each SIM card a unique identifier, known up to the 4G as an IMSI (International Mobile Subscriber Identity) and for the 5G as […]
Open RAN (O-RAN) Reference Architecture
The O-RAN Reference Architecture is designed to enable next generation RAN infrastructures. It is designed with the principles of intelligence and openness, the O-RAN architecture is the foundation for building […]
5G System Connection Management: CM-Idle and CM-Connected
When a Mobile wants to communicate with 5G core network, as it first time switched-on or because it was in idle state for some time and network removed the resources […]
5G Network Sharing: Concept, Benefits and Architectures
The deployment of a new telecommunication network and its operation can lead to very high costs and a long entry time to business for a operator. Sharing the network infrastructures […]
