Life Cycle Management (LCM) : LCM is a set of functions required to manage the instantiation, maintenance and termination of a Virtual Network Function (VNF) or Network Service (NS). Network […]
NFV Management and Orchestration [MANO] Key Performance Indicators [KPIs]
NFV management and orchestration (MANO) systems are being developed to meet the agile and flexible management requirements of virtualized network services in 5G Networks. Regarding this, ETSI ISG NFV has […]
5G NR Interfaces X2/Xn, S1/NG, F1 and E1 Functions
In LTE networks, X2 and S1 interface are defined as an interfaces between RAN nodes and between RAN and Core Network. 5G is expect to operate in two modes as […]
Robust Header Compression – ROHC
ROHC is a header compression protocol/algorithm that can be used compress the header of different IP packets. In normal case without compression IPv4 header is 40 bytes and IPv6 header […]
TTI Bundling for better HARQ and Latency
TTI bundling enables a data block to be transmitted in consecutive TTIs, which are packed together and treated as the same resource during the scheduling process. TTI bundling makes use […]
How to get better ACLR in TX chain ?
If you are trying to debug the bad ACLR in TX Chain or you are designing a TX for your system, then you must take care following points with regards […]
LTE Cell Camping and Selection Procedure
Cell Selection and Re-selection: After selecting a PLMN, a UE selects a cell in the PLMN to camp on. After camping on the cell, the UE monitors system information, performs […]
5G NR gNB Higher Layer Split (HLS)
The NG-RAN architecture with a split gNB function is shown in Figure below. Here in NG-RAN a set of gNBs is connected to the 5G Core Network (5GC) through the […]
PLMN Selection in LTE (Idle Mode Action)
UEs can be either in RRC_CONNECTED or RRC_IDLE mode. UEs will be declared as RRC_IDLE if there is no RRC connection between the UEs and the eNodeB and RRC_Connected when […]
