5G Carrier Aggregation – Bandwidth Classes
Carrier Aggregation (CA) increases the bandwidth by combining several carriers. Each aggregated carrier is referred to as a Component Carrier (CC). 5G NR CA supports up to 16 contiguous and […]
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 NR Cell Global Identity (NCGI) Planning and Calculations
In 5G, NR Cell Global Identifier (NCGI) is used to identify NR cells globally and similar to ECGI (EUTRA Cell Global Identifier ) in 4G LTE. The NCGI is constructed […]
O-RAN – Fronthaul Delay and Its Management
O-RAN Split Option 7-2x, introduced a functional split between O-DU and O-RU within the PHY Layer of the radio interface. This split cause some delay in transmission and reception of […]
O-RAN Fronthaul Transport Synchronization Configurations
O-RAN maintains network timing distribution as the preferred approach within the fronthaul network. Time and frequency synchronization needs to be distributed to O-DU and O-RU for the effective O-RAN network […]
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, […]
3GPP Evolution for MIMO
Released 3GPP standards on MIMO are shown in below image. As you know, Coordinated Multipoint (CoMP) is a type of Cooperative MIMO, in which data and channel state information (CSI) are […]
5G NSA Option 3.x Deployment Interface BW Calculation
5G NSA 3.x Architecture 5G NR, initial deployments are based on 5G NSA, also known as Option-3. There are multiple variants of Option-3 namely option 3, Option 3a and Option […]
5G NR RACH Procedure Overview – CBRA & CFRA
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, In […]
