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 […]

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 […]

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 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 […]
