5G NR Transport Block Size (TBS) Calculation

Transport Block  in 5G NR, is nothing but the payload which is passed between the MAC and Phy Layers, specifically for the shared data channel such as PDSCH and PUSCH. […]

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 […]

5G NR – Msg2 Random Access Response (RAR) – SA Mode

In 5G NR,  the initial access include down-link synchronisation and up-link synchronisation procedures. Downlink synchronisation can be achieved after decoding Minimum System Information (SSB-MIB) and Remaining System Inforatmion (RMSI- SIB […]

5G NR User Plane Latency

The definition of user plane latency as per 3GPP TR 38.913, is  “the time to successfully deliver an application layer packet/message from the radio protocol L2/L3 SDU entering point to […]

5G NR Control Plane Latency

The latency performance of a communication system is analyzed for both control plane and user plane. In this post lets discuss about control plane latency. The definition of control plane […]

5G NR BWP Types and BWP Operations

In 5G New Radio the cell bandwidth is expected to be large compared to LTE, but a UE’s receive and transmit bandwidth is not necessarily required to be same as […]

5G NR Bandwidth Part (BWP)

A Bandwidth Part (BWP) is a contiguous set of physical resource blocks (PRBs) on a given carrier. These RBs are  selected from a contiguous subset of the common resource blocks […]
