Open RAN Integration – Where We Today

Open RAN is being deployed by multiple Service Providers around the world. These deployment are large scale deployments in some of the largest countries in the world. In Open RAN […]

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 – 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 RA-RNTI Calculation

A 5G UE picks a random preamble for RACH procedure to get the uplink synchronisation. The preamble is referenced with an ID know as  RAPID (Random Access Preamble ID). 5G […]

5G NR System Information Type#3 – SIB 3

In 5G NR, SIB3 contains neighboring cell related information relevant for intra-frequency cell re-selections only. It includes cells with specific re-selection parameters and blacklisted cells information. Characteristics of NR System […]

5G NR System Information Type#2 – SIB 2

In 5G NR, System Information Block Type 2 or SIB2  provides information which is common to intra frequency , inter frequency and inter-system cell (NR – LTE) reselection. It also […]

5G NR Measurement Gap Configuration

A Mobile device has to measure the neighboring cells signal and other carrier components. Having a single RF module to control the Mobile manufacturing cost and form factor, device has […]
