5G NR SS-RSRP Value Measurement Mapping

UE does measurement of SS-RSRP and use it for cell selection, cell reselection, power control, mobility procedures and beam management procedures. RSRP measurement generated and reported at both Layer 1 […]

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 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 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 RSRP Measurement Report Mapping

In 5G NR, RSRP measurement is performed and reported at Layer 1 (Physical Layer) and Layer 3 (RRC Layer). For example,  5G capable device can provide SS-RSRP measurements at Layer […]

Multiplex Access Technique in 5G

Multi-path propagation in a radio signal transmission causes time delays, signal distortions, and so on. Let us discuss basic theories of multiple access techniques utilized in 1G-to-5G systems for solving […]

5G NR CORESET – Control Resource Set

In 5G NR, CORESET is known as Control Resource Set. It is a set of physical resources within a specific area in Downlink Resource Grid and used to carry PDCCH […]
