Session 3 of the 5G Massive MIMO Training Series is Now on YouTube! In this session, we take a deep dive into Downlink (DL) Beam Management, a key aspect of Massive MIMO that plays a crucial role in enhancing 5G network performance. What You’ll Learn in This Video: * Introduction
5G
What is SSB? 5G Synchronization Signal Block (SSB) plays a crucial role in cell search and mobility. It consists of: * PSS (Primary Synchronization Signal) * SSS (Secondary Synchronization Signal) * PBCH (Physical Broadcast Channel) SSB occupies 20 Resource Blocks (RBs) and 4 Symbols in the frequency domain. How Does UE Detect SSB
5G
What is the SRS Transmission Comb type? * An SRS Transmission can occupy up to 272 RBs in the frequency domain, but an individual UE does not transmit the SRS on every subcarrier but selects specific subcarriers based on transmission comb type. * 5G supports two types of transmission Comb(2 &
