Learn about 5G DMRS for PBCH (1) What is the primary function of DMRS for PBCH? * The UE uses DMRS to estimate the propagation channel experience by the PBCH. The resultant information is used to demodulate the PBCH and subsequently decode the Master Information Block. (2) How and where is
What are 4G S-TMSI and 5G S-TMSI? * 4Gย ย S-TMSI, and is part of GUTI, it is used to identify a UE within a specific MME Pool. * 5Gย S-TMSI can be used to identify a UE within a specific AMF Region. How can you trace and check them? * In 4G: It
๐ก What is it? PDSCH Multiplexing simply means leveraging the free resources within the PDSCH DMRS Symbol for optimal PDSCH utilization. ๐Expected Gain: Experience an increase in the maximum user throughput for users in good radio conditions. ๐ซ Expected Drawbacks: There's always a tradeoff. Be mindful of the impact on
5G NSA Training Session 8 about DL Transmit Power Design in 5G, is now on YouTube. In this video, weโll cover key concepts, including: * What are EIRP and EPRE? * How to calculate Cell Reference Power in 5G. * How to analyze power configurations using UE logs. * The impact of SSB
The Channel State information (CSI) Reference Signal is a multi-purpose DL Transmission. The Base Station can configure the UE to use the CSI-RS for one or more of the following: 1- CSI Reporting As seen in the below figure, the g-NB initially will send the related configuration and transmit CSI
Even though I donโt often use Excel for KPIs monitoring or reporting, the need for quick KPIs checks and reports still arises. In such cases, Excel is still needed, especially when some automation can speed up the process and improve efficiency. In this video, I'll show you
* The 4G/5G Globally Unique Temporary Identifier (GUTI) is a temporary identity used by the network to enhance privacy. The MME assigns it in 4G or AMF in 5G, and the allocated GUTI can be changed at any time by MME/AMF. * 4G GUTI has three components. Where: * PLMN identity
5G CSI-RS has 3 Types: 1- Non-Zero Power CS RS is used for two main purposes ย - For Channel Measurement CSI reporting, Beam Management, RLF, Beam Recovery, and Mobility. ย - For Interference Measurement, โIntra-Cell Interferenceโ is mainly used to measure intra-Cell interference generated by Users during Multi-User MIMO 2- CSI
