5G CSI-RS has 3 Types:

1- Non-Zero Power CS RS is used for two main purposes
- For Channel Measurement CSI reporting, Beam Management, RLF, Beam Recovery, and Mobility.
- For Interference Measurement, “Intra-Cell Interference” is mainly used to measure intra-Cell interference generated by Users during Multi-User MIMO

2- CSI Interference Measurement Resources
- Mainly used for Interference Measurement, “Inter-Cell Interference” measures the interference reported or detected from Neighbor cells during SU-MIMO

3- Zero Power CSI RS
- Define a Rate matching Pattern Serving Cell that May transmit on configured REs

Learn about 5G DMRS for PBCH

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

Overview about 4G S-TMSI and 5G S-TMSI

What are 4G S-TMSI and 5G S-TMSI? * 4G S-TMSI, and is part of GUTI, it is used to identify a UE within a specific MME Pool. * 5G S-TMSI can be used to identify a UE within a specific AMF Region. How can you trace and check them? * In 4G: It
