Overview about 5G CSI-RS Types

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

LTE Attach Procedure | E2E Call Flow, MME, EPS Bearer & Default Bearer | 4G E2E Signaling Session 5

Session 5 of my 4G/LTE E2E Signaling series is out: the LTE Attach Procedure. Attach is the first thing a phone does on an LTE network. It registers, gets authenticated, receives an IP address and sets up the Default EPS Bearer. In this session: → Attach Functions & Triggering Conditions

RACH CBRA/CFRA Call Flow and Use Cases

Overview The Random Access procedure can be initiated in different situations depending on whether the network already knows the UE and whether dedicated resources can be assigned. Random Access Channel, or RACH, is used whenever the UE needs to establish or recover uplink synchronization with the network. In 5G, Random
