4G VoLTE Call Procedures: Attach, IMS, and Capability Checks
In this video, we explain VoLTE call procedures in 4G LTE. You will see how attach and registration work, how IMS APN and QCI5 activation are done, and how UE and EPC capabilities can be checked from logs. A clear step-by-step view of VoLTE call setup and signaling. #VoLTE #4G
5G PDCCH Beamforming Explained: Common vs User Beamforming
Unlike 4G, 5G supports PDCCH beamforming. In this video, we’ll give a high-level overview of 5G PDCCH common and user beamforming, including its use cases.
UE SRS Antenna Switching in 5G — How It Works?
In this video, we explain how 5G uses SRS antenna switching to estimate the downlink channel in TDD mode, why the UE switches antennas, and how to check if a UE supports this feature for accurate beamforming. #5G #SRS ##3GPP
How gNB Uses SRS for 5G PDSCH Beamforming- Quick and Clear
In this video, we explain how 5G uses SRS — the Sounding Reference Signal — to perform PDSCH beamforming in TDD networks. Using the concept of channel reciprocity, the gNB can estimate the downlink channel based on uplink SRS measurements. We’ll walk through how the process works, when it's
