VoLTE RAN Features(Exist DRX based on SINR, Access Network bitrate change and UL FSS) - Session 6

This video covers Session 6 of the E2E VoLTE Training Campaign. In this session, we will explain the below features functionalities and how to verify these features from logs and field testing:

  • VoLTE Main Features Introduction
  • Exist DRX based on UL SINR
  • VoLTE Codec Rate Change(ANBR)
  • UL Frequency Selective(FSS)

Introduction * HARQ is one of the most important reliability mechanisms in the 5G MAC layer. It directly affects retransmission speed, uplink control overhead, latency, and overall scheduling efficiency. * In simple words, HARQ gives 5G a fast retransmission loop. It helps recover transmission errors much faster than higher-layer recovery, which is
