In Release 15 of the 3rd Generation Partnership Project (3GPP) 5G new radio (NR), the basic handover is mainly based on the long-term evolution (LTE) handover mechanism in which a network controls mobility of user equipment (UE) based on measurement reports from UE. In the basic handover, a source next generation Node B (gNB) triggers a handover by sending a handover request to a target gNB. After receiving acknowledgement from the target gNB, the source gNB initiates handover by sending to a UE a handover command containing target cell configurations. The UE synchronizes to the target cell after the radio resource control (RRC) reconfigurations are applied with the target cell configurations.

What’s inside:

  • Basic handover procedure vs DAPS-based handover procedure
  • Channel state change during handover procedure and handover failure
  • Conditional handover procedure
