General principles of beam management in mmwave


General principles of beam management are in mmwave are as follow :

P1: Beam Establishment (initial gNB beam acquisition)

Beam sweeping is used to cover a given area (e.g. 120° span)

  • On gNB side wide beam sweeping is used, UE detects best beam
  • In this procedure wide beams are used both on gNB and UE sides

 P2: gNB beam refinement & tracking (gNB Tx)

  • gNB refines beam (e.g, sweeping narrower beams within a wide beam)
  •  UE switch from wide to narrow beam or change of narrow beam

 P3: UE beam refinement & tracking (UE Rx)

  • gNB fixes a beam, UE measures currently used gNB beam and selects a narrower receiver beam
  • Wide beam can be used as initial access and fall-back in case of loss of narrow beam
