Homogeneous Cell Lifecycle Mgmt - Cell State Mgmt (IS/OOS)

Feature Supported
Ability to support cell activation and de-activation. This is commonly refered to as taking a carrier OOS (Out of Service) and bringing it to IS (In Service) states Y

Aerial SDK Overall Beam and Carrier Mobility

Feature Configuration Supported
Inter-gNB Handover UE moves from 1 gNB to another gNB
  • UL RRC transfer
  • UE Context Modification Request/Response
  • UE Context Release
  • Serving and Target gNB cells can support different frequencies
Intra-DU Handover Cell-level Mobility - UE establishes new connection to new carrier (inter-cell) supported by UE context modification procedure
  • UE Context Modification Request/Response
  • UE Context Release
  • Serving and Target Cells can support different frequencies
Beam Mobility UE establishes data path to new beam within carrier coverage (intra-cell) No
Mobility at low speeds Aerial SDK shall support pedestrian mobility by modeling the 3GPP channels and 38.104 requirements N
