Aerial SDK features for 5G gNB
A 5G gNB capabilities, procedures, interfaces has dependencies on Aerial SDK PHY Layer. The purpose of this section is to ensure Aerial SDK provides support for gNB capabilities, procedures and interfaces.
Dynamic M-plane (dest MAC and VLAN ID) support
PUCCH Format 1 I+N and SINR, DTX for UCI on PUSCH
Predefined BeamId support
Foxconn O-RU support
Cell life cycle management with static cell config
Multi-cell support for upto 4 simultaneous homogeneous cells (statically configured)
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
|
N |
| Intra-DU Handover | Cell-level Mobility - UE establishes new connection to new carrier (inter-cell) supported by UE context modification procedure
|
N |
| 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 |
