Running xApps
Real-time status of deployed O-RAN xApps on GKE · Last updated: 3:05:31 PM
GPU-accelerated UE emulation with 3GPP CDL-C channel, ray tracing, 50 UEs per pod, ISAC sensing
GPU ray tracing for urban micro cell, 5 reflections, scattering, ISAC target detection
Network forecasting, anomaly detection, ISAC classification, digital twin predictions
Automated network optimization - beam, power, scheduling, energy efficiency
5G CU with NGAP/F1AP/E1AP interfaces, connected to 3 DUs, 4 network slices (eMBB, URLLC, mMTC, ISAC)
5G DU with MAC/RLC/PDCP layers, n78 band (100 MHz), 30 kHz SCS, connected to 4 RUs each
O-RAN 7.2x Split RU with eCPRI fronthaul, FR1 (n78, 64T64R) + FR2 (n257, 256-element phased array), ISAC enabled
Access and Mobility Management Function, handles UE registration, authentication, and mobility
Session Management Function, manages PDU sessions and QoS flows
User Plane Function, handles data forwarding with 10+ Gbps throughput capacity
Manages E2 interface connections between Near-RT RIC and E2 Nodes (gNBs). Handles E2 Setup, configuration update, and node health monitoring.
Manages E2AP subscriptions from xApps. Handles subscription lifecycle, conflict detection, and routing table updates.
RAN Network Information Base (R-NIB) persistent store. Provides SDL (Shared Data Layer) for all RIC platform components.
Maintains RMR routing tables. Distributes message routes to all platform components and xApps.
SCTP endpoint for E2 interface — terminates E2AP messages from gNBs and forwards to E2 Manager.
Range estimation (±0.3m), velocity detection, AoA, presence detection
ITU-R P.838 rain rate estimation (±2mm/hr), humidity sensing
NVIDIA AODT 1.4.0 synchronization, network state mirroring
NTN failover (<30s), survivor detection, emergency mesh networking
Real-time per-UE and per-cell KPI streaming to Near-RT RIC xApps via E2 subscriptions.
Closed-loop RAN control actions — xApp sends RC Insert/Control messages to steer DU/CU behaviour.
Cell-level configuration and energy-saving controls; aligned with O-RAN WG3 CCC v3.x specification.
ISAC service model — exports sensing primitives from 5G PHY layer to Near-RT RIC for AI processing.
