Since the role of RIC is to enable near realtime control loop actions, latency is an important set of telemetry to be collected and reported - E2 latency and RIC processing latency. E2 latency includes telemetry that measures incoming messages/data to the RIC as well as outgoing messages from the RIC to Managed Functions. RIC processing latency is telemetry that measures the RIC/xAPPs control loop processing time to receive messages, apply analytics, determine control loop actions and generate outgoing messages to RAN Managed Function over E2. As the RIC matures release over release, latency telemetry must be defined and implemented.
Near-RT RIC angle: RIC-30, RIC-33, RIC-35, RIC-69 for latency measurements
Note: It may be appropriate to group xAPP health checks for a subset of xAPPs that have dependencies on each other. But for the initial implementation, each xAPP is treated independently.
