: These typically represent higher sensitivity levels. Choosing these can sometimes stabilize a connection in environments with high "noise" (many neighboring Wi-Fi networks) by making the adapter more conservative about when it transmits.

Cognitive radio or radar: F1 (wideband but low-resolution spectrum scan), F3 (narrower band with moderate resolution), F5 (target tracking with high resolution). EF = detection uncertainty. l2hforadaptivity ef f1 f3 f5 link

| Element | Role in Feature | |---------|----------------| | (Enhanced Feedback) | Provides real-time channel quality, load, and interference metrics from the UE and/or gNB. | | F1 link | Interface between gNB-CU and gNB-DU (in NR split architecture). Used to exchange adaptivity-related control signals. | | F3 link | Interface between gNB-DU and RU (Radio Unit). Carries IQ samples and low-level timing/phase info for rapid HO decisions. | | F5 link | Logical link for forwarding EF data from neighbor cells to the serving cell. Enables predictive handover. | | L2 Handover | Layer 2 handover (without RRC reconfiguration) for ultra-low latency mobility. | : These typically represent higher sensitivity levels
