This case moves UWB schedule parameters into narrowband advertisements, reducing request-response exchanges for ranging setup.

UEs report connected-state positioning support so networks can configure measurement gaps without idle-state transitions.

A Bluetooth sink retrieves source-device data, selects a target, and triggers reconnection without manual re-pairing.

Assistance data lets receiver sensing nodes assign reflected-signal measurements to multiple targets, improving distinction and tracking accuracy.

Terminal signal-strength checks let the server gate voice-call requests, avoiding useless traffic when fringe-network reception cannot support a call.

Contention-based access makes NR paging unpredictable; multiple monitoring occasions improve delivery chances while selective UE checks limit power use.

Sending small data packets with the RRC resume request lets an inactive UE advance transmission, reduce delay, and return to inactive state faster.

NAS policies and network assistance streamline D2D service discovery and call establishment while preserving control over direct WTRU-to-WTRU paths.

Multiplexed random-access and data signals carry control information together, reducing transmission delay and repeated carrier sensing for URLLC.

This case uses assistant information to choose base-station transmission or anchor relocation, reducing signaling overhead and delay for small data.

Per-stream policing and filtering use DS-TT and NW-TT translators to connect 5G with TSN while managing reliable, low-latency traffic.

See how an MT UE detects SIP failure scope and switches across LTE, Wi-Fi, 3G, or 2G to preserve incoming voice service.

By grouping UEs with similar RSRP values across RIS cells, the base station shares frequency bands while limiting collisions and interference.

Secure the SEPP–IPX connection with a TLS or IPsec VPN tunnel, HTTP proxying, and protected 5G HTTP messages.

Using UE location and consecutive failure counts, an ML model predicts beam failure risk to trigger earlier 5G recovery and reduce latency.

After IMS PDN release, the UE uses a shared secondary IP over the internet PDN to receive call alerts and reconnect.

Relay UEs align IPv4, IPv6, or Ethernet data types with matching PDU sessions to prevent transmission failures.

Configured LBT windows let sidelink UEs contend for shared-band channel occupancy, reducing repeated DCI grants, HARQ reporting, and latency.

Failure-cause feedback lets terminals adjust resource levels and retry actions for insufficient capacity, capability mismatch, or authentication failure.

See how one DCI grant schedules multiple sidelink TBs, reducing repeated signaling and latency while preserving flexible UE communication.

Dual 6 GHz radios assign separate channel ranges and enable transition-band filtering to limit interference during ultra-low-latency connections.

Configurable delays let user plane nodes verify path recovery before reporting failure, reducing signaling and preserving bearer contexts during transient outages.

Terminal load indicators guide QoE measurement decisions, helping prevent overload while preserving efficient report transmission and storage.

When an AMF cannot contact NG-RAN nodes, it reports the failures to the MB-SMF for multicast or broadcast session remediation.

PCI-linked TCI states help terminals distinguish DL and UL configurations across multiple TRPs, improving communication quality.

RRC, MAC CE, and DCI signaling coordinates multiple TCI states to improve beam management and reliability across multi-TRP links.
