Dynamic master-slave switching lets a position indicator avoid polling conflicts, cut power use, and keep data flowing across multiple receivers.

Relay state information lets terminals screen multi-hop compatibility before access, avoiding unreliable connections and extra signaling.

Automatic onboard messaging alerts air traffic control to contingency guidance activation and upcoming maneuvers across normal and emergency frequencies.

Multiple resource types with different priorities let wireless nodes adapt QoS mapping and reduce waste from static logical channel settings.

A target UE selects an SL positioning server UE to aggregate SL-PRS measurements and deliver accurate positioning without network LMF coverage.

A relay UE assigns sidelink resource subsets to out-of-coverage UEs, cutting D2D collisions and signaling overhead.

Beam hopping parameters such as dwell time and cycle timing help terminals maintain seamless satellite coverage with limited beam resources.

Non-content X2 messages let a VRU report multiple cells to a coordinating server, improving S1-X2 handovers and X2 updates.

Coordinated COT sharing lets gNBs and WTRUs schedule sidelink transmissions in unlicensed spectrum with reduced LBT and lower interference.

Split QoS values across relay hops let intermediate UEs stay idle or inactive, improving multi-hop U2N reliability with lower RRC signaling latency.

A service-layer session manager enables secure multi-hop M2M sessions while reducing application overhead and supporting analytics and aggregation.

Identical IP addresses across PGWs let BGP choose the nearest roaming path while synchronized session data preserves redundancy and cuts delay.

Coordinated leave lets an MR-DC terminal release one connection, free transceiver resources, and support USIM operations without service interruption.

When active session counts hit a threshold, deactivating selected user plane connections cuts signaling waste and shortens service setup delay.

Paging and activation times let IoT devices wake only for 5G multicast data, improving reception reliability while cutting power use.

An RTS preempt flag and CTS-based TXOP suspension let high-priority wireless traffic access the medium with lower latency and better resource use.

Network-assisted bearer setup lets nearby WTRUs select D2D radio resources directly while preserving QoS control and interference management.

SMF shares network instance information with CU-CP, CU-UP, and UPF to align PDU session transport selection and avoid suboptimal 5G user plane mapping.

Bypassing the AMF proxy lets a radio access network connect directly to the serving control plane function, cutting signaling delay.

Primary and secondary tunnel path setup between CU and DU enables radio bearer duplication with higher reliability and manageable configuration.
