Transmission Link Error Control System TRIZ Cases

Maps configured grant PUSCH repetitions across multiple TRPs with per-TRP RV and hopping to improve FR2 uplink reliability under blocking.

Predetermined transport block retransmissions maintain sidelink reliability when feedback is disabled, avoiding unclear ACK-based recovery.

RNTI-specific fallback HARQ indications replace semi-static multicast codebooks to keep UE behavior consistent and feedback interpretation accurate.

Dedicated HARQ-to-MBS mapping and selective non-HARQ reception reduce multicast data loss when limited HARQ processes must support multiple services.

Block acknowledgment feedback identifies overlapping dropped frames across links, enabling adaptive MPDU aggregation with fewer retransmissions.

PDCP status in the switch command helps relay-path handover cut packet loss and maintain service continuity during data transmission.

Adaptive blind retransmission uses distance and retry count to sustain out-of-range V2X delivery while limiting signaling overhead.

Multi-time feedback from relay and remote UEs guides HARQ retransmission, extending sidelink groupcast range with lower latency.

When LBT blocks lower-priority PSFCH feedback, this case shows sidelink resource switching that preserves higher-priority reception efficiency.

Configured resource subsets guide UE monitoring for sidelink control information, cutting blind decoding time and power in retransmissions.

Packet loss feedback sets a safe drop limit for obsolete wireless packets, reducing latency and resource use without harming reconstruction.

Priority and frequency-domain PSFCH mapping with a configured gap period reduces dropped sidelink feedback and lowers latency.

Priority-based HARQ feedback selection in sidelink links cuts unnecessary retransmissions and eases congestion while preserving critical ACK/NACK delivery.

ACK-based sidelink HARQ stops configured-grant retransmissions early, improving V2X reliability while freeing radio resources.
