Channel Coding Adaptation TRIZ Cases

Routing NC PDUs by path and domain improves radio resource use while preserving network coding gains in wireless transmission.

By inserting or deleting rate adaptation code blocks only at safe code block boundaries, this case preserves packet parsing correctness in MTN Ethernet PCS.

Separate feedback resources for common and private rate-split messages improve decoding reliability and reduce transmission conflicts.

Spaced subcarrier mapping separates video and haptic data within one RB to cut frequency-domain interference and improve transmission reliability.

Segmented transport block repetitions add timed gaps so IoT devices can save power between bursts while maintaining reliable coverage.

Different code rates within one RRC message keep control data reliable while speeding AI model transfer with selective segment retransmission.

NACK-only HARQ feedback for downlink SPS lets the UE signal PDSCH decoding failure without full ACK overhead, improving feedback efficiency.

Adaptive network coding selects encoding and link weights by application type and network status to cut latency and improve reliability.

Per-layer transport blocks let pre-equalized MIMO waveforms use adaptive coding per layer, reducing ppSNR imbalance, retransmissions, and receiver power.

A fixed PTRS pattern and density for PDSCH or PUSCH retransmissions avoids missed DCI mismatches and reduces UE decision burden.

Cross-block check blocks target least reliable polar-coded bits, cutting feedback overhead and decoding complexity in retransmissions.

Alternating different waveforms across PUSCH repetitions improves uplink resource use and raises transmission success under configured wireless links.

Adaptive transport block sizing based on channel quality and delay cuts HARQ retransmission overhead in long-delay wireless links.

Receiver feedback separates actively discarded packets from congestion loss, enabling adaptive AL-FEC ratios for more efficient 5G media delivery.

Adjusts rate-matched bit start positions by RV across FD and HD uplink slots to avoid data loss and unnecessary PUSCH repetition.

Gradient-norm-based modulation and coding selection cuts wireless federated learning delays and bit errors during model updates.

Flexible MCS tables add 4096-QAM for terminals with strong channel quality, improving NR link adaptation and spectral efficiency.

Effective SINR from RBIR and channel orthogonality helps AMC choose MCS with near-MLD accuracy and lower MIMO-OFDM complexity.

Dynamic slot-based codebook switching lets a UE match feedback size and reliability to slot conditions, cutting uplink overhead.

Phase rotation and amplitude scaling encrypt complex modulation symbols to strengthen 5G and 6G communication security with manageable complexity.

UE control information lets networks stitch coded packet portions across time-frequency resources, cutting processing burden without losing coding gain.

Adaptive offset compensation adjusts MCS to channel state, avoiding unnecessary throughput loss at low SINR and underuse at high SINR.
