HARQ Communication Module With Phase-Difference Packet Combining

The patent segments the error correction process into multiple parallel paths: one path handles initial packet correction using traditional HARQ methods, while another path processes retransmitted packets through enhanced combining operations. This segmentation allows the system to improve packet reception success rate by handling different packet scenarios through specialized sub-systems, rather than requiring a complete redesign of the entire error correction mechanism.

The patent introduces a new dimension to error correction by implementing multi-path processing for retransmitted packets. Instead of simply repeating the same correction process, the system adds a combining operation dimension that integrates information from multiple received packets across different time instances. This dimensional expansion enables more robust error correction without fundamentally complicating the base HARQ structure.

The patent applies preliminary action by pre-configuring multiple error correction paths and combining operations before retransmitted packets arrive. The system prepares the processing framework in advance, so when retransmitted packets are received, they can be immediately routed to appropriate correction paths without requiring sequential decision-making. This preliminary preparation reduces the actual processing time while maintaining multiple correction operations.

The patent ensures continuity of useful action by implementing parallel error correction paths that operate simultaneously rather than sequentially. Multiple correction operations are performed concurrently on different packet segments or through different algorithms, maintaining continuous processing flow. This approach allows the system to perform thorough error correction without the time penalty of sequential processing, as the useful computational actions continue uninterrupted across multiple paths.

The patent applies local quality by implementing enhanced combining operations selectively rather than uniformly across all packets. The system identifies specific packets or packet segments that benefit most from enhanced combining based on their error characteristics, and applies the computationally intensive operations only to those cases. This localized application of enhanced processing improves error detection accuracy where needed while avoiding unnecessary computational complexity for packets that require standard processing.

The patent employs partial action by implementing a tiered combining strategy where basic combining operations are performed on all packets, and enhanced combining operations are applied partially to retransmitted packets based on their specific needs. The system performs exactly the right amount of combining - not too little to miss errors, not too much to waste computation. This partial application of enhanced operations optimizes the balance between error detection accuracy and computational complexity.
