Dynamic Soft Buffer Allocation for Wireless Device Memory

The patent implements dynamic soft buffer allocation where the soft buffer size is adjusted based on the actual number of unsuccessfully decoded code blocks. Instead of fixed allocation per HARQ process, the buffer dynamically adapts its size to match the actual storage needs, eliminating wasted memory while maintaining simplified management through automated adjustment mechanisms.

The patent reduces UE costs by implementing dynamic soft buffer allocation that adjusts buffer size based on actual storage requirements. The buffer expands only when needed to store unsuccessfully decoded code blocks and contracts when not needed, significantly reducing the overall memory capacity required in the UE while maintaining automated management.

The patent enables effective incremental redundancy for large transport blocks through dynamic buffer allocation that automatically expands to accommodate additional redundancy information. The buffer size is adjusted based on the number of unsuccessfully decoded code blocks, allowing the system to maintain ease of operation while significantly improving adaptability for handling large transport blocks with multiple retransmissions.
