Parity Check Coding for Bursty Interference Retransmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bursty interference in wireless communication networks leads to inefficient retransmissions of entire data blocks due to partial information loss, consuming excess resources and degrading network performance.
Innovation Solution
A method involving the generation and transmission of code blocks and parity check code blocks by base stations to mobile devices, where parity check code blocks are used to correct errors in received code blocks, allowing for selective retransmission of affected blocks rather than entire transmission blocks.

Engineering Contradiction Analysis
1Reliability
If entire transmission blocks are retransmitted due to partial information loss from bursty interference, then data integrity is maintained, but network resources are wasted and efficiency deteriorates
Solution Approach 1:
The patent divides a transmission block into multiple code blocks, each independently encodable and decodable. When bursty interference affects only certain code blocks, the receiver can identify and request retransmission of only those specific code blocks rather than the entire transmission block. This segmentation enables selective retransmission, maintaining data integrity while reducing unnecessary retransmissions of unaffected data, thereby improving network efficiency.
2Productivity
If selective retransmission of affected blocks is implemented, then resource consumption is reduced, but system complexity increases due to need for block-level error detection and management
Solution Approach 1:
The patent incorporates error detection mechanisms (such as CRC checks) and identification information into each code block during the initial encoding phase. This preliminary action enables the receiver to quickly identify which code blocks are corrupted without requiring complex post-reception analysis. The pre-configured error detection and identification structures simplify the overall error management process while enabling efficient selective retransmission.

AI summary
Coding for bursty interference is discussed in which a base station receives data bits for transmission. The base station may generate code blocks including information bits and parity bits. The base station may also generate parity check code blocks including information bits corresponding to information bits of the generated code blocks. The base station may transmit the code blocks and the parity check code blocks to a mobile device to improve decoding. When errors are detected, the mobile device may decode the received code blocks using hard or soft parity checks and the parity check code blocks.
