Solution Overview
Problem
Wireless communication systems face challenges in effectively mitigating errors in voice communications due to bit errors, which affect the quality and reliability of voice data transmission.

The method involves obtaining erroneous voice packets, determining bit error rate (BER) information, and generating partially decoded voice packets to facilitate error mitigation by decoding at least a portion of the voice packets based on the BER information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voice packets are transmitted over wireless communication channels, then communication coverage and connectivity are improved, but bit errors occur during transmission which degrade voice quality and reliability
Solution Approach 1:
The patent applies preliminary action by performing partial decoding of voice packets before they are fully processed. The base station decodes a portion of each voice packet and transmits the partially decoded packets along with BER information to the UE. This advance processing allows the UE to mitigate errors more effectively when reconstructing voice data, as it has head-start information about the encoding structure and potential error locations.
Solution Approach 2:
The patent implements feedback by transmitting BER (Bit Error Rate) information from the base station to the UE based on the partially decoded packets. This feedback mechanism provides the UE with quantitative information about the quality of received packets, enabling dynamic error mitigation strategies. The UE uses this BER feedback to adjust its error correction and voice data reconstruction processes, improving overall reliability.
2Reliability
If error mitigation techniques are applied at the UE, then voice quality is improved, but additional processing complexity and computational requirements are introduced
Solution Approach 1:
The patent applies segmentation by dividing the voice packet processing into multiple stages. Instead of attempting to fully decode and process entire voice packets at once (which would be computationally intensive), the base station performs partial decoding and segments the processing tasks. The UE then receives these segmented partially decoded packets and performs lighter error mitigation processing on each segment, reducing overall computational complexity while maintaining voice quality.
Solution Approach 2:
The patent implements partial action by performing only sufficient decoding operations rather than complete decoding of all voice packets. The base station decodes a portion of each packet to generate partially decoded packets, which contains enough information for the UE to perform error mitigation without requiring full decoding. This partial action approach reduces processing complexity at both the base station and UE while still achieving the goal of improving voice data quality.
3Reliability
If partial decoding is performed on voice packets, then error mitigation capability is enhanced, but transmission time and processing delay increase
Solution Approach 1:
The patent applies partial action by performing only the necessary portion of decoding operations. The base station performs partial decoding of voice packets - enough to extract BER information and create partially decoded packets for error mitigation, but not complete decoding of all packets. This selective partial processing enhances error mitigation capability while minimizing the additional time required compared to full decoding, thus reducing processing delay.
Solution Approach 2:
The patent implements preliminary action by performing partial decoding in advance at the base station before transmission to the UE. This preliminary processing prepares the voice packets with embedded error mitigation information, so that when the UE receives them, the error correction can be performed more quickly with less computational burden. The advance preparation reduces the real-time processing delay at the UE while maintaining enhanced error mitigation capability.
