Unified Precoding for Multiple Transport Blocks in LTE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LTE system faces inefficiencies when transmitting multiple transport blocks due to the use of different precoding for each block, leading to reduced system performance and inability to meet requirements for high-order modulation and large data transmission.
Innovation Solution
The method involves using the same precoding matrix for multiple transport blocks, cross-mapping them onto time-frequency resources, and configuring different modulation and coding schemes (MCS) based on channel conditions, allowing for flexible scheduling and improved system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different precoding is used for each transport block, then each block can be optimized independently, but system performance decreases and coding/modulation efficiency is reduced
Solution Approach 1:
The patent merges the precoding operation for multiple transport blocks into a single unified process. Instead of applying separate precoding matrices to each transport block independently, the invention combines all transport blocks and applies a single precoding operation, thereby improving coding and modulation efficiency while maintaining or enhancing system performance through coordinated transmission.
2Adaptability or versatility
If multiple transport blocks are transmitted with individual precoding, then flexibility in transmission is maintained, but system performance and ability to support high-order modulation is reduced
Solution Approach 1:
The patent combines multiple transport blocks into a unified transmission stream with a single precoding operation, enabling more efficient use of available resources and supporting higher-order modulation schemes. This merging approach improves system performance by optimizing the overall transmission rather than treating each block separately, while still maintaining flexibility through the ability to dynamically adjust the combined transmission parameters.
