Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of multiple component carriers in flexible spectrum integration schemes for wireless communication networks is challenging due to differing bit encodings, making seamless integration of bits across carriers difficult.
Innovation Solution
A method involving separating transport blocks into multiple layer sets across subbands and interleaving or jointly interleaving bits within and across these sets for efficient mapping and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple component carriers are integrated into a single virtual carrier, then spectrum utilization flexibility is improved, but bit encoding differences between carriers make integration complex
Solution Approach 1:
The patent segments the transport block into multiple code blocks, which are then distributed across different layer sets in different subbands. This segmentation allows each code block to be independently mapped to appropriate layers based on their encoding characteristics, resolving the complexity of integrating bits from multiple carriers with different encodings into a unified virtual carrier structure.
Solution Approach 2:
The patent introduces layer sets as intermediary structures that mediate between the transport block and the individual component carriers. Each layer set acts as a buffer that can accommodate bits from different carriers with different encodings, facilitating their integration into the virtual carrier while maintaining the original encoding characteristics.
2Productivity
If bits from multiple component carriers are mapped to the same virtual carrier, then communication efficiency is improved, but different modulation orders in different subbands complicate the mapping process
Solution Approach 1:
The patent segments the mapping process into separate operations for different layer sets. Each layer set is processed independently to handle the specific modulation order required for that subband, then the results are combined. This segmentation simplifies the overall mapping process by breaking down the complex task of handling multiple modulation orders into manageable independent operations.
Solution Approach 2:
The patent applies local quality by assigning different modulation orders to different layer sets based on the specific requirements of each subband. This allows each layer set to be optimized for its local conditions while contributing to the overall communication efficiency of the virtual carrier, resolving the complexity of uniform mapping across heterogeneous subbands.
