Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently communicating transport blocks across multiple component carriers, leading to increased overhead and reduced spectrum efficiency due to separate configuration and resource allocation for each carrier.
Innovation Solution
Mapping a transport block across multiple component carriers associated with at least one slot of time-frequency resources, allowing for unified transmission and reception, thereby reducing the need for separate configuration and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate configuration and resource allocation is used for each component carrier, then each carrier can be independently managed, but overhead increases and spectrum efficiency decreases
Solution Approach 1:
The patent combines multiple component carriers into a single carrier for transmission purposes. The source device merges data from multiple CCs and transmits them as one combined carrier, while the destination device receives and separates them. This merging approach reduces configuration overhead and improves spectrum efficiency while maintaining the ability to manage multiple carriers independently through the combination-separation mechanism.
2Adaptability or versatility
If separate configuration and resource allocation is used for each component carrier, then each carrier can be independently managed, but spectrum efficiency is reduced
Solution Approach 1:
By merging multiple component carriers into a single transmitted carrier, the system improves spectrum efficiency. The combining process allows for more efficient use of spectral resources through consolidated transmission, reducing waste and improving overall spectrum utilization while still supporting independent carrier management at the configuration level.
3Productivity
If transport blocks are transmitted across multiple component carriers, then bandwidth utilization improves, but processing complexity increases
Solution Approach 1:
The patent segments the transport block into multiple code block groups, which are then distributed across different component carriers. This segmentation approach allows parallel processing at the receiver, where each code block group can be processed independently on its respective carrier, thereby managing processing complexity through division of labor while achieving improved bandwidth utilization through parallel transmission paths.
Solution Approach 2:
The source device merges multiple data streams from different component carriers into a single transport block before transmission. At the destination, the reverse operation separates the received carrier back into individual code block groups for processing. This merging-separation approach simplifies the transmission process while enabling efficient parallel processing at the receiver端.
4Productivity
If transport blocks are transmitted across multiple component carriers, then bandwidth utilization improves, but power consumption increases
Solution Approach 1:
By segmenting the transport block into code block groups that can be processed independently on each component carrier, the system enables parallel processing that improves bandwidth utilization. The segmentation allows the receiver to process multiple carriers simultaneously, achieving better throughput while distributing power consumption across multiple processing units rather than concentrating it in a single high-power processor.
