Multi-Carrier HSDPA HARQ Module Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication technologies are limited to single-carrier High Speed Downlink Packet Access (HSDPA) support, making it difficult to manage and schedule multi-carrier resources effectively, which is inadequate for meeting the demands of multi-carrier HSDPA services.
Innovation Solution
Implementing a multi-carrier HSDPA system with network-side and user equipment-side devices that include multiple hybrid automatic repeat request (HARQ) modules and transmission format and resource combination selection modules, allowing for separate HARQ processes and resource allocation for each carrier, enabling flexible resource management and improved data transmission across multiple carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If single-carrier HSDPA is implemented, then device complexity is reduced, but downlink data transmission rate is limited
Solution Approach 1:
The patent divides the HSDPA service into multiple independent carrier components, where each carrier has its own HARQ module and transmission format selection module. This segmentation allows parallel data transmission across multiple carriers, increasing overall downlink data rate while maintaining manageable complexity through modular design
Solution Approach 2:
The patent creates a multi-functional MAC-hs entity that can handle both single-carrier and multi-carrier HSDPA services. The universal design allows the same basic architecture to support different carrier configurations, reducing the need for entirely separate systems and managing complexity through flexibility
2Productivity
If multi-carrier resources are managed separately, then downlink data transmission rate is improved, but resource management complexity increases
Solution Approach 1:
The patent merges the resource management functions into a unified MAC-hs entity that coordinates multiple carriers. Instead of completely separate management systems for each carrier, the merged approach allows centralized control and scheduling across all carriers, improving resource allocation efficiency while maintaining the parallel transmission benefits of multi-carrier operation
3Reliability
If multiple HARQ modules are implemented for multiple carriers, then data transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the HARQ functionality into separate modules for each carrier, allowing independent HARQ processes to operate in parallel. This segmentation improves reliability by providing redundant transmission paths across multiple carriers while managing complexity through modular, reusable module designs that can be instantiated for each carrier
