Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing media access control (MAC) layer architecture in mobile communication technologies faces challenges in efficiently managing and processing data for various bearer sets, which are essential for providing better services in future mobile communication systems with multiple numerologies.
Innovation Solution
A network-side and terminal-side media access control layer architecture is designed, comprising a common scheduling function unit, dedicated scheduling function units, and multiplexing and retransmission function units, which determine resource allocation and prioritize bearers to enable efficient data transmission across multiple bearer sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional MAC layer architecture is used, then the system structure is simple, but it cannot efficiently manage and process data for various bearer sets with multiple numerologies
Solution Approach 1:
The MAC layer architecture is segmented into multiple MAC entities, with each MAC entity managing a specific bearer set. This segmentation allows each MAC entity to independently handle scheduling, multiplexing, and retransmission for its assigned bearer set, enabling efficient management of multiple numerologies while maintaining clear functional boundaries.
Solution Approach 2:
Each MAC entity is designed with multi-functional capabilities including scheduling function, multiplexing function, and retransmission function. This universal design within each MAC entity allows the system to handle diverse bearer set requirements using the same functional building blocks, improving adaptability without proportionally increasing overall complexity.
2Productivity
If multiple MAC entities are introduced to manage different bearer sets, then data processing efficiency for multiple bearer sets improves, but the system complexity increases
Solution Approach 1:
The MAC layer is divided into multiple independent MAC entities, each responsible for a specific bearer set. This segmentation enables parallel processing of data from different bearer sets, significantly improving data processing efficiency. Each MAC entity can independently perform scheduling decisions, multiplexing operations, and retransmission management without interfering with other bearer sets.
Solution Approach 2:
A bearer set identifier is introduced as an intermediary parameter to manage the interaction between multiple MAC entities and the upper layers. This identifier enables efficient routing and association of data with the appropriate MAC entity, reducing the overhead of managing multiple entities and mitigating the complexity increase.
3Measurement precision
If dedicated scheduling function units are assigned to each bearer set, then resource allocation accuracy improves, but the complexity of resource management increases
Solution Approach 1:
Each MAC entity implements dedicated scheduling function units that are locally optimized for its specific bearer set characteristics. This local quality approach allows each scheduler to make precise resource allocation decisions tailored to the specific requirements of its bearer set, improving resource allocation accuracy while distributing the management complexity across multiple independent units rather than requiring a single complex centralized scheduler.
