Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing sidelink communications using multiple radio access technologies, as they often rely on a single protocol stack that cannot effectively handle diverse communication needs.
Innovation Solution
Implementing a method and apparatus that assign separate protocol stacks for network and sidelink communications, allowing for the generation and transmission of information based on data arrival in sidelink logical channels using multiple protocol stacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single protocol stack is used for both network and sidelink communications, then device complexity is reduced, but the system cannot effectively handle diverse communication needs of different radio access technologies
Solution Approach 1:
The patent divides the protocol stack into separate instances: a first protocol stack dedicated to network communications and a second protocol stack dedicated to sidelink communications. This segmentation allows each protocol stack to be optimized for its specific communication type and radio access technology without interfering with the other, thereby handling diverse communication needs while maintaining manageable complexity through functional separation.
2Adaptability or versatility
If separate protocol stacks are assigned for network and sidelink communications, then communication capabilities are enhanced, but device complexity increases
Solution Approach 1:
By segmenting the protocol stack into separate instances for network and sidelink communications, the patent enables independent optimization and management of each communication type. The network protocol stack handles traditional cellular communications while the sidelink protocol stack manages direct device-to-device communications, allowing enhanced capabilities without requiring a completely new integrated system.
Solution Approach 2:
The patent introduces an intermediary mechanism where the first protocol stack can forward data to the second protocol stack, which then transmits it over the sidelink. This intermediary approach allows seamless integration between different protocol stacks, enabling complex multi-technology communications while maintaining clear separation and manageable complexity through defined interfaces and data flow paths.
3Adaptability or versatility
If multiple protocol stacks are used simultaneously, then resource management flexibility is improved, but information management complexity increases
Solution Approach 1:
The patent employs the first protocol stack as an intermediary that receives data from upper layers and forwards it to the second protocol stack for sidelink transmission. This intermediary role simplifies information management by providing a clear data flow path and interface between protocol stacks, reducing the complexity of managing multiple protocol instances while maintaining flexible resource allocation across different communication types.
