MAC PDU Header Segmentation for Multi-Connection Payload Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current MAC PDU protocols can only accommodate information associated with one connection at a time, limiting the efficiency of broadband wireless networks and backward compatibility, as they fail to manage multiple connection information effectively.
Innovation Solution
The method involves encoding connection payload information of multiple connections in a MAC PDU using a first header for the primary connection and a second header for the remaining connections, with additional headers and fields to manage flow identifiers, lengths, and fragmentation/packing information, allowing for the multiplexing of multiple connections within the same MAC PDU.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the MAC PDU format is extended to accommodate multiple connection information, then the communication efficiency and backward compatibility are improved, but the device complexity and protocol complexity increase
Solution Approach 1:
The patent segments the connection payload information into multiple fields within the MAC PDU: a first field for the first connection payload and a second field for subsequent connection payloads. This segmentation allows the MAC PDU to handle multiple connections without fundamentally changing the overall protocol structure, thus improving versatility while controlling complexity.
Solution Approach 2:
The patent embeds multiple connection payload fields within the existing MAC PDU structure. The second connection payload field is nested within the MAC PDU after the first connection payload field, allowing multiple connections to be accommodated within the same protocol container without requiring separate protocol instances, thereby reducing the increase in device complexity.
2Productivity
If multiple connection information is multiplexed in a single MAC PDU, then the communication efficiency is improved, but the processing complexity at the receiver increases
Solution Approach 1:
The patent employs preliminary action by including a length field that specifies the length of the first connection payload. This length information is provided in advance before the actual payload data, allowing the receiver to efficiently process and identify the boundaries of different connection payloads without complex parsing operations, thus improving communication efficiency while keeping processing complexity manageable.
3Reliability
If the existing MAC PDU format is maintained for backward compatibility, then system compatibility is improved, but the capability to handle multiple connections is limited
Solution Approach 1:
The patent applies universality by designing the MAC PDU to serve multiple functions: it can accommodate a single connection payload using the existing format for backward compatibility, and simultaneously accommodate multiple connection payloads by utilizing the extended field structure. This multi-functionality allows the same MAC PDU format to maintain backward compatibility while enabling enhanced multi-connection capability.
