MAC Super-Frame Payload for Wireless Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, such as IEEE 802.11, face challenges in improving communication throughput due to overhead limitations in frame formats, particularly in physical layer protocols, which restrict the efficiency of data transmission and error tolerance when attempting to achieve higher data rates.
Innovation Solution
The proposed solution involves a communication apparatus that constructs physical frames with a medium access super-frame payload containing multiple medium access control frames, where virtual carrier sense information is set to ensure identical carrier sense results across frames, allowing for efficient transmission and improved throughput by integrating multiple MAC frames into a single PHY frame, thereby reducing overhead and enhancing error tolerance.

Engineering Contradiction Analysis
1Productivity
If multiple MAC frames are transmitted separately in existing IEEE 802.11 systems, then each frame can be transmitted with standard PHY frame format, but the overhead increases and throughput decreases
Solution Approach 1:
The patent combines multiple MAC frames into a single PHY frame structure, creating a MAC super-frame that aggregates multiple medium access control frames within one physical layer frame. This merging reduces the number of separate PHY frame transmissions, thereby reducing overall overhead and improving communication throughput while maintaining backward compatibility with existing IEEE 802.11 systems.
2Speed
If physical layer protocol is changed to achieve higher data rate, then communication speed improves, but frame format overhead increases and error tolerance decreases
Solution Approach 1:
The patent segments the MAC layer into multiple independent MAC frames that can be individually error-checked and managed, while these segmented frames are transmitted together within a single PHY frame. This segmentation allows for better error control and tolerance at the MAC layer while maintaining the high data rate capabilities of the physical layer protocol.
3Adaptability or versatility
If virtual carrier sense information is set to ensure identical carrier sense results, then coexistence with existing systems is enabled, but frame format complexity increases
Solution Approach 1:
The patent creates a universal MAC super-frame format that can be interpreted by both legacy IEEE 802.11 devices and new high-speed devices. The virtual carrier sense information is set to ensure identical carrier sense results across different device types, enabling coexistence. The frame format is designed to be multi-functional, supporting both backward compatibility and new features without requiring separate formats for different device generations.
Data Source
AI summary
A physical frame is constructed, the physical frame including a medium access control super-frame payload which in turn includes a plurality of medium access control frames. With respect to the constructed physical frame, virtual carrier sense information is set in the plurality of medium access control frame so that a result of carrier sense is identical to another by virtual carrier sense based on the plurality of medium access control frames in the medium access control super-frame payload. The physical frame in which the virtual carrier sense information has been set is transmitted to a destined communication apparatus.
