Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods in wireless local area networks heavily depend on the storage space of wireless communication apparatuses to determine the aggregation number of data frames, leading to limited throughput and increased storage requirements.
Innovation Solution
A data transmission method where the primary apparatus determines the aggregation number of data frames based on a negotiated threshold value, independent of the wireless communication apparatus's storage space, and uses a first-in-first-out caching area to manage and transmit the frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wireless communication apparatus determines the aggregation number based on its storage space, then the aggregation number is limited by storage capacity, but this approach increases dependence on storage space size and limits throughput
Solution Approach 1:
The patent inverts the traditional approach by having the primary apparatus (instead of the wireless communication apparatus) determine and notify the aggregation number to the wireless communication apparatus. This inversion transfers the decision-making authority from the storage-constrained device to the primary apparatus, allowing throughput optimization without being limited by the wireless communication apparatus's storage capacity. The primary apparatus calculates the optimal aggregation number and communicates it via attribute information, enabling the wireless communication apparatus to aggregate frames efficiently regardless of its storage constraints.
2Ease of operation
If the wireless communication apparatus aggregates data frames when receiving the determined aggregation number, then aggregation processing can be performed, but large storage space is required to store the data frames
Solution Approach 1:
The patent applies preliminary action by having the primary apparatus pre-determine and notify the aggregation number before the wireless communication apparatus performs aggregation. The attribute information containing the aggregation number is transmitted in advance, allowing the wireless communication apparatus to prepare for aggregation without needing to store all potential data frames. This preliminary notification enables the wireless communication apparatus to manage its storage more efficiently by knowing in advance how many frames to aggregate, reducing the peak storage requirement.
3Adaptability or versatility
If the aggregation number is determined by the wireless communication apparatus based on storage space, then the system can adapt to storage constraints, but throughput is severely limited
Solution Approach 1:
The patent changes the key parameter of aggregation number determination from being storage-dependent to being throughput-optimized. The primary apparatus calculates the optimal aggregation number based on throughput requirements and notifies it to the wireless communication apparatus via attribute information. This parameter change allows the system to maintain adaptability while breaking the direct dependency between aggregation number and storage space, thereby enabling higher throughput without proportionally increasing storage requirements.
