Concurrent Service via Separate MAC and PHY Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices with a single MAC and PHY layer structure for wireless LAN communication systems face limitations in data throughput and delay due to the inability to perform simultaneous data reception and transmission across different frequency bands, leading to inefficient concurrent service provision.
Innovation Solution
The implementation of separate MAC and PHY layers for different frequency bands within an electronic device, allowing for concurrent signal reception and transmission across multiple frequency bands using distinct communication units, enabling independent operation and minimizing switching delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single MAC layer and PHY layer are used to support multiple frequency bands, then device complexity is reduced, but data throughput decreases and time delay increases due to time division multiplexing and frequency switching
Solution Approach 1:
The patent divides the communication module into separate MAC layers and PHY layers for different frequency bands (2.4GHz and 5GHz). Each frequency band has its own independent MAC layer and PHY layer, allowing simultaneous operation without time division multiplexing. This segmentation resolves the contradiction by sacrificing some device complexity to achieve significant improvements in data throughput and eliminate switching delays.
2Adaptability or versatility
If frequency band switching is performed between 2.4GHz and 5GHz for concurrent service, then multi-band support is achieved, but time loss occurs due to MAC layer and PHY layer switching
Solution Approach 1:
The patent creates independent MAC layers and PHY layers for each frequency band, allowing simultaneous operation on 2.4GHz and 5GHz bands without requiring switching. This eliminates the time loss associated with frequency band switching while maintaining multi-band adaptability for concurrent services.
3Device complexity
If time division multiplexing is used for signal reception and transmission, then single MAC/PHY layer structure is maintained, but maximum data throughput is decreased
Solution Approach 1:
The patent implements separate MAC layers and PHY layers for different frequency bands, enabling parallel data transmission and reception without time division multiplexing. The 2.4GHz band and 5GHz band can simultaneously transmit and receive data through their respective independent layers, maximizing data throughput while maintaining manageable device complexity through modular architecture.
4Device complexity
If a single MAC layer and PHY layer are used for concurrent service, then device structure is simplified, but real-time playback performance deteriorates due to switching delays
Solution Approach 1:
The patent creates independent MAC layers and PHY layers for 2.4GHz and 5GHz bands, allowing simultaneous operation without switching delays. This ensures reliable real-time playback performance for concurrent services such as receiving content on one band while transmitting on another, while maintaining simplified device structure through modular layer design.
