Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently coordinating multiple physical layer devices across different wireless technologies and frequency bands, leading to increased latency and complexity in establishing and managing concurrent transmissions.
Innovation Solution
A unified MAC module is introduced to coordinate multiple physical layer devices by utilizing link parameters from one physical wireless channel to establish and manage another, enabling concurrent transmissions across various PHYs, and coordinating acknowledgment packets across multiple channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple physical layer devices are coordinated independently without unified management, then each device can operate autonomously, but the system experiences increased latency and complexity in establishing and managing concurrent transmissions
Solution Approach 1:
The patent combines multiple independent physical layer devices under a unified MAC layer controller. The MAC layer acts as a central coordinating entity that manages channel access, link establishment, and transmission scheduling across multiple PHY devices, replacing independent autonomous operation with centralized unified management to reduce coordination complexity and latency.
Solution Approach 2:
The unified MAC layer implements multi-functional capabilities that serve multiple PHY devices simultaneously. It provides universal channel access control, link management, and transmission coordination functions that work across different physical layer technologies and frequency bands, enabling efficient concurrent transmissions without requiring separate management for each device.
2Loss of time
If unified MAC coordination is implemented across multiple PHYs, then latency in establishing channels is reduced and concurrent transmissions are simplified, but the system requires increased coordination overhead and control mechanisms
Solution Approach 1:
The unified MAC layer performs preliminary coordination and planning before actual transmissions occur. It pre-establishes channel access rules, link parameters, and transmission schedules for multiple PHY devices, allowing concurrent transmissions to begin immediately without repeated coordination negotiations, thereby reducing channel establishment latency while managing overhead through advance planning.
3Adaptability or versatility
If multiple wireless technologies and frequency bands are used simultaneously, then communication versatility and bandwidth are improved, but the complexity of managing different channel access functions increases
Solution Approach 1:
The unified MAC layer implements a universal channel access management mechanism that works across multiple wireless technologies and frequency bands. It provides a common framework for link establishment, maintenance, and teardown operations that adapts to different PHY-specific requirements while maintaining consistent coordination principles, thereby supporting communication versatility without proportionally increasing management complexity.

AI summary
A device implementing unified coordination of wireless communications over multiple physical layers may include a MAC module communicatively coupled to first and second physical layer modules that are each configured to communicate with another device over first and second physical wireless channels, respectively. The MAC module may be configured to provide data to the first physical layer module for transmission to the another device over the first physical wireless channel, where the first physical wireless channel is associated with a first link parameter. The MAC module may be further configured to facilitate initializing the second physical wireless channel based at least in part on the first link parameter of the first physical wireless channel, and after initialization of the second physical wireless channel, provide second data to the second physical layer module for transmission to the another device over the second physical wireless channel.
