Radio Module Timing Coordination for Wireless Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of multiple wireless communications services in mobile devices, such as Bluetooth, Wi-Fi, and WiMAX, leads to transmission interference due to overlapping or adjacent frequency bands, resulting in degraded performance and inefficient bandwidth utilization.
Innovation Solution
A method where one radio module estimates the time remaining before its next operation and transmits this information to another module, allowing the receiving module to schedule its operations accordingly to avoid traffic collisions and optimize transmission windows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless communications services (Bluetooth, Wi-Fi, WiMAX) are integrated in a mobile device, then the device can provide diverse wireless communication capabilities, but transmission interference occurs due to overlapping or adjacent frequency bands
Solution Approach 1:
The patent applies preliminary action by having one radio module estimate and transmit information about its next operation timing to another radio module in advance. This allows the receiving module to proactively schedule its operations to avoid interference, rather than reacting after interference occurs. The key mechanism is the estimation of remaining time until the next transmission/reception operation and communicating this timing information between modules.
Solution Approach 2:
The patent implements feedback by having radio modules exchange information about their operation timing with each other. Each module provides feedback about its scheduled operations to other modules, enabling them to adjust their scheduling accordingly. This creates a closed-loop system where modules continuously share timing information to coordinate their operations and avoid frequency band conflicts.
2Productivity
If simultaneous transmission and reception by different wireless communications services occur, then communication efficiency is reduced, but providing multiple services simultaneously is necessary for device functionality
Solution Approach 1:
The patent applies dynamics by implementing flexible and adaptive scheduling of radio module operations. Instead of fixed scheduling, modules dynamically adjust their transmission and reception timing based on real-time operation information exchanged with other modules. This dynamic scheduling allows the system to optimize communication efficiency while maintaining multi-service capability, as modules can adapt their operations to avoid conflicts.
3Quantity of substance
If frequency bands of different wireless services overlap or are adjacent, then spectrum utilization is improved, but transmission performance degrades due to interference
Solution Approach 1:
The patent applies preliminary action by having radio modules estimate and communicate their next operation timing in advance. This allows other modules to proactively schedule their operations to avoid overlapping with high-utilization periods, thereby maintaining reliable transmission performance while maximizing spectrum utilization across multiple services.

AI summary
A method for coordinating transmission and reception operations of a first and a second radio module in a communications apparatus, the first radio module communicating with a first communications device in a first protocol to provide a first wireless communications service and the second radio module communicating with a second communications device in a second protocol to provide a second wireless communications service. The method includes estimating, by the first radio module, time remaining for the second radio module; receiving, by the second radio module, information regarding the estimated remaining time from the first radio module; determining, by the second radio module, whether time required for the operations of the second radio module exceeds the estimated remaining time; and scheduling, by the second radio module, operations of the second radio module according to the information regarding the estimated remaining time received from the first radio module.
