Wireless Module Coexistence Control for Shared RF Resource Contention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies struggle to efficiently manage coexistence interference among multiple communication protocols in a single chip, particularly in terms of circuit resource contention, and existing solutions are limited in flexibility and applicability.
Innovation Solution
A method and apparatus that utilize a coexistence controller to group wireless communication modules based on circuit resource contention, prioritize communication services, and allocate coexistence grants to ensure only one module transmits at a time while allowing others to receive, thereby managing circuit resource conflicts.

Engineering Contradiction Analysis
1Object-affected harmful factors
If antenna design is optimized for each communication module, then interference between independent modules is reduced, but channel interference among multi-mode communication modes in a single chip cannot be solved
Solution Approach 1:
A coexistence controller is introduced as an intermediary component to manage resource allocation among multiple communication modules. The controller receives allocation requests from various modules, determines allocation results based on priority rules, and controls the shared RF transceiver circuit to serve different modules in different time periods, thereby solving the resource contention problem in single-chip multi-mode communication
2Object-affected harmful factors
If frequency domain avoidance is used, then channel resource contention among frequency-hopping protocols is minimized, but RF circuit resource contention cannot be solved
Solution Approach 1:
The patent implements dynamic time-domain resource allocation where the RF transceiver circuit switches between serving different communication modules based on time-division multiplexing. The coexistence controller dynamically determines which module should access the shared circuit at any given time period, transforming the static frequency-avoidance approach into a dynamic time-sharing mechanism that handles RF circuit contention
3Productivity
If time domain avoidance through time-division communication is used, then resource sharing among multiple modules is solved, but the solution lacks flexibility and real-time performance
Solution Approach 1:
The patent segments the time domain into multiple time periods and further divides the resource allocation into two independent dimensions: transmission priority (for transmitting modules) and reception priority (for receiving modules). This segmentation allows flexible combination of different priority levels within each time period, enabling the system to adapt to various communication scenarios while maintaining efficient resource utilization
