Radio Module Activity Coordination for Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multiple radio modules in wireless communication devices experience significant interference due to overlapping or adjacent radio spectrums, leading to degradation in performance and increased power consumption.
Innovation Solution
An activity coordination method is implemented, where one radio module determines and transmits indicators of adjusted traffic patterns to another radio module, allowing it to selectively skip scheduled time slots to reduce interference and conserve power, using a coexistence-signaling interface to align and negotiate RX/TX Co-Located Coexistence (CLC) bitmaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radio modules operate simultaneously in overlapping or adjacent spectrums, then wireless communication functionality is enhanced, but interference between modules increases and performance degrades
Solution Approach 1:
The patent segments the time domain into distinct slots and divides radio module operations into separate time intervals. Each radio module is assigned specific time slots for transmission and reception, preventing simultaneous operations that cause interference. This temporal segmentation allows multiple radio modules to coexist in the same device without mutual interference.
Solution Approach 2:
The patent implements dynamic traffic patterns where radio modules can flexibly adjust their transmission and reception schedules based on current communication needs. The system dynamically negotiates and modifies time slot allocations between different radio modules, allowing adaptive resource allocation that optimizes both interference avoidance and communication efficiency.
2Object-affected harmful factors
If radio modules continuously monitor and coordinate activities to reduce interference, then interference reduction is achieved, but power consumption increases
Solution Approach 1:
The patent employs periodic traffic patterns where radio modules operate in structured cycles of transmission and reception. Instead of continuous monitoring and coordination, the system uses predetermined periodic schedules that reduce the need for constant activity negotiation. Radio modules can enter low-power states during idle periods while maintaining synchronized operation patterns.
Solution Approach 2:
The patent enables radio modules to autonomously determine their own transmission and reception time slots based on pre-negotiated traffic patterns. Each radio module independently manages its schedule without requiring continuous coordination signaling, reducing the overhead and power consumption associated with constant inter-module communication.
3Object-affected harmful factors
If radio modules skip scheduled time slots to avoid interference, then interference is reduced, but scheduling efficiency decreases
Solution Approach 1:
The patent performs preliminary negotiation and coordination of traffic patterns between radio modules before actual data transmission begins. By pre-establishing compatible transmission and reception schedules, the system eliminates the need for runtime interference avoidance maneuvers. This preliminary planning ensures that time slots are optimally allocated to maximize both interference reduction and scheduling efficiency.
Solution Approach 2:
The patent implements feedback mechanisms where radio modules exchange information about their traffic patterns and operational status. This feedback enables dynamic adjustment of time slot allocations to optimize scheduling efficiency while maintaining interference avoidance. The system learns from past interactions and refines its scheduling decisions to improve overall productivity.

AI summary
A wireless communication device is provided with a first radio module and a second radio module inside. The first radio module performs wireless transceiving according to a plurality of first traffic patterns which each indicates allocations of a plurality of first slots for a plurality of forthcoming transmitting or receiving operations, respectively. The second radio module determines an indicator indicating at least one of a plurality of second traffic patterns which each indicates allocations of a plurality of second slots for a plurality of forthcoming transmitting or receiving operations, respectively. Particularly, one or more allocations of the second slots are selectively determined according to the first traffic patterns. Also, the second radio module transmits the indicator to a peer communication device, so that the peer communication device performs transmitting or receiving operations according to the indicator.
