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 selectively skips scheduled time slots to reduce interference and save power, using a coexistence-signaling interface to align and adjust communication slots based on the traffic patterns of co-located radio modules, generating RX/TX CLC bitmaps to negotiate and optimize data transmission and reception.
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 for different radio modules. Each radio module is assigned specific time slots for transmission and reception, preventing simultaneous operation in overlapping spectrums. This time-division multiplexing approach allows multiple radio modules to coexist without interference while maintaining their communication functionality.
Solution Approach 2:
The patent implements periodic time-division schedules where radio modules alternate between transmission and reception phases in a cyclic manner. Each radio module follows a periodic pattern of active and inactive periods, ensuring that when one module transmits, others are in reception or idle states, thereby eliminating mutual interference while preserving continuous communication capability.
2Productivity
If radio modules perform scheduled transmitting and receiving operations in overlapping time slots, then data communication efficiency is improved, but power consumption increases due to continuous operation
Solution Approach 1:
The patent ensures continuous useful action by carefully coordinating the time slots of multiple radio modules so that transmission and reception operations are continuously scheduled without idle gaps. Each module has back-to-back transmission and reception slots that fully utilize its operational capacity, maintaining high data communication efficiency while avoiding unnecessary idle power consumption.
Solution Approach 2:
The patent allows radio modules to skip scheduled time slots when interference is detected or when the other module is actively transmitting in a conflicting spectrum. By selectively skipping non-critical reception slots or low-priority transmission slots, the system reduces power consumption during periods of inevitable interference while maintaining overall communication efficiency through compensation mechanisms.
3Area of stationary object
If radio modules use overlapping radio spectrums, then device compactness is improved, but signal interference and reception quality deteriorate
Solution Approach 1:
The patent segments the spectrum usage by assigning different frequency bands or spectrum portions to different radio modules during their respective time slots. This spectral segmentation combined with time-division multiplexing allows compact device design with co-located antennas while maintaining signal reception quality by preventing simultaneous spectrum overlap.
Solution Approach 2:
The patent introduces a coordination mechanism that acts as an intermediary between multiple radio modules, managing their spectrum and time slot assignments. This mediator ensures that spectrum usage is optimized for compact device design while preventing interference that would degrade reception quality, by dynamically adjusting time slot allocations based on detected interference conditions.

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.
