BWP Switching via Duplex Mode Timers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face interference and performance degradation due to increasing demand for mobile broadband access, leading to congested networks and inefficient use of resources, particularly in full duplex operations where simultaneous uplink and downlink transmissions cause self-interference.
Innovation Solution
Implementing a method that uses multiple timers to switch between half duplex and full duplex bandwidth part (BWP) configurations, allowing wireless devices to adapt their operation based on BWP inactivity and duplex mode timers, thereby optimizing resource usage and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If full duplex operation is implemented to increase network capacity and throughput, then productivity is improved, but self-interference and performance degradation occur
Solution Approach 1:
The patent implements dynamic switching between full duplex and half duplex BWP configurations based on timer expiration and interference conditions. The system transitions from static duplex mode to dynamic adaptation, allowing the network to optimize between capacity and interference management in real-time based on channel conditions and traffic demands.
Solution Approach 2:
The patent changes the operational parameters by switching between different BWP configurations with distinct duplex modes. By modifying the duplex mode parameter (full vs half) and timing parameters (timer values), the system adjusts network operation to balance capacity utilization against self-interference levels.
2Adaptability or versatility
If multiple timers are implemented to manage BWP switching, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent segments the timer management into multiple independent timers (first timer for full duplex, second timer for half duplex) that can be configured and expire independently. This segmentation allows flexible adaptation to different traffic patterns and interference conditions while keeping each timer's function simple and well-defined.
Solution Approach 2:
The timer mechanism serves multiple functions: it tracks inactivity periods, triggers BWP switching, and adapts to changing channel conditions. The same timer infrastructure is used for both full duplex and half duplex mode management, providing a universal control mechanism that handles various adaptation scenarios.
3Object-generated harmful factors
If dynamic switching between BWP configurations is implemented to reduce interference, then loss of harmful factors is improved, but device complexity increases
Solution Approach 1:
The patent employs periodic timer-based switching between BWP configurations to manage self-interference. Instead of continuous complex interference measurement and adjustment, the system uses periodic timer expiration events to trigger controlled switching between full and half duplex modes, simplifying the switching mechanism while maintaining interference reduction effectiveness.

AI summary
Bandwidth part (BWP) inactivity and mode switching supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. A wireless device may be provided with multiple BWP configurations, such as may include a default half duplex BWP configuration and a default BWP configuration. Multiple timers, such as may include a BWP inactivity timer and a duplex mode timer, may be implemented for timer-based switching between BWP configurations, such as any combination of a default half duplex BWP configuration, an active half duplex BWP configuration, a default full duplex BWP configuration, and an active full duplex BWP configuration. Other aspects and features are also claimed and described.
