Dynamic Bandwidth Part Allocation for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless telecommunications networks face challenges in dynamically managing bandwidth parts (BWP) allocations, leading to inadequate flexibility and performance, especially when network usage exceeds initial allocation thresholds, resulting in reduced power consumption benefits and increased signaling overhead.
Innovation Solution
Implementing a method and system for dynamically adjusting BWP allocations by setting usage thresholds and monitoring parameters, allowing for the configuration or modification of BWPs in response to changing usage conditions, such as overutilization or frequent UE switching, to optimize resource utilization and spectral efficiency.

1Productivity
If BWP allocation is dynamically adjusted in response to usage threshold exceedance, then network resource utilization and spectral efficiency are improved, but system complexity and signaling overhead increase
Solution Approach 1:
The patent implements dynamic BWP allocation by allowing the network to adjust bandwidth part configurations in real-time based on monitored usage parameters. When usage thresholds are exceeded, the system dynamically reconfigures BWP allocations for affected UEs, transforming the static resource allocation into an adaptive system that responds to changing network conditions, thereby improving resource utilization without requiring complete system redesign
Solution Approach 2:
The system changes key parameters such as BWP bandwidth, frequency location, and resource block allocation based on monitored usage conditions. By adjusting these parameters dynamically when thresholds are exceeded, the network optimizes spectral efficiency and resource utilization while maintaining compatibility with existing NR protocols and minimizing the need for complex architectural changes
2Reliability
If BWP allocation is dynamically adjusted to handle overutilization, then network performance is improved, but signaling overhead increases
Solution Approach 1:
The patent implements a feedback mechanism where the network monitors usage parameters for each BWP and compares them against configured thresholds. When thresholds are exceeded, the system generates appropriate signaling to adjust BWP allocations. This feedback-driven approach ensures that signaling is triggered only when necessary, improving network performance while minimizing unnecessary signaling overhead by responding selectively to actual usage conditions
Solution Approach 2:
The system applies partial adjustment by modifying only the specific BWP allocations that exceed usage thresholds rather than reconfiguring all BWP assignments in the network. This selective approach improves network performance where needed while limiting signaling overhead to only the affected UEs and BWPs, avoiding unnecessary full-system reconfiguration
3Device complexity
If fixed BWP allocation is used, then system complexity is reduced, but adaptability to changing usage conditions deteriorates
Solution Approach 1:
The patent transforms the static BWP allocation system into a dynamic one by introducing threshold-based monitoring and conditional reconfiguration. The system maintains simple baseline configurations but automatically adapts when usage parameters exceed thresholds, providing the flexibility needed for changing network conditions while preserving the simplicity of the underlying allocation structure for normal operations
