Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in maintaining consistent quality of service across different wireless communication systems due to varying data rates, which are not dynamically adjusted based on user device measurements, leading to inconsistent service levels.
Innovation Solution
A method and system for dynamic data rate selection, where an access point and base station maintain power-data rate tables that are shared and updated based on user device measurements, with verification and adjustment processes to ensure optimal data rates, allowing for consistent service levels across different wireless communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different wireless communication systems use different received power level to data rate classification, then each system can optimize for its own characteristics, but quality of service becomes inconsistent across systems
Solution Approach 1:
The patent creates a unified power-data rate table that serves both WiFi and cellular systems, allowing the same table to be used across different wireless communication systems. This universal table maps received power levels to appropriate data rates in a consistent manner, enabling multi-functionality across system boundaries while maintaining QoS consistency.
Solution Approach 2:
The system dynamically adjusts data rate parameters based on measured received power levels by referencing the unified power-data rate table. Instead of using fixed system-specific classifications, the data rate parameter is changed dynamically according to the actual channel conditions and the unified mapping, ensuring consistent QoS across different wireless systems.
2Productivity
If dynamic rate selection techniques are used to account for channel quality, then data rate adapts to channel conditions, but service level inconsistency persists across different wireless systems
Solution Approach 1:
The system implements a feedback mechanism where user devices report measured received power levels to the network controller. The controller uses this feedback to query the unified power-data rate table and determine the appropriate data rate, creating a closed-loop system that adapts to channel conditions while maintaining consistency across different wireless systems through the unified mapping approach.
Solution Approach 2:
The patent merges the previously separate power-data rate classification mechanisms of different wireless systems into a single unified power-data rate table. This combining of separate systems into one unified approach allows dynamic rate selection based on channel quality while ensuring service level consistency across all wireless communication systems.
3Device complexity
If fixed throughput per power level is used in downlink, then system complexity is reduced, but quality of service varies with distance and channel conditions
Solution Approach 1:
The patent transforms the static fixed throughput per power level configuration into a dynamic system where the data rate is selected based on real-time received power level measurements. The unified power-data rate table provides a dynamic mapping that adapts to changing channel conditions and distance, ensuring consistent quality of service while maintaining manageable system complexity through the use of a pre-defined lookup table.
Data Source
AI summary
Dynamic data rate selection in wireless networks is described. The includes sending, by a wireless controller to a base station, an access point power-data rate table. The base station updates a base station power-data rate table with the access point power-data rate table based on checking defined thresholds, confirms the validity of the updated base station power-data rate table by receiving measurements from a user device responsive to communications using the updated base station power-data rate table, reverts to a previous base station power-data rate table if the measurements indicate that the updated base station power-data rate table is not correct, and sends to the wireless controller one of the updated base station power-data rate table or the previous base station power-data rate table. The wireless controller updates the access point power-data rate table and sends the updated access point power-data rate table to an access point.
