Adaptive Uplink MCS Control for Wireless Interference Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing uplink interference in wireless communication networks do not effectively consider individual Mobile Stations' interference criteria, leading to suboptimal Modulation and Coding Scheme (MCS) levels and a tradeoff between power control and signal quality.
Innovation Solution
A method that selects Mobile Stations based on signal parameters associated with serving and neighboring Base Stations, using threshold parameters to modify MCS levels adaptively, thereby reducing interference and optimizing power usage.

Engineering Contradiction Analysis
1Reliability
If a higher MCS scheme is selected to improve uplink quality, then signal quality is improved, but transmission power and overall uplink interference increase
Solution Approach 1:
The patent applies local quality by differentiating MCS level modification based on individual MS interference characteristics. Instead of uniformly lowering MCS for all MSs, the system identifies specific MSs that cause excessive interference and modifies their MCS levels selectively, while maintaining higher MCS levels for MSs with lower interference output. This localized approach preserves signal quality for most users while controlling interference from problematic MSs.
Solution Approach 2:
The patent changes the MCS level parameter dynamically based on measured interference characteristics. The system modifies the MCS level parameter for selected MSs to achieve a balance between maintaining adequate signal quality and reducing uplink interference. This parameter modification is done adaptively based on real-time interference measurements and MS-specific criteria.
2Object-generated harmful factors
If transmission power is reduced to lower uplink interference, then overall uplink interference decreases, but signal quality deteriorates
Solution Approach 1:
The patent applies local quality by differentiating MCS level modification based on individual MS interference characteristics. Instead of uniformly lowering MCS for all MSs, the system identifies specific MSs that cause excessive interference and modifies their MCS levels selectively, while maintaining higher MCS levels for MSs with lower interference output. This localized approach preserves signal quality for most users while controlling interference from problematic MSs.
Solution Approach 2:
The patent employs feedback mechanisms where the Base Station continuously monitors uplink interference characteristics and uses this information to adjust MCS levels. The system receives feedback about interference levels and adapts MCS assignments accordingly, creating a closed-loop control system that balances signal quality and interference reduction dynamically.
3Object-generated harmful factors
If MCS level is lowered for all MSs to control interference, then uplink interference is reduced, but network throughput decreases
Solution Approach 1:
The patent applies local quality by differentiating MCS level modification based on individual MS interference characteristics. Instead of uniformly lowering MCS for all MSs, the system identifies specific MSs that cause excessive interference and modifies their MCS levels selectively, while maintaining higher MCS levels for MSs with lower interference output. This localized approach preserves signal quality for most users while controlling interference from problematic MSs.
Solution Approach 2:
The patent segments the MS population into different groups based on their interference characteristics. The system divides MSs into those that cause excessive interference and those that do not, applying different MCS level strategies to each segment. This segmentation allows the system to optimize interference control for problematic MSs while maintaining high throughput for the majority of MSs.

AI summary
A method for managing uplink communication in wireless communication network is provided. The method includes selecting one or more Mobile Stations (MSs) from a plurality of MSs based on a first signal parameter corresponding to each MS of the one or more MSs, one or more second signal parameters corresponding to each MS of the one or more MSs, and one or more threshold parameters. The first signal parameter is associated with a Base Station (BS) serving a MS. Further, the one or more second signal parameters are associated with one or more BSs neighboring to the MS. The one or more threshold parameters are associated with a communication parameter. Thereafter, the method includes modifying uplink Modulation and Coding Scheme (MCS) level of the one or more MSs.
