Dynamic MSD Determination for Wireless Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems allocate resources based on static Maximum Sensitivity Degradation (MSD) values, which can lead to suboptimal spectrum and network resource allocations due to varying receiver sensitivity among user equipment (UE) models, resulting in inefficient use of resources and potential loss of cell coverage.
Innovation Solution
User equipment (UE) is configured to autonomously determine its MSD value in real-time, considering UE-specific parameters and dynamic 3GPP parameters, and provide this value to the network, allowing for more efficient allocation of spectrum and network resources based on actual sensitivity levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static MSD values are used for resource allocation, then system complexity is reduced, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent implements dynamic MSD determination where the MSD value is no longer static but changes based on real-time receiver sensitivity measurements. The system continuously monitors actual sensitivity levels and updates the MSD parameter accordingly, allowing resource allocation to adapt to varying channel conditions, UE-specific characteristics, and interference environments. This dynamic approach resolves the contradiction by making the allocation system responsive without excessive complexity.
Solution Approach 2:
The patent introduces a feedback mechanism where the network receives actual sensitivity measurements from UEs and uses this information to adjust resource allocation decisions. The UE reports measured sensitivity values to the network, which then determines appropriate MSD values for scheduling and resource allocation. This closed-loop feedback system enables efficient resource allocation based on actual conditions while maintaining manageable system complexity through standardized feedback procedures.
2Measurement precision
If UE-specific MSD values are determined autonomously, then resource allocation precision is improved, but UE complexity increases
Solution Approach 1:
The patent enables UEs to autonomously determine their own MSD values by performing self-measurements of receiver sensitivity. Each UE independently measures its actual sensitivity under current operating conditions and reports this value to the network without requiring complex external calibration or configuration. This self-service approach improves measurement precision while keeping UE complexity manageable by leveraging existing measurement capabilities within the UE architecture.
Solution Approach 2:
The patent changes the MSD parameter from a fixed, pre-configured value to a dynamically determined value based on actual receiver sensitivity measurements. The UE measures sensitivity parameters such as noise floor, interference levels, and signal strength, then uses these measurements to determine an appropriate MSD value that reflects current operating conditions. This parameter change approach enables precise, UE-specific resource allocation while using straightforward measurement and calculation procedures.
3Adaptability or versatility
If real-time MSD determination is implemented, then system adaptability is improved, but processing overhead increases
Solution Approach 1:
The patent implements periodic MSD determination where UEs measure and report sensitivity values at scheduled intervals rather than continuously. The network can configure the reporting periodicity based on channel conditions and service requirements. This periodic approach provides timely updates for resource allocation decisions while avoiding excessive processing overhead from continuous measurements and reporting, thus balancing adaptability with processing efficiency.

AI summary
Systems and methods for better utilizing available resources within a wireless telecommunication system. One aspect of the present invention is user equipment (UE) configured to autonomously determine its Maximum Sensitivity Degradation (MSD) value for a particular UE configuration. The MSD value is a function of (1) selected UE-specific parameters, such as those that are determined by the characteristics of the UE's RFFE components and RFFE architecture, and (2) selected standard parameters that may be dynamic or vary over time. Another aspect of the present invention is to configure a UE to provide its determined MSD value to a communications network, either as a raw value or as a computed indication of the MSD value relative to a specified reference value. The determined MSD value may then be used by a system controller to select a more efficient allocation of spectrum and network resources.
