Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in communication systems is effectively configuring FDSS parameters across diverse uplink transmission scenarios to maintain optimal system performance, as performance gains vary with modulation schemes and scheduling configurations.
Innovation Solution
A User Equipment (UE) dynamically configures FDSS-related parameters based on first information, including association relationships, indication information, or signal measurement values, to optimize FDSS-based uplink transmission and reduce Peak-to-Average Power Ratio (PAPR).

Engineering Contradiction Analysis
1Reliability
If a shaping filter (FDSS filter) is introduced to reduce PAPR, then transmission power can be increased and demodulation performance improved, but transmission power at edges of allocated frequency band is reduced, degrading overall system performance
Solution Approach 1:
The patent dynamically adjusts FDSS parameters (such as filter coefficients, bandwidth, or shaping factors) based on current transmission conditions and signal characteristics. This allows the system to optimize the balance between PAPR reduction and edge power preservation by changing filter parameters adaptively rather than using fixed parameters, thereby maintaining demodulation performance while minimizing power loss at frequency band edges.
Solution Approach 2:
The patent implements dynamic configuration of FDSS parameters that can change in real-time according to transmission requirements. The system monitors transmission conditions and adjusts FDSS parameters dynamically, enabling the shaping filter to adapt its characteristics to preserve edge power while maintaining PAPR reduction benefits, thus resolving the contradiction between demodulation performance and transmission power at frequency edges.
2Reliability
If FDSS parameters are configured statically, then system complexity is reduced, but optimal system performance cannot be maintained across diverse uplink transmission scenarios
Solution Approach 1:
The patent employs feedback mechanisms where the system monitors transmission performance and channel conditions, then uses this information to dynamically adjust FDSS parameters. The feedback loop enables the system to automatically optimize parameters for current transmission scenarios, maintaining high system performance across diverse conditions without requiring complex manual configuration, as the system self-adjusts based on observed performance metrics.
Solution Approach 2:
The patent implements self-service mechanisms where the FDSS parameter configuration system automatically adapts to different transmission scenarios without external intervention. The system uses built-in monitoring and decision-making capabilities to select appropriate parameters based on current conditions, reducing the need for complex external configuration while maintaining optimal performance across varying uplink transmission scenarios.

AI summary
A FDSS parameter configuration method includes obtaining, by a User Equipment (UE), first information, and dynamically switching or configuring, by the UE, an FDSS-related parameter based on the first information. The FDSS-related parameter is a parameter used for performing FDSS-based uplink transmission. The first information includes at least one of the following: an association relationship between the FDSS-related parameter and a first parameter, the first parameter being a parameter used for performing uplink transmission; a first indication information, wherein the first indication information is used for indicating the FDSS-related parameter that needs to be dynamically switched or configured; or a signal measurement value or a signal statistics value.
