QoE-Based Source and Radio Parameter Coordination for Variable Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to dynamically adjust payload parameters and network configurations based on dynamic channel conditions and varying user experiences, leading to inconsistent quality of experience (QoE) for users.
Innovation Solution
Implementing a Source and Radio Parameter Selection Service (S&RPS) that receives information on source encoding parameters, link conditions, and user experiences to dynamically adjust source and network configuration parameters, allowing for real-time adjustments to maintain optimal QoE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication systems use fixed payload parameters and network configurations, then system complexity is reduced, but quality of experience becomes inconsistent under varying channel conditions
Solution Approach 1:
The patent implements dynamic parameter adjustment by introducing a parameter configuration network element that receives feedback information about channel conditions and user equipment status, then dynamically adjusts payload parameters (such as encoding rate, packet size) and network configuration parameters (such as resource allocation, scheduling policies) in real-time to maintain consistent quality of experience across varying conditions
Solution Approach 2:
The system establishes a feedback mechanism where user equipment reports channel quality indicators and experience metrics to the parameter configuration network element, which then uses this feedback to continuously optimize parameter settings, creating a closed-loop control system that adapts to changing conditions while maintaining QoE consistency
2Reliability
If the system dynamically adjusts payload parameters and network configurations based on channel conditions, then quality of experience is improved, but system complexity increases
Solution Approach 1:
The patent introduces a dedicated parameter configuration network element as an intermediary between the core network and user equipment. This intermediary consolidates the complexity of dynamic parameter adjustment logic in a centralized location, managing both payload parameters and network configuration parameters through coordinated control, thereby improving QoE while containing system complexity within a specific component rather than distributing it across the entire system
3Adaptability or versatility
If fixed network configurations are used, then ease of operation is maintained, but adaptability to different channel conditions deteriorates
Solution Approach 1:
The system implements self-service operation by enabling automatic parameter optimization through the parameter configuration network element that autonomously receives feedback, processes channel condition information, and adjusts parameters without requiring manual intervention. This maintains ease of operation while achieving high adaptability, as the system self-adjusts to different conditions through automated feedback-driven control

AI summary
Methods, systems, and devices for wireless communications are described. A source and radio parameter service (S&RPS) of a wireless communications service may receive one or more inputs, including source encoding parameters from a source entity, link condition information from a radio access network (RAN), measurement reports from the one or more user equipments (UEs), or any combination thereof. The S&RPS may output one or more outputs including source configuration parameters for the source entity to encode application data for the UEs, network configuration parameters for the RAN to communicate the application data to the UEs, or both. The S&RPS may also obtain QoE thresholds for the UEs, and may determine the outputs based on the QoE thresholds and the inputs. The S&RPS may also configure the UEs, the RAN, or both, with respective measurement configurations, and the inputs may be based on the respective measurement configurations.
