QoE Configuration Handling for Inactive State Transitions

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wireless communication systems lack effective techniques for handling quality of experience (QoE) reporting when a user equipment (UE) resumes a connection from an inactive state to a base station that does not support QoE operations or cannot accommodate QoE reporting, leading to unnecessary processing resource consumption.

Innovation Solution

The UE receives QoE configurations from a first base station before entering an inactive state and performs operations based on transitioning to a connected state with a second base station, including releasing, suspending, or pausing QoE configurations depending on the second base station's support for QoE operations, ensuring efficient resource management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the UE maintains QoE configurations when transitioning from inactive state to connected state with a base station that does not support QoE operations, then QoE reporting continuity is preserved, but processing resources are consumed unnecessarily

Engineering Contradiction:

ImproveQoE reporting continuityVSAvoidprocessing resource consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The UE performs preliminary actions by checking whether the current base station supports QoE operations before resuming QoE reporting. The UE determines support capability from system information received from the base station, and based on this determination, decides whether to resume or release QoE configurations. This preliminary check prevents unnecessary resource consumption while maintaining reporting continuity when supported.

Inventive Principle:

Principle #10Preliminary action

2Use of energy by moving object

If the UE releases QoE configurations when transitioning to a base station that does not support QoE operations, then processing resources are conserved, but connection continuity is interrupted

Engineering Contradiction:

Improveprocessing resource consumptionVSAvoidconnection continuity

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The UE dynamically adjusts its QoE reporting behavior based on the capabilities of the current base station. When the base station does not support QoE operations, the UE releases QoE configurations and stops reporting. When the base station supports QoE operations, the UE resumes reporting. This dynamic adaptation allows the system to conserve resources when needed while maintaining connection continuity when supported.

Inventive Principle:

Principle #15Dynamics

3Use of energy by moving object

If the UE suspends QoE reporting when transitioning to an inactive state, then processing resources are conserved, but QoE measurement data is lost

Engineering Contradiction:

Improveprocessing resource consumptionVSAvoidQoE measurement data

Core Design Contradiction:

Use of energy by moving objectVSLoss of information

Solution Approach 1:

The UE extracts and stores QoE measurement data and configurations before transitioning to inactive state. The UE maintains QoE configurations in memory during inactive state, and when transitioning back to connected state, the UE restores these configurations if the current base station supports QoE operations. This extraction and storage mechanism conserves processing resources during inactive state while preventing data loss upon resumption.

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station prior to entering an inactive state, one or more quality of experience (QoE) configurations. The UE may perform, based at least in part on transitioning from the inactive state to a connected state with a second base station, at least one operation for the one or more QoE configurations. Numerous other aspects are described.
