Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the UE monitors all possible paging occasions, then paging reliability is improved, but power consumption increases

Engineering Contradiction:

Improvepaging reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The UE changes the parameter of paging occasion selection by evaluating power utilization characteristics associated with each possible paging occasion and selecting based on these characteristics, thereby optimizing the balance between monitoring reliability and power consumption

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The network node provides configuration information in advance that enables the UE to identify and select appropriate paging occasions before actual paging occurs, allowing the UE to prepare its monitoring schedule ahead of time to minimize power consumption while ensuring paging reliability

Inventive Principle:

Principle #10Preliminary action

2Use of energy by moving object

If the UE prioritizes paging occasions, then power consumption is reduced, but collision with connected mode communications may occur

Engineering Contradiction:

Improvepower consumptionVSAvoidcommunication reliability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The UE uses feedback from the network configuration information to adjust its paging occasion selection, continuously evaluating which paging occasions to monitor based on power utilization characteristics while avoiding collisions with connected mode communications

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The UE dynamically selects paging occasions based on power utilization characteristics rather than monitoring all occasions statically, adapting its monitoring behavior to current power conditions and communication requirements to prevent collisions

Inventive Principle:

Principle #15Dynamics

3Reliability

If the UE monitors multiple paging occasions, then paging detection reliability is improved, but complexity of power management increases

Engineering Contradiction:

Improvepaging detection reliabilityVSAvoidpower management complexity

Core Design Contradiction:

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying a set of possible paging occasions and a set of connected mode communications. The UE may receive paging in a paging occasion, of the set of possible paging occasions, for which there is not a collision between the paging occasion and the set of connected mode communications and that is selected from the set of possible paging occasions based at least in part on a power utilization characteristic. Numerous other aspects are described.
