Solution Overview

Problem

Existing wireless networks face significant overhead and energy consumption issues due to frequent beam measurements and reporting in beam-based communications, particularly in high mobility scenarios and multi-input multi-output transmissions.

Innovation Solution

Implement event-triggered operations in beam-based communication by configuring apparatuses with specific event triggering information based on sensing and beam measurement information, allowing actions to be performed only when predefined conditions are met, thereby reducing unnecessary measurements and reports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If frequent beam measurements and reporting are performed, then beam management accuracy is improved, but transmission overhead increases

Engineering Contradiction:

Improvebeam measurement accuracyVSAvoidtransmission overhead

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent implements event-triggered beam measurement and reporting where UEs perform measurements and send reports only when specific events occur (beam failure, handover, beam switching) rather than continuously or periodically. This reduces transmission overhead while maintaining necessary measurement accuracy for beam management operations.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent dynamically adjusts measurement and reporting parameters based on UE mobility states, beam conditions, and network configurations. By changing measurement frequency, reporting thresholds, and trigger conditions according to actual network conditions, the system optimizes the balance between measurement accuracy and overhead reduction.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If frequent beam measurements and reporting are performed, then beam management accuracy is improved, but energy consumption increases

Engineering Contradiction:

Improvebeam measurement accuracyVSAvoidenergy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The event-triggered mechanism eliminates continuous periodic measurements and reporting, requiring UEs to activate measurement and reporting functions only when specific events occur. This significantly reduces energy consumption for beam management operations while maintaining measurement accuracy when needed.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The UE autonomously determines when to perform beam measurements and send reports based on locally evaluated event conditions (beam failure detection, handover events, beam switching). This self-service approach eliminates the need for continuous network scheduling and reduces energy consumption by performing measurements only when the UE itself determines it is necessary.

Inventive Principle:

Principle #25Self-service

3Measurement precision

If multiple beam measurements are performed for each reporting, then reporting accuracy is improved, but transmission overhead increases

Engineering Contradiction:

Improvereporting accuracyVSAvoidtransmission overhead

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent extracts and reports only the essential beam measurement information triggered by specific events, rather than reporting all measured beam parameters continuously. By taking out only the necessary measurement data related to event triggers (beam failure, handover, switching), the system maintains reporting accuracy while significantly reducing transmission overhead.

Inventive Principle:

Principle #2Taking out (Extraction)

4Quantity of substance

If UE grouping and coordination is used for beam reporting, then overhead is reduced, but transmission overhead from frequent measurements remains high

Engineering Contradiction:

Improvetransmission overheadVSAvoidenergy consumption from measurements

Core Design Contradiction:

Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

The event-triggered mechanism replaces periodic beam measurements with event-driven measurements. UEs in groups perform measurements and send reports only when specific events occur, rather than continuously. This eliminates the energy consumption associated with frequent periodic measurements while still reducing overall transmission overhead through coordinated group reporting.

Inventive Principle:

Principle #19Periodic action

AI summary

Aspects of the present disclosure provide methods, apparatuses and devices for event-triggered operation in beam-based communications. A device may transmit, to an apparatus, event triggering information indicative of one or more conditions that when satisfied trigger the apparatus to perform a certain action such as beam measurement and/or beam measurement reporting. The event triggering information may be configured by the device and specific to the apparatus. The apparatus may obtain sensing information related to the event triggering information and/or beam measurement information related to the event triggering information. The apparatus may determine whether the one or more conditions are satisfied based on the event triggering information and/or the sensing information. The apparatus may perform the action when the one or more conditions are satisfied.
