Solution Overview

Problem

Current beam pair switching configurations in 5G wireless systems do not effectively manage interruptions during beam switching, leading to temporary degradation of UE throughput due to the network assuming worst-case scenarios without adequate reporting from the UE, resulting in missed scheduling opportunities.

Innovation Solution

The method involves the UE reporting the status of beam pair switching interruptions to the network, allowing for dynamic indications of whether specific beam pairs will cause interruptions, enabling the network to schedule radio transmissions accordingly and potentially select alternative beam pairs to avoid interruptions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the network assumes worst-case scenarios for beam pair switching interruptions, then reliability is improved, but productivity deteriorates due to missed scheduling opportunities

Engineering Contradiction:
Improvebeam switching reliabilityVSAvoidscheduling throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The UE provides feedback reports to the network indicating whether beam pair switching causes interruptions. The network uses this feedback to adjust scheduling decisions, avoiding missed opportunities while maintaining reliability where needed.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts scheduling behavior based on actual beam pair switching characteristics. Instead of static worst-case assumptions, the network adapts scheduling decisions to the specific interruption patterns reported by the UE for different beam pairs.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the network uses static worst-case scheduling assumptions, then reliability is improved, but adaptability deteriorates

Engineering Contradiction:
Improvescheduling reliabilityVSAvoidscheduling adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The scheduling system transitions from static worst-case assumptions to dynamic adaptation based on UE-reported beam pair characteristics. The network adjusts scheduling behavior in real-time according to the specific interruption patterns of different beam pairs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes scheduling parameters based on beam pair-specific interruption characteristics. Different beam pairs receive different scheduling treatments according to their reported interruption status, allowing optimized resource allocation.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the UE reports detailed beam pair interruption status, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvescheduling adaptabilityVSAvoidUE reporting complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The UE reports interruption status specifically for each beam pair rather than providing comprehensive device capabilities. This localized reporting focuses on the specific parameter needed for scheduling optimization without requiring full device complexity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system extracts only the essential interruption status information from the UE for each beam pair, rather than requiring comprehensive capability reporting. This minimal extraction provides sufficient data for adaptive scheduling while reducing reporting complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Systems, methods, apparatuses, and computer program products for low-power wake-up signal design. A method may include transmitting, to a network element, a report indicating status on whether at least one beam of at least one beam pair is interrupted or not when beam pair switching. The at least one beam pair may include at least a first beam associated with a first transmit and receive point, and a second beam associated with a second transmit and receive point. The method may also include receiving, in response to the report, scheduling for a radio transmission.
