Beam Pair Switching Interruption Reporting in 5G Networks
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Reliability
If the network uses static worst-case scheduling assumptions, then reliability is improved, but adaptability deteriorates
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.
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.
3Adaptability or versatility
If the UE reports detailed beam pair interruption status, then adaptability is improved, but device complexity increases
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.
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.

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.
