Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in efficiently reporting measurement results of queuing delay and service quality in uplink data packets, leading to suboptimal resource allocation and interference management.
Innovation Solution
A user terminal equipped with a receiver, controller, and transmitter is configured to receive configuration information for measuring queuing delay, perform measurements, and report results to a radio base station only when thresholds are exceeded, enabling appropriate scheduling and interference management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement results are reported continuously per unit time, then the radio base station can obtain comprehensive measurement data for resource allocation, but the user terminal experiences increased processing load and signaling overhead
Solution Approach 1:
The patent extracts only the essential measurement information (queuing delay values exceeding threshold) from the complete measurement data set, transmitting only when necessary conditions are met. This selective extraction reduces the volume of reported data while maintaining the reliability needed for effective resource allocation and interference management.
Solution Approach 2:
The patent introduces a threshold parameter for queuing delay measurement results, changing the reporting condition from continuous to event-driven based on parameter comparison. This parameter-based filtering mechanism reduces signaling overhead and processing load while ensuring that only significant measurement data is reported to the radio base station.
2Loss of information
If all measurement results are reported, then complete information is available for network optimization, but signaling overhead and network traffic increase
Solution Approach 1:
The patent extracts only the essential measurement information (queuing delay values exceeding threshold) from the complete measurement data set, transmitting only when necessary conditions are met. This selective extraction reduces the volume of reported data while maintaining the reliability needed for effective resource allocation and interference management.
Solution Approach 2:
Instead of reporting all measurement results (excessive action), the patent reports only those measurements that exceed the configured threshold (partial action). This partial reporting approach maintains sufficient information for network optimization while significantly reducing signaling overhead and energy consumption.
3Speed
If measurement reporting is performed frequently, then timely resource allocation decisions can be made, but the user terminal consumes more energy and processing resources
Solution Approach 1:
The patent implements periodic measurement with event-triggered reporting, where measurements are performed at regular intervals but reported only when queuing delay exceeds the threshold. This periodic measurement approach ensures timely detection of resource allocation issues while reducing energy consumption by avoiding continuous reporting of normal conditions.
Solution Approach 2:
The patent establishes a feedback mechanism where the user terminal monitors queuing delay and provides selective feedback to the radio base station only when threshold violations occur. This feedback-based approach enables timely resource allocation decisions while minimizing energy consumption by avoiding unnecessary reporting during normal operating conditions.

AI summary
A user terminal comprises a receiver configured to receive, configuration information configuring measurement for a queuing delay of data packet in an uplink, from a radio base station in a dedicated manner; a controller configured to perform the measurement; and a transmitter configured to report a result of the measurement to the radio base station per unit time. The configuration information includes information indicating length of the unit time and threshold information indicating a threshold related to the queuing delay. The controller is configured to perform the measurement per unit time. The transmitter is configured to report the result of the measurement upon measuring the queuing delay exceeding the threshold within the unit time. The transmitter is configured to not report the result of the measurement upon measuring the queuing delay not exceeding the threshold within the unit time.
