Communication Processor Delay Measurement for 5G QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, electronic devices may not measure and report delay times for data transmission when configuration information lacks an indicator, leading to difficulties for base stations in allocating sufficient uplink grants, resulting in deteriorated quality of service due to insufficient resource allocation.
Innovation Solution
An electronic device with a communication processor that identifies and measures delay times for specific services, even without explicit configuration, and transmits a measurement report including the average delay time and DRB information to the base station, enabling increased uplink grants and improved quality of service.

Engineering Contradiction Analysis
1Device complexity
If the electronic device does not transmit measurement report including delay time when configuration information lacks indicator, then device complexity is reduced, but quality of service deteriorates due to insufficient uplink grant allocation
Solution Approach 1:
The electronic device autonomously determines whether to perform delay time measurement and reporting based on service requirements and delay time conditions, without requiring explicit base station configuration. The device self-manages the measurement reporting process by comparing measured delay times against threshold values and autonomously initiating reports when conditions are met, thereby improving QoS while maintaining operational simplicity.
2Reliability
If the electronic device autonomously measures and reports delay time without configuration, then quality of service improves through better resource allocation, but device complexity increases due to additional measurement and reporting functions
Solution Approach 1:
The electronic device changes the parameter of delay time measurement based on service requirements and compares it against threshold values. The device dynamically adjusts whether to perform measurement and reporting by evaluating service types (e.g., eMBB, URLLC, mMTC) and their associated delay time thresholds, thereby improving QoS through targeted measurements rather than continuous reporting, which reduces overall complexity.
Solution Approach 2:
The electronic device performs delay time measurement and reporting only when necessary - specifically when service requirements indicate delay sensitivity and when measured delay times exceed configured thresholds. Rather than continuously measuring and reporting all delay times, the device applies partial action by selectively reporting only when QoS degradation is detected or prevention is needed, thus improving effectiveness while minimizing complexity.
3Productivity
If the base station allocates small uplink grant size for maintaining QoS, then resource efficiency is improved, but delay time increases leading to QoS deterioration
Solution Approach 1:
The electronic device provides feedback to the base station by transmitting measurement reports containing delay time information when delay thresholds are exceeded. This feedback mechanism enables the base station to adjust uplink grant allocations dynamically - maintaining small grant sizes for efficiency when delay conditions are met, while increasing grants when delay time feedback indicates QoS degradation risk, thereby resolving the contradiction between resource efficiency and delay time.

AI summary
The electronic device includes: a communication circuit for transmitting or receiving data to or from a network through cellular communication; an application processor; and a communication processor to: receive, from the application processor, information about one specified application and a first delay time for the specified application to perform one specified service; determine whether to identify an average of delay times while transmitting data related to the specified service, based on comparing a delay time occurring while transmitting the data related to the specified service through at least one data radio bearer (DRB) with a first time determined based on the first delay time; identify the average of the delay times on the basis of determining to identify the average; and determine whether to transmit a measurement report including the average of the delay times and information about the DRB, based on whether the average satisfies a specified condition.
