Downlink Data Size Measurement for MT-EDT
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining when to use mobile terminating early data transmission (MT-EDT) in wireless communication systems are inefficient, often requiring unnecessary resource allocation and failing to selectively apply MT-EDT only to devices configured for single packet transmissions.
Innovation Solution
The proposed solution involves sending a downlink data size measurement indication to determine whether to measure the size of downlink data for an MT-EDT procedure, allowing for selective application of MT-EDT based on subscription parameters and traffic profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If downlink data size measurement is performed for all MT-EDT procedures, then measurement precision is improved, but device complexity and resource consumption increase
Solution Approach 1:
The patent applies local quality by making the measurement configuration selective rather than universal. The network node configures downlink data size measurement only for specific UEs based on their subscription parameters and traffic profiles, rather than applying it to all UEs. This targeted approach maintains measurement precision where needed while reducing overall system complexity and resource consumption.
Solution Approach 2:
The patent uses parameter changes by modifying the measurement configuration parameters based on UE-specific attributes. The network node evaluates subscription parameters and traffic profiles to dynamically adjust whether measurement is enabled for each UE. This allows the system to adapt measurement behavior to match actual service requirements, avoiding unnecessary measurements and reducing complexity.
2Productivity
If MT-EDT is applied to all devices, then productivity is improved, but loss of energy increases due to unnecessary resource allocation
Solution Approach 1:
The patent applies partial action by implementing selective MT-EDT application rather than universal application. The network node enables MT-EDT only for UEs whose subscription parameters and traffic profiles indicate suitability for single-packet transmission optimization. This partial application maintains high productivity for eligible devices while avoiding energy waste from applying MT-EDT to devices that don't benefit from it.
3Reliability
If downlink data size measurement is always performed, then reliability is improved, but loss of time increases due to unnecessary measurements and signaling
Solution Approach 1:
The patent applies preliminary action by pre-evaluating UE suitability for MT-EDT based on subscription parameters and traffic profiles before actual data transmission. The network node configures measurement capability in advance for eligible UEs, so that when downlink data arrives, the decision to use MT-EDT can be made quickly without performing full measurements or extensive signaling at transmission time. This maintains reliability for configured UEs while reducing time loss.

AI summary
Apparatuses and methods for configuration of downlink data measurement at mobile terminating early data transmission (MT-EDT) are provided. In one embodiment, a method implemented at a network node includes determining whether to measure a size of downlink data for a mobile terminating early data transmission, MT-EDT, procedure associated with a user equipment, UE; as a result of the determination, obtaining a measurement of the size of the downlink data; and optionally, sending the measurement of the size of the downlink data to a second network node.
