Communication Device Assistance for Idle-Mode Alternative Topology Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current procedures for logged UE measurements in wireless networks are inadequate for evaluating how network deployments would impact user equipment (UE) and network nodes if the network were deployed differently, and they do not support time-specific measurements.
Innovation Solution
Introduce new measurement configurations for idle mode logged measurements in wireless standards, enabling UEs to measure and report on specific broadcasted signals indicative of different operating modes, including separate measurements on SSBs, additional test reference signals, and uplink transmissions on non-camped cells, allowing networks to evaluate various configurations for energy savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current logged UE measurement procedures are used, then measurements can be performed while UE is in connected mode, but the network cannot evaluate alternative topology configurations or energy-saving deployment scenarios
Solution Approach 1:
The patent applies preliminary action by configuring UEs in advance with measurement parameters for alternative topology configurations before actually evaluating those configurations. The network provides configuration information including measurement objects, reporting configurations, and quantity configurations that prepare UEs to perform measurements on hypothetical alternative network deployments, enabling the network to gather UE experience data for configurations that may not be currently active.
2Productivity
If the network requires dense deployment to handle high load scenarios, then capacity is improved, but energy consumption increases during low load scenarios
Solution Approach 1:
The patent applies dynamics by enabling the network to dynamically evaluate and switch between different topology configurations based on load conditions. The measurement framework allows the network to assess alternative configurations (including energy-saving modes with fewer active nodes) and make informed decisions about when to activate or deactivate network nodes, transforming the static dense deployment into a dynamic system that adapts to varying traffic demands.
3Device complexity
If measurements are limited to UEs within current coverage, then measurement complexity is reduced, but the network cannot collect unbiased data on UE experiences across different configurations
Solution Approach 1:
The patent applies universality by designing a measurement framework that can handle multiple measurement objectives simultaneously. The same measurement configuration infrastructure supports both current topology evaluation and alternative topology assessment, connected mode measurements and idle mode measurements, thereby collecting comprehensive unbiased UE experience data without requiring separate specialized systems for each measurement type.

AI summary
A communication device in a communications network can receive configuration information from the network node using a first topology configuration while the communication device is in an active state. The configuration information can indicate a request for the communication device to perform an action associated with a second topology configuration that is different than the first topology configuration while the communication device is in an idle state. The communication device can transition to an idle state. The communication device can perform the action associated with the second topology configuration.
