Solution Overview
Problem
Current radio measurement principles in wireless communication systems lack flexibility, as they are bound to their specific purposes and do not allow for dynamic control of data collection.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radio measurements are always bound to their specific purpose (immediate CSI-reports or logged MDT), then the measurement framework is simple and well-defined, but the system lacks flexibility in data collection control
Solution Approach 1:
The patent creates a universal measurement framework where a single measurement configuration can serve multiple purposes. The network can activate the same measured components for different functions (immediate reporting, logged MDT, or flexible data collection) based on current needs, eliminating the need for separate dedicated configurations for each measurement type.
Solution Approach 2:
The patent introduces dynamic activation and deactivation of measurement components through MAC control elements. The network can flexibly control when measurements are performed and how results are reported, transitioning between different operational modes (immediate, logged, or flexible collection) without reconfiguring the entire measurement framework.
2Reliability
If immediate CSI-reports are transmitted at every reporting instance, then the network receives up-to-date channel information, but the signaling overhead and network resource usage increase
Solution Approach 1:
The patent implements periodic reporting where measurements are performed continuously but results are transmitted only at configured reporting instances or when activation commands are received. This reduces signaling overhead while maintaining the ability to provide timely channel status information when needed.
Solution Approach 2:
The network receives measurement results and can send activation/deactivation commands based on current needs. This feedback mechanism allows the system to adjust reporting behavior dynamically, reducing overhead when immediate updates are not required while maintaining reliability when channel conditions change.
3Productivity
If logged MDT is used for UEs in idle state, then the network can collect measurement data without additional signaling, but the data collection is limited to idle state UEs and lacks real-time control
Solution Approach 1:
The patent enables UEs to perform measurements and store results locally without continuous network signaling, similar to logged MDT. However, the network retains control by sending activation commands that trigger reporting, combining the efficiency of autonomous measurement with the control flexibility of network-managed reporting.
Solution Approach 2:
The network pre-configures measurement parameters and reporting conditions, then activates data collection when needed. Measurements are performed and stored in advance, with reporting triggered by network commands or configured events, allowing efficient data collection with maintained control flexibility.

AI summary
Methods, apparatuses, and systems are provided for radio measurements in mobile communications. A user equipment in radio resource control connected state may according to the presented solution receive, from a network node, a logged radio measurement report configuration indicating one or more logged radio measurement conditions, and perform logged radio measurements over time according to the one or more logged radio measurement conditions. Similarly, a network node may determine that data collection of logged radio measurements in radio resource control connected state is to be initiated with a user equipment in connected state, and transmit, to the user equipment, a logged radio measurement report configuration indicating one or more logged radio measurement conditions.
