Target Cell Measurement Reporting for Timely Beam Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio resource management in wireless communication systems fails to perform beam management in a timely manner during cell changes, leading to cell performance loss.
Innovation Solution
A terminal performs measurements on a target cell based on a first configuration and reports the measurement result when a first event is satisfied, where the event includes receiving first signaling and ensuring the target cell's signal quality meets a condition within a specified duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the terminal performs L3 measurement and reports measurement result to base station, then the base station can accomplish cell change, but beam management cannot be performed in a timely manner leading to cell performance loss
Solution Approach 1:
The patent applies preliminary action by having the terminal perform L1 measurement in advance before cell change is completed. The terminal measures L1 parameters (such as reference signal received power) on the target cell beforehand and reports these pre-measured results to the base station, enabling the base station to configure beam management parameters before the actual handover occurs. This eliminates the delay in beam management that would otherwise wait for post-cell-change measurement results.
2Stability of the object's composition
If the terminal waits for cell change to complete before performing beam management, then cell change can be stabilized, but beam management is delayed causing performance loss
Solution Approach 1:
The terminal performs L1 measurement on the target cell before completing the cell change process. By measuring and reporting beam-related parameters (such as reference signal received power) in advance, the system enables beam management configuration to occur before handover completion, thus maintaining both cell change stability and beam management efficiency without requiring sequential completion of both processes.
Solution Approach 2:
The patent implements feedback by having the terminal report L1 measurement results back to the base station before cell change is finalized. The base station receives this feedback information (measurement results including beam parameters) and uses it to configure appropriate beam management settings for the upcoming cell change, ensuring that beam alignment is established proactively rather than reactively after the handover occurs.
