Pre-configured Measurement Gap Status Indication for UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular networks, there is a challenge in effectively managing pre-configured measurement gaps (MGs) for user equipment (UE), particularly in scenarios where the activation or deactivation of MGs is not consistently signaled, leading to potential errors in UE behavior and network performance.
Innovation Solution
The proposed solution involves defining specific trigger events for UE to check and update the status of pre-configured MGs, including BWP switching, activation/deactivation of secondary cells, and RRC reconfiguration, allowing the UE to autonomously identify and adjust MG status based on received messages or timer expiration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-configured measurement gaps are managed without specific trigger events, then the network configuration remains simple, but the UE behavior becomes inconsistent and error-prone
Solution Approach 1:
The patent applies preliminary action by pre-defining specific trigger events (BWP switching, SCell activation/deactivation, RRC reconfiguration) that automatically activate or deactivate pre-configured measurement gaps. This ensures the UE knows in advance when to check and update MG status, eliminating inconsistent behavior while maintaining manageable complexity through standardized triggers.
2Measurement precision
If the UE autonomously checks MG status frequently, then the MG status accuracy improves, but the signaling overhead and processing load increase
Solution Approach 1:
The patent implements periodic action by having the UE check MG status only at predetermined trigger events rather than continuously or autonomously at arbitrary intervals. The trigger events (BWP switching, SCell activation/deactivation, RRC reconfiguration) create a structured periodic checking mechanism that ensures accurate MG status determination while minimizing unnecessary signaling overhead and processing load.

AI summary
Various embodiments herein provide techniques related to a user equipment (UE). In embodiments, the UE may identify occurrence of a triggering event related to a configured preconfigured measurement gap (pre-MG). Further, the UE may check, based on occurrence of the triggering event, a status of the configured pre-MG. Further, the UE may change, based on the occurrence of the triggering event, the status of the configured pre-MG. Other embodiments may be described and/or claimed.
