Wireless Communication Measurement Logging via L2 Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G communication systems face challenges in accurately measuring and reporting network conditions when a User Equipment (UE) is not in an RRC connected state and connected via a L2 relay, leading to potential misjudgment or missed detection, especially in scenarios where the UE is out of coverage.
Innovation Solution
A method for UE to perform measurement result logging based on specific state conditions, including receiving a measurement configuration, performing operations via a relay, and determining whether to log measurements based on area configurations, even when not in an RRC connected state, with conditions for transitioning to a connected mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UE is not in an RRC connected state and connected via a L2 relay, then the UE can maintain network connectivity and access services, but measurement accuracy deteriorates leading to potential misjudgment or missed detection
Solution Approach 1:
The patent applies preliminary action by configuring the UE to perform measurements and log measurement results in advance while in RRC_IDLE or RRC_INACTIVE states via L2 relay. The measurement configuration is provided before the UE transitions to connected mode, enabling the UE to proactively collect measurement data (such as RSRP, RSRQ) during idle/inactive states. This preliminary measurement logging ensures that when the UE needs to report measurements or transition to connected mode, accurate and timely measurement data is already available, resolving the contradiction between maintaining connectivity in idle state and ensuring measurement accuracy.
2Measurement precision
If the UE performs comprehensive measurement logging in non-RRC connected state, then measurement accuracy improves, but device complexity increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting measurement parameters based on the UE's RRC state and relay connection status. The network configures specific measurement parameters (such as measurement objects, reporting configurations, and logging conditions) that are tailored to the UE's current state. When the UE is in RRC_IDLE or RRC_INACTIVE via L2 relay, the measurement configuration includes state-specific parameters that guide what to measure and how to log results. This parameter customization enables comprehensive measurement logging with improved accuracy while managing device complexity through standardized, state-aware configuration rather than universal complex measurement management.
