UE Information Reporting for Beam Failure Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack a mechanism to effectively record and report abnormal events where a user equipment (UE) fails to use a dedicated resource for beam failure recovery or target cell random access but succeeds with a common resource, leading to unrecorded issues that can impact network optimization.
Innovation Solution
A method and device for information reporting that allow the UE to transmit information associated with both dedicated and common resources to the network device, enabling the recording of abnormal events where the UE fails to use a dedicated resource but succeeds with a common resource for beam failure recovery or target cell access, facilitating network reconfiguration to prevent such occurrences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE uses a dedicated resource for beam failure recovery or target cell random access, then the resource utilization efficiency is improved, but the reliability deteriorates when the dedicated resource fails and the UE must fall back to common resources
Solution Approach 1:
The patent implements a feedback mechanism where the UE reports abnormal events (failure on dedicated resource, success on common resource) to the network device. This feedback enables the network to identify configuration issues and optimize dedicated resource parameters, thereby improving reliability while maintaining efficient resource utilization.
Solution Approach 2:
The patent enables preliminary identification of abnormal events by recording and reporting them to the network device before they become persistent problems. This allows the network to perform preventive reconfiguration of dedicated resources, avoiding future failures and improving reliability proactively.
2Reliability
If the network device reconfigures dedicated resources based on abnormal event reports, then the reliability is improved, but the device complexity increases due to additional reporting and processing mechanisms
Solution Approach 1:
The patent extracts only the essential abnormal event information (dedicated resource failure, common resource success) for reporting, rather than transmitting complete detailed logs. This selective extraction reduces reporting overhead and processing complexity while still providing sufficient information for network optimization.
Solution Approach 2:
The patent utilizes existing uplink communication channels and message structures for abnormal event reporting, rather than creating entirely new dedicated reporting mechanisms. This multi-functional use of existing infrastructure minimizes additional device complexity while enabling reliable abnormal event detection and reporting.

AI summary
A method for information reporting, a UE, and a network device are provided. The method includes the following. A UE transmits first information to a network device, where the first information includes at least one of: information associated with a first dedicated resource, or information associated with a first common resource. The first dedicated resource is a dedicated resource with which the UE executes a first event, and the first common resource is a common resource with which the UE executes the first event, the first event includes one of: a target cell access event during handover and a beam failure recovery event.
