Cell Status Reporting via Bitmap for UE Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, such as LTE, lack an efficient method for reporting cell activation status information, which is essential for optimizing resource allocation and battery life in user equipment (UE), particularly in scenarios involving multiple cells with varying activation states.
Innovation Solution
A method for reporting cell activation status information at the UE, where the UE periodically or upon specific conditions (like activation or deactivation commands) transmits bitmap information indicating the activation status of multiple cells, allowing the network to manage resource allocation and power consumption effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continuously monitors and reports cell status information for multiple cells, then the network can optimize resource allocation and power management, but the UE's power consumption increases and reporting efficiency decreases
Solution Approach 1:
The patent implements periodic cell status reporting where the UE reports cell activation status information at predetermined intervals or upon specific triggering events (such as cell activation/deactivation). This periodic reporting mechanism reduces continuous monitoring requirements while ensuring the network receives timely status updates for resource allocation and power management optimization.
2Loss of information
If the UE reports detailed activation status information for all configured cells, then the network gains comprehensive resource management capability, but the signaling overhead and reporting complexity increase
Solution Approach 1:
The patent extracts and reports only the essential cell status information (activation/deactivation state) rather than comprehensive cell parameters. By focusing on the most critical status indicators that directly impact resource allocation and power management, the reporting mechanism achieves effective network control while minimizing signaling overhead and processing complexity.

AI summary
A method for reporting cell activation status information at a user equipment (UE) in a wireless communication system is disclosed. The method includes a step of reporting, to a network, the cell activation status information for a plurality of cells configured to the UE when a condition is met, wherein the cell activation status information for the plurality of cells indicates whether each of the plurality of cells is activated or deactivated.
