UE Multi-Radio Connectivity Control for Battery-Aware Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power management systems in multi-radio connectivity scenarios, such as EN-DC, fail to efficiently reduce power consumption in user equipment (UE) when battery state, voltage, or temperature thresholds are exceeded, leading to unnecessary resource utilization and increased power drain.
Innovation Solution
The UE enters a multi-radio connectivity mode, detects power-related conditions, and sends messages to the master node to release connections to secondary nodes, reducing power to components and muting or unmuting measurements as necessary to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE maintains connection to secondary nodes in multi-radio connectivity mode, then data throughput and resource availability are improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the connectivity configuration by transitioning between connected and idle states for secondary nodes based on real-time power conditions. When power thresholds are exceeded, the UE releases connections to secondary nodes; when thresholds are satisfied, connections are re-established. This dynamic state change allows the system to adapt power consumption levels while maintaining productivity when needed.
Solution Approach 2:
The invention changes the connectivity parameter (connection state to secondary nodes) in response to power parameter changes. By monitoring power-related conditions (battery state, voltage, temperature) and adjusting the connection status accordingly, the system optimizes the trade-off between data throughput and power consumption through parameter-based control.
2Duration of action of moving object
If the UE releases connection to secondary nodes to reduce power consumption, then battery life is extended, but data throughput and resource availability decrease
Solution Approach 1:
The system implements periodic monitoring of power-related conditions and periodic re-evaluation of connection states. The UE continuously monitors power parameters and periodically adjusts connectivity configuration based on current conditions, allowing it to extend battery life during low-power periods while restoring throughput capability when power conditions improve.
3Use of energy by moving object
If the UE continuously monitors power-related conditions and dynamically adjusts connectivity, then power consumption is optimized, but device complexity increases
Solution Approach 1:
The system implements a feedback mechanism where the UE monitors power-related conditions (battery state, voltage, temperature) and uses this feedback to dynamically adjust connectivity configuration. The master node receives indications from the UE about power conditions and accordingly adjusts the connection state to secondary nodes, creating a closed-loop control system that optimizes power consumption through condition-based feedback.

AI summary
A UE may, responsive to detecting a power-related condition, send a message to induce the master node to release the secondary node. Such a message can include a message reporting a radio link failure of the secondary node, or, if a channel quality indicator is configured for at least some of the secondary cells of the secondary node, reporting a low CQI value so that the network can cease scheduling on such cells. Alternatively, in a carrier aggregation (CA) mode, with the UE connected to a single node comprising a primary cell and one or more secondary cells, the UE may not control which and how many secondary cells with which it communicates. In such a scenario, if such secondary cells are configured for channel quality indicator reporting, the UE may report a low CQI value so that the node will cease scheduling data on such cells.
