Solution Overview
Problem
Existing wireless communication systems do not optimize the use of available energy for sensing and communicating operations, leading to inefficient performance in wireless communications networks, particularly in IoT devices where energy must be frugally managed for extended periods.
Innovation Solution
A method where a wireless device determines an optimal allocation of available energy between sensing and communicating operations based on control information and energy availability, using distinct configurations for each operation to maximize energy utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If energy is allocated to sensing operations, then sensing performance is improved, but energy for communicating operations is reduced
Solution Approach 1:
The patent implements dynamic energy allocation where the wireless device continuously monitors available energy and adjusts the split between sensing and communicating operations in real-time. The energy allocation is not fixed but adapts to current energy conditions, allowing the system to optimize performance based on varying energy availability while maintaining both sensing and communicating functions.
2Productivity
If energy is allocated to communicating operations, then communication performance is improved, but energy for sensing operations is reduced
Solution Approach 1:
The system dynamically adjusts energy allocation between communicating and sensing operations based on real-time energy availability. When energy is abundant, more can be allocated to communicating operations; when energy is constrained, the allocation shifts to preserve sensing capabilities, ensuring both functions can operate effectively under varying conditions.
3Device complexity
If fixed energy allocation is used, then device complexity is reduced, but adaptability to energy conditions is worsened
Solution Approach 1:
The wireless device autonomously monitors its own energy levels and automatically adjusts the energy allocation between sensing and communicating operations without external control. This self-service mechanism allows the device to adapt to changing energy conditions while keeping the control logic integrated within the device itself, balancing complexity and adaptability.

AI summary
A wireless device and a method therein for performing one or more operations based on available energy. The wireless device is configured to operate in a wireless communications network. Based on an amount of energy available for operation and based on control information, the wireless device determines an allocation of the amount of available energy between at least a first energy part and a second energy part. The first energy part is to be used in a sensing operation using a sensing operation configuration and the second energy part is to be used in a communicating operation using a communicating operation configuration. The wireless device performs based on the determined allocation, one or more operations out of: the sensing operation using the first energy part and the sensing operation configuration, and the communicating operation using the second energy part and the communicating operation configuration.
