Solution Overview
Problem
Current wireless communication systems face inefficiencies in energy harvesting for user equipment, particularly when user equipment needs to access base stations that are far away, leading to lower energy harvesting efficiency due to traditional access strategies that prioritize signal-to-interference and noise ratio over energy transmission efficiency.
Innovation Solution
The system configures an electronic device with processing circuitry to control user equipment to receive wireless signals from base stations and convert them into electromagnetic energy for harvesting, using specific frame structures and cooperative base stations to optimize energy harvesting without interfering with data transmission, and allows user equipment to switch between data transmission and energy harvesting modes based on power thresholds and base station coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment accesses distant base stations using traditional signal-to-interference ratio optimization, then connection reliability is improved, but energy harvesting efficiency deteriorates
Solution Approach 1:
The system dynamically switches between data transmission mode and energy harvesting mode based on real-time conditions. User equipment can adaptively adjust its operation mode to optimize either connection reliability or energy harvesting efficiency depending on the current scenario, resolving the contradiction between these two objectives.
Solution Approach 2:
The patent segments the operation into distinct modes: data transmission mode for maintaining connection reliability and energy harvesting mode for maximizing energy collection. By separating these functions into different operational segments, the system can optimize each independently without compromise.
2Productivity
If frame structures are optimized for data transmission, then data transmission efficiency is improved, but energy harvesting performance deteriorates
Solution Approach 1:
The patent employs periodic frame structures with alternating data transmission slots and energy harvesting slots. This periodic arrangement allows the system to maintain regular data transmission schedules while periodically dedicating resources to energy harvesting, balancing both objectives through time-division multiplexing.
Solution Approach 2:
The frame structure is dynamically configurable to adjust the proportion of data transmission resources versus energy harvesting resources based on current system demands. This dynamic adjustment allows optimization of data transmission efficiency when needed while preserving capability for energy harvesting performance improvement.
3Loss of energy
If user equipment continuously harvests energy from wireless signals, then energy harvesting efficiency is improved, but data transmission quality deteriorates
Solution Approach 1:
The patent segments operational time into distinct data transmission periods and energy harvesting periods. During data transmission periods, the full signal power is allocated to maintaining high-quality communication. During energy harvesting periods, the same resources are dedicated to energy collection, ensuring neither function compromises the other.
Solution Approach 2:
The system implements periodic switching between data transmission and energy harvesting operations. This periodic action ensures that data transmission quality is maintained during communication slots while energy harvesting efficiency is maximized during dedicated harvesting slots, preventing mutual interference.
