Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient methods for terminals to perform accurate cell reselection based on wireless charging capabilities supported by neighboring cells, leading to suboptimal charging solutions.
Innovation Solution
Implementing methods and apparatuses for cell capability indication and reselection that allow base stations to send and terminals to receive information about neighboring cells' wireless charging capabilities, using various signaling types such as broadcast, unicast, and on-demand system information, enabling terminals to prioritize and select cells based on charging capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If terminals perform cell reselection without capability information, then cell selection is simple, but wireless charging energy transfer efficiency deteriorates
Solution Approach 1:
The base station performs preliminary action by sending capability information of neighboring cells to the terminal in advance through system information broadcasting or dedicated signaling. This allows the terminal to perform informed cell reselection based on wireless charging capabilities without requiring complex real-time measurements, thus maintaining fast reselection speed while improving energy transfer efficiency.
2Measurement precision
If base station sends capability information of all neighboring cells, then terminal can accurately select cells with wireless charging capabilities, but signaling overhead increases
Solution Approach 1:
The base station applies local quality by selectively sending capability information only for neighboring cells that support wireless charging functions, rather than broadcasting information for all neighboring cells. This targeted approach allows terminals to accurately identify suitable cells for wireless charging while minimizing unnecessary signaling overhead for cells that cannot provide the required service.
3Loss of energy
If terminals prioritize cells with strong wireless charging capabilities, then energy transfer efficiency improves, but network availability for non-charging services may deteriorate
Solution Approach 1:
The system implements dynamics by enabling terminals to dynamically adjust cell selection priorities based on their current service requirements. When wireless charging is needed, terminals prioritize cells with strong charging capabilities; when other services are needed, terminals can select from the full range of available cells. The base station provides comprehensive capability information that allows flexible, context-dependent cell selection rather than rigid prioritization.
