1Productivity
If wireless charging capability information is transmitted through existing cellular network signaling protocols, then communication efficiency is improved, but the complexity of capability determination and configuration increases
Solution Approach 1:
The capability information transmission is segmented into distinct signaling messages: first capability information is sent from the base station to the core network device, and second capability information is sent from the core network device to the base station. This segmentation allows for organized and systematic capability determination while maintaining communication efficiency through standardized signaling protocols.
Solution Approach 2:
The base station performs preliminary action by determining its wireless charging capability and sending first capability information to the core network device before actual wireless charging operations begin. This preliminary capability declaration enables the core network device to configure appropriate parameters in advance, reducing operational complexity during actual charging.
2Manufacturing precision
If capability information is exchanged between base station and core network device, then wireless charging configuration accuracy is improved, but information transmission overhead increases
Solution Approach 1:
The patent extracts only the essential wireless charging capability information needed for configuration purposes. The first capability information contains base station wireless charging support status, and the second capability information contains core network device wireless charging support status. This extraction approach ensures configuration accuracy by including only necessary information while minimizing transmission overhead.
Solution Approach 2:
The capability information exchange mechanism is designed to be universal and multi-functional. The same signaling protocol framework can carry different types of capability information (base station capability, core network device capability) depending on the communication direction and context. This universality reduces overall information overhead by using a single standardized mechanism rather than multiple specialized protocols.

AI summary
A method for transmitting capability information, performed by a first base station, includes: sending first capability information for wireless charging to a core network device, the first capability information being configured to indicate whether the first base station supports a wireless charging capability. The first capability information may include support information, configured to indicate whether a base station supports wireless charging or not; power information, configured to indicate a power for wireless charging supported by the base station; or time information, configured to indicate a duration for wireless charging supported by the base station.
