Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in efficiently managing energy consumption at network side devices, such as base stations, by transitioning to energy-saving states while maintaining effective synchronization and communication capabilities.
Innovation Solution
Implementing a wake-up signal (WUS) configuration mechanism that allows terminals to determine and send a wake-up signal to network side devices in energy-saving states, enabling them to transition back to a non-energy-saving state for normal operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the network side device switches to an energy saving state and sends only special synchronization signal blocks, then energy consumption is reduced, but communication and synchronization capabilities are compromised
Solution Approach 1:
The terminal performs preliminary actions by detecting whether the network side device is in an energy saving state before initiating random access. The terminal obtains wake-up signal configuration information and sends wake-up signals to the network side device in advance, ensuring the network device is awake and ready to receive the random access signal before the terminal actually needs to communicate.
Solution Approach 2:
The system implements feedback mechanisms where the terminal receives first information from the network side device to determine wake-up signal configuration. The terminal sends wake-up signals based on this feedback information, and the network side device switches from energy saving state to non-energy saving state in response, creating a closed-loop feedback system that balances energy saving with communication reliability.
2Loss of time
If the terminal sends wake-up signals to network side devices in energy saving state, then network device wake-up timing is improved, but additional signaling overhead is introduced
Solution Approach 1:
The system employs periodic action through the use of periodic wake-up signals and periodic transmission of first information from the network side device. The terminal sends wake-up signals at predetermined intervals or based on periodic configurations, and the network side device periodically transmits first information containing wake-up signal configuration. This periodic mechanism reduces the need for continuous signaling while ensuring timely wake-up.
Solution Approach 2:
The terminal performs self-service by autonomously determining whether the network side device is in an energy saving state and automatically sending wake-up signals without requiring constant network intervention. The terminal uses the first information it receives to independently configure and send appropriate wake-up signals, reducing the overall signaling overhead by eliminating unnecessary network-side configuration messages.
