Multi-Carrier Power-Saving Information Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current communication systems, terminals configured with multiple carriers struggle to save energy due to semi-static configuration of carriers, separate power-saving information for each BWP, and lack of defined power-saving information for carriers with different subcarrier spacing, leading to increased power consumption.
Innovation Solution
Configuring a minimum value of power-saving information for all carriers, allowing terminals to perform resource scheduling based on this information, ensuring consistent power-saving across multiple carriers, and providing power-saving operations even when no data is scheduled or power-saving information is transmitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If separate power-saving information is configured for each BWP and carrier, then power-saving can be optimized for specific carriers, but terminal power consumption increases when working on multiple carriers
Solution Approach 1:
The patent combines power-saving information from multiple carriers into a unified indication mechanism. The terminal determines a minimum value of power-saving information across all configured carriers and applies this unified value to all carriers, reducing the need for separate preparations on each carrier while maintaining power-saving effectiveness.
Solution Approach 2:
The patent creates a universal power-saving indication that can be applied across multiple carriers with different subcarrier spacings. By determining a minimum power-saving value that works across all carriers, the system achieves multi-functionality where a single indication serves multiple carriers simultaneously, reducing terminal complexity.
2Adaptability or versatility
If cross-carrier scheduling is implemented with different subcarrier spacing, then scheduling flexibility improves, but power-saving configuration becomes undefined
Solution Approach 1:
The patent changes the parameter basis for power-saving indication from carrier-specific configurations to a unified minimum value across carriers. This allows the system to maintain scheduling flexibility with different subcarrier spacings while defining a clear power-saving configuration method that works across all carriers regardless of their specific parameters.
3Reliability
If terminal prepares for data transmission on all configured carriers, then data transmission readiness is ensured, but energy consumption increases
Solution Approach 1:
The patent applies partial action by having the terminal prepare only to the extent necessary based on the minimum power-saving value determined across all carriers. Instead of full preparation on all carriers simultaneously, the terminal performs selective preparation based on the unified power-saving indication, reducing energy consumption while maintaining necessary transmission readiness.

AI summary
Embodiments of the present application provide a power-saving information transmission method, a base station, and a terminal. The method includes configuring, by a base station, first power-saving information of a first moment of a first carrier, the first power-saving information being used for indicating transmission of first information of the first carrier and/or a second carrier; and transmitting, by the base station, the first power-saving information. Embodiments of the present application can solve the problem that how to configure the power-saving information of multiple carriers in case that the base station is provided with multiple carriers and a terminal achieves a power-saving effect, and avoid or mitigate the problem that in case that different energy saving information are configured for different carriers, the terminal cannot save energy as long as the configuration for one carrier is not configured for energy saving, to reduce the power consumption of the terminal.
