Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the base station configures all power saving parameters for the terminal device, then the terminal device can achieve power saving optimization, but the signaling overhead increases significantly
Solution Approach 1:
The terminal device autonomously determines power saving parameter values based on pre-configured parameter sets and its own power saving mode, eliminating the need for the base station to explicitly configure each parameter. This self-service mechanism reduces signaling overhead while maintaining power saving optimization capabilities.
Solution Approach 2:
The patent uses parameter sets that define multiple power saving parameters together, where changing one parameter (power saving mode) automatically triggers changes to multiple related parameters. This parameter change approach allows comprehensive power saving configuration through minimal signaling.
2Productivity
If the base station configures all power saving parameters within a short time, then the configuration can be completed quickly, but the signaling overhead becomes excessively high
Solution Approach 1:
The patent merges multiple power saving parameters into parameter sets that are collectively configured based on the terminal device's power saving mode. Instead of configuring each parameter separately, the system combines related parameters into unified sets, achieving fast configuration with reduced signaling overhead.
Solution Approach 2:
The parameter sets serve multiple functions: they define power saving parameters, indicate configuration status, and enable the terminal device to autonomously determine appropriate values. This multi-functionality allows comprehensive configuration through minimal signaling, improving both speed and efficiency.
3Adaptability or versatility
If the terminal device reports power consumption information to the network-side device, then the network can optimize power saving configuration, but the signaling overhead increases
Solution Approach 1:
The terminal device reports power consumption information as feedback to the network-side device, which uses this feedback to optimize power saving configuration. The feedback mechanism enables adaptive optimization while maintaining efficient signaling by reporting only essential power consumption metrics rather than detailed parameter configurations.

AI summary
A configuration method and a device are provided. The method includes: sending a first message to a network-side device, where the first message explicitly or implicitly indicates a power saving mode or a power saving class of a terminal device; receiving, from the network-side device, first feedback information about the first message; and determining, based on the first feedback information, value(s) of one or more first parameters related to power consumption of the terminal device.
