Power Saving Channel Switching With Preconfigured Wake-Up Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication protocols face inefficiencies due to the additional resource consumption required for switching between power saving and active modes, leading to system inefficiencies.
Innovation Solution
A first communication device switches between power saving and active states based on data service and traffic, receiving power saving configurations from a second device and using wake-up indications via a power saving channel to improve resource utilization.

Engineering Contradiction Analysis
1Use of energy by moving object
If a device switches between power saving mode and active mode for different types of services, then power consumption is optimized, but additional resources (frequency resources, time resources, energy resources) are consumed during mode switching
Solution Approach 1:
The system pre-configures multiple power saving configurations with different parameters (monitoring occasions, wake-up indications, channel configurations) before mode switching is needed. When a mode switch is required, the device can quickly activate a pre-configured power saving configuration without performing complex real-time negotiations, thereby reducing the resources consumed during the actual switching process while still achieving power consumption optimization.
2Use of energy by moving object
If a device frequently switches between active state and power saving states based on data service and traffic, then power efficiency is improved, but system resource utilization may deteriorate due to switching overhead
Solution Approach 1:
The system implements dynamic power saving configurations that can be adjusted based on current data service requirements and traffic patterns. Multiple configurations with different monitoring occasions and wake-up indication parameters are maintained, allowing the device to dynamically select the most appropriate configuration for current conditions. This dynamic approach enables frequent power state transitions when needed while optimizing system resource utilization by adapting to actual traffic demands rather than using fixed switching patterns.
