Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conflict between sensing windows and sleep windows in sidelink communication systems leads to uncertainty in terminal operations, resulting in potential power consumption inefficiencies and disrupted data services.
Innovation Solution
A conflict resolution policy is configured through first configuration information, indicating how to handle overlapping sensing and sleep windows, allowing terminals to perform sensing operations or enter sleep states appropriately, thereby ensuring smooth data service implementation while reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the sensing window and sleep window are separately configured, then the terminal can perform sensing operations and reduce power consumption, but the configured sensing window may conflict with the configured sleep window, causing the terminal to be uncertain whether to perform sensing or enter sleep state
Solution Approach 1:
The patent applies parameter changes by modifying the configuration parameters of the sensing window and sleep window. Specifically, it adjusts the time domain parameters (start position, length) of these windows to eliminate their overlap. The network device configures the sensing window parameters and sleep window parameters separately, then optimizes them to ensure they do not conflict, thereby maintaining both power saving and operational certainty.
2Use of energy by moving object
If the terminal enters sleep state in the sleep window, then power consumption is reduced, but the terminal cannot perform sensing operations, which may disrupt data services
Solution Approach 1:
The patent applies segmentation by dividing the time resource into distinct sensing window and sleep window segments that do not overlap. The sensing window is allocated for sensing operations to ensure data service continuity, while the sleep window is allocated for power saving. By segmenting these functions into non-overlapping time periods, the system resolves the conflict between power consumption and service continuity.
3Reliability
If the terminal performs sensing operation in the sensing window, then available sidelink resources are determined, but the configured sensing window may overlap with the sleep window, causing uncertainty in terminal operations
Solution Approach 1:
The patent applies feedback by implementing a configuration mechanism where the network device provides feedback information to the terminal regarding the sensing window and sleep window parameters. The network device monitors the terminal's sensing operations and adjusts the window configurations accordingly to eliminate overlaps. This feedback loop ensures sensing operation reliability while managing configuration complexity through centralized control.

AI summary
An information configuration method includes generating first configuration information, where the first configuration information indicates a conflict resolution policy used when a sleep window conflicts with a sensing window, where the sleep window is a time resource in which a sleep state is to be entered, and the sensing window is a time resource in which a sensing operation is to be performed; and transmitting the first configuration information to configure the conflict resolution policy to be used when the sleep window conflicts with the sensing window such that a device receiving the first configuration information be able to execute the corresponding conflict resolution policy used when the sleep window conflicts with the sensing window.
