Sidelink Power Control Mode Switching via Network State Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems do not effectively account for network operation states in sidelink power control, leading to inefficiencies in power usage and interference, as sidelink power control operations are often performed independently of network states.
Innovation Solution
A user equipment (UE) receives control signaling indicating the correspondence between network operation states and sidelink power control modes, allowing it to switch between modes based on changes in network operation states, thereby adapting sidelink power control parameters to optimize communication quality and reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sidelink power control operations are performed independently of network states, then power control simplicity is maintained, but power usage efficiency and interference management deteriorate
Solution Approach 1:
The patent applies dynamics by making the sidelink power control mode changeable based on network operation states. The UE dynamically switches between different power control modes (e.g., first power control mode and second power control mode) corresponding to different network states (e.g., first network operation state and second network operation state), allowing the system to adapt power control behavior to current network conditions and improve power usage efficiency.
Solution Approach 2:
The patent changes the parameter of power control mode based on network operation states. By establishing correspondences between network operation states and sidelink power control modes, the system adjusts power control parameters dynamically to match network conditions, thereby improving energy efficiency while maintaining manageable complexity through predefined correspondence relationships.
2Device complexity
If sidelink power control is independent of network operation states, then implementation simplicity is maintained, but interference management deteriorates
Solution Approach 1:
The system dynamically adjusts sidelink power control modes based on real-time network operation states. When the network transitions between different operation states, the UE automatically switches to the corresponding power control mode, enabling adaptive interference management without requiring complex manual configuration or independent implementation.
Solution Approach 2:
The patent implements feedback mechanisms where the UE monitors network operation states and adjusts power control modes accordingly. This feedback loop ensures that power control actions are coordinated with network conditions, effectively managing interference while maintaining implementation simplicity through automated state-responsive control.
3Stability of the object's composition
If fixed power control modes are used regardless of network state changes, then system stability is maintained, but communication quality and reliability deteriorate
Solution Approach 1:
The system transitions from fixed to dynamic power control modes based on network operation states. The UE establishes correspondences between network states and power control modes, switching automatically when network states change. This dynamic adaptation improves communication quality and reliability by ensuring power control parameters are optimized for current network conditions while maintaining stability through structured correspondence relationships.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, over an access link, first control signaling indicating a correspondence between network operation states of a network and sidelink power control modes of the UE for sidelink communications. The UE may switch from a first sidelink power control mode to a second sidelink power control mode based on a change in a network operation state by the first network entity from a first network operation state to a second network operation state, where the second sidelink power control mode may correspond to the second network operation state. The UE may communicate one or more sidelink messages with the second wireless device, a programmable logic controller, or both over a sidelink channel in accordance with the second sidelink power control mode.
