Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sidelink synchronization procedure is continuously enabled for UE, then communication reliability is improved, but communication flexibility and efficiency deteriorate
Solution Approach 1:
The patent implements dynamic control of sidelink synchronization procedures by enabling the network to trigger enabling or disabling of synchronization based on current communication conditions. The UE transitions between synchronized and unsynchronized states dynamically, allowing the system to adapt synchronization behavior to actual needs rather than maintaining a fixed state.
Solution Approach 2:
The patent changes the synchronization state parameter of the UE based on network indications. The network can trigger a parameter change that switches the sidelink synchronization procedure from enabled to disabled state, or vice versa, allowing flexible control over synchronization behavior to optimize communication efficiency.
2Stability of the object's composition
If sidelink synchronization procedure is enabled for all UEs, then communication stability is improved, but system resource consumption increases
Solution Approach 1:
The patent applies local quality by enabling sidelink synchronization procedures selectively for specific UEs based on their individual communication needs and conditions, rather than uniformly for all UEs. The network can trigger synchronization enabling or disabling for particular UEs, optimizing resource consumption while maintaining stability where required.
3Productivity
If sidelink synchronization is dynamically controlled, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The patent introduces the network as an intermediary that manages the complexity of dynamic synchronization control. Rather than requiring complex UE-side decision-making, the network sends indications to trigger synchronization enabling or disabling, simplifying the UE implementation while achieving dynamic control for improved communication efficiency.

AI summary
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for communications based on sidelink synchronization. A UE may receive an indication associated with enabling or disabling a sidelink synchronization procedure of the UE, where the sidelink synchronization procedure of the UE may be enabled or disabled based on the indication. The UE may communicate with a wireless device via a sidelink communication based on whether the sidelink synchronization procedure of the UE is enabled or disabled.
