Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional one-to-many terminal synchronization method is used, then synchronization can be achieved, but device complexity and cost increase due to requiring random access and Time Advance technologies
Solution Approach 1:
The patent extracts and removes the complex random access and Time Advance procedures from the synchronization process. Instead, it directly transmits synchronization signals (SS) and state information between terminals, achieving synchronization without these intermediate complex technologies, thus reducing device complexity while maintaining synchronization reliability
Solution Approach 2:
The patent inverts the traditional synchronization architecture by enabling terminals to directly synchronize with each other without requiring base station coordination for random access and Time Advance. Terminals autonomously exchange synchronization information and adjust their timing based on received state information, reversing the dependency relationship and eliminating complex control procedures
2Reliability
If traditional one-to-many terminal synchronization method is used, then synchronization can be achieved, but cost increases due to complex technologies and processes
Solution Approach 1:
The patent removes the need for expensive base station coordination infrastructure and complex signal processing algorithms associated with random access and Time Advance. By enabling direct terminal-to-terminal synchronization through simple SS and state information exchange, it significantly reduces implementation cost while maintaining synchronization reliability
Solution Approach 2:
The patent uses lightweight, simple synchronization messages (SS and state information) that can be quickly generated and processed by terminals without requiring expensive hardware or complex software implementations. These simple information elements replace costly complex procedures, achieving the same synchronization function at much lower cost
3Device complexity
If direct terminal-to-terminal synchronization is implemented, then device complexity and cost are reduced, but synchronization speed and efficiency need to be improved
Solution Approach 1:
The patent incorporates state information that indicates the current synchronization state of transmitting terminals. Receiving terminals can determine their receiving time information in advance based on this state information and time domain resources, allowing them to prepare for synchronization before actual signal exchange, thereby accelerating the synchronization process while maintaining simple device implementation
Solution Approach 2:
Terminals autonomously determine their own synchronization parameters (receiving time information) based on state information received from other terminals. This self-service capability eliminates the need for complex base station-controlled procedures, simultaneously reducing device complexity and improving synchronization speed through autonomous rapid adaptation
