Engineering Contradiction Analysis
1Quantity of substance
If multiple synchronization signal blocks are arranged in a synchronization signal burst set, then the quantity of synchronization signals is increased, but the flexibility of utilization is reduced
Solution Approach 1:
The patent applies dynamics by making the synchronization signal block configuration adjustable and flexible. Different numbers of synchronization signal blocks (1, 2, 4, or 8 blocks) can be configured based on network conditions and requirements. The offset values for these blocks can be dynamically set to achieve consecutive or non-consecutive arrangements, allowing the system to adapt to various scenarios rather than being fixed in a rigid structure.
Solution Approach 2:
The patent utilizes parameter changes by modifying the offset parameters of synchronization signal blocks within the burst set. By changing offset values, the system can flexibly arrange blocks in consecutive or non-consecutive patterns. This parameter-based control enables the same basic structure to serve multiple purposes and adapt to different network conditions without requiring fundamental structural changes.
2Ease of operation
If synchronization signal blocks are arranged consecutively, then the arrangement is simplified, but the flexibility of configuration is reduced
Solution Approach 1:
The patent makes the arrangement dynamic by allowing the system to switch between consecutive and non-consecutive configurations based on needs. The offset parameters enable this dynamic adjustment, where consecutive arrangement provides simplicity for basic operations, while non-consecutive arrangement offers flexibility for advanced configurations and interference avoidance.
Solution Approach 2:
By changing the offset parameters, the system can transition between consecutive and non-consecutive arrangements. When offset values are set to create consecutive positions, the arrangement is simple and easy to manage. When offset values are adjusted to create gaps, the system gains flexibility for various configuration scenarios, thus resolving the contradiction through parameter control.
3Adaptability or versatility
If additional information is provided for terminal configuration, then the flexibility of utilization is improved, but the overhead is increased
Solution Approach 1:
The patent applies self-service by enabling terminals to autonomously determine the configuration of synchronization signal blocks without requiring additional explicit information from the network. Terminals can identify the number of blocks, their positions, and offset values through existing signaling mechanisms and predefined rules, reducing information overhead while maintaining flexibility in utilization.
Solution Approach 2:
The patent uses copying by leveraging existing information structures and signaling formats already present in the system. Rather than creating new information channels for block configuration, the system repurposes existing signaling resources to convey configuration details, thereby avoiding additional overhead while still providing necessary flexibility for terminal operation.

AI summary
An operation method of a communication node transmitting a synchronization signal in a communication network may comprise generating a synchronization signal block including the synchronization signal; configuring an offset for the synchronization signal block; generating a synchronization signal burst including a plurality of the synchronization signal blocks based on the offset; and transmitting the synchronization signal based on a synchronization signal burst set including the plurality of the synchronization signal blocks. Accordingly, a terminal can dynamically and effectively utilize the plurality of synchronization signal blocks without using additional information.
