Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently transmitting synchronization signals between terminals in diverse coverage scenarios, including in-coverage, partial coverage, and out-of-coverage scenarios, as well as across different cells, which hinders effective vehicle-to-everything (V2X) communication.
Innovation Solution
A method and apparatus for transmitting synchronization signals, where a first terminal receives configuration information from a base station, identifies transmission resources, and transmits synchronization signal blocks (SSBs) to a second terminal based on specific parameters, including offset, transmission interval, and number of transmissions, to ensure synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If synchronization signals are transmitted using existing methods, then basic synchronization can be achieved, but the system cannot efficiently handle diverse coverage scenarios (in-coverage, partial coverage, out-of-coverage) and inter-cell synchronization requirements
Solution Approach 1:
The patent implements dynamic transmission parameters including variable transmission intervals, offset values, and number of transmissions based on coverage scenario. The base station configures different SSB transmission patterns for in-coverage, partial coverage, and out-of-coverage scenarios, allowing the system to adapt dynamically to different operational conditions while maintaining reliable synchronization.
Solution Approach 2:
The patent changes key transmission parameters such as transmission interval, offset, and number of transmissions to optimize synchronization performance. By adjusting these parameters based on the specific coverage scenario and network conditions, the system achieves reliable synchronization across diverse environments without requiring separate dedicated signals for each scenario.
2Reliability
If multiple SSBs are transmitted with different parameters, then synchronization reliability improves, but the complexity of configuring and managing transmission parameters increases
Solution Approach 1:
The patent segments the SSB transmission configuration into distinct components: transmission interval, offset, and number of transmissions. Each parameter can be independently configured and optimized. The base station provides separate configuration information for each parameter, allowing flexible management of multiple SSB transmissions without overwhelming complexity.
Solution Approach 2:
The system incorporates feedback mechanisms where the base station monitors reception status of SSBs and adjusts transmission parameters accordingly. The terminal reports reception status, and the base station uses this feedback to optimize future transmissions, reducing the need for complex manual configuration and improving automatic adaptation to channel conditions.
