Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual drive tests are performed to measure and optimize BCCH reception, then measurement accuracy is improved, but time consumption and labor costs increase
Solution Approach 1:
The terminal device automatically performs BCCH reception measurements and reports results to the base station without requiring external measurement equipment or manual drive tests. The network system self-optimizes by collecting measurement data from user terminals during normal operation, eliminating the need for dedicated drive test resources while maintaining measurement accuracy through multiple terminal reports.
2Manufacturing precision
If manual drive tests are performed to measure and optimize BCCH reception, then network optimization quality is improved, but labor costs increase
Solution Approach 1:
The system enables automatic network optimization by having terminal devices autonomously measure BCCH reception quality and report results to the base station. The base station collects these reports and automatically adjusts transmission parameters without requiring manual intervention from network engineers, thereby maintaining high optimization quality while dramatically reducing operational complexity and labor costs.
Solution Approach 2:
The invention implements a feedback mechanism where terminal devices continuously report BCCH reception status to the base station, which then adjusts transmission parameters based on this feedback. This closed-loop system maintains high network optimization quality by continuously adapting to changing channel conditions without requiring manual drive tests or complex operational procedures.
3Device complexity
If conventional transmission parameters are used for BCCH, then system simplicity is maintained, but reception performance deteriorates in poor channel conditions
Solution Approach 1:
The invention introduces dynamic adaptation of BCCH transmission parameters based on measured channel conditions. The base station adjusts transmission parameters such as power and modulation scheme according to the reception quality reported by terminal devices, enabling the system to maintain high reception reliability in varying channel conditions while preserving relative system simplicity through automated parameter adjustment rather than complex manual configuration.
