Engineering Contradiction Analysis
1Measurement precision
If conventional synchronization monitoring is used, then the system maintains basic operation, but synchronization deviations are not detected early, leading to prolonged data transmission failures
Solution Approach 1:
The base station performs preliminary detection of synchronization deviations by monitoring uplink signals before complete desynchronization occurs. The synchronization determination unit continuously assesses whether the mobile station is in a synchronized or non-synchronized state, enabling early intervention and recovery before transmission failures are prolonged.
Solution Approach 2:
The system implements a feedback mechanism where the base station sends synchronization recovery requests to mobile stations that are determined to be in a non-synchronized state. The mobile stations respond with synchronization signals, creating a closed-loop feedback system that continuously monitors and corrects synchronization status, enabling early detection and recovery.
2Reliability
If continuous synchronization monitoring is implemented, then early detection capability is improved, but system complexity increases
Solution Approach 1:
The mobile station autonomously determines its own synchronization status by processing uplink signals and comparing them against expected parameters. This self-service approach allows each mobile station to independently monitor its synchronization state without requiring complex centralized monitoring infrastructure, thereby improving reliability while minimizing system complexity.
Solution Approach 2:
The base station's signal receiving unit serves multiple functions: it receives uplink data, control signals, and synchronization signals from mobile stations. This multi-functionality reduces the need for separate dedicated monitoring hardware, maintaining high synchronization monitoring capability while avoiding increased device complexity.
3Productivity
If early synchronization recovery is implemented, then communication efficiency is improved, but additional signaling overhead is introduced
Solution Approach 1:
The system applies synchronization recovery requests selectively only to mobile stations that are determined to be in a non-synchronized state, rather than broadcasting to all mobile stations continuously. This partial action approach maintains high communication efficiency by targeting only those units that need recovery, while minimizing unnecessary signaling overhead to synchronized mobile stations.
