1Area of moving object
If retuning of RF chains is performed for wide bandwidth communications, then communication bandwidth is improved, but connection interruption and performance degradation occur
Solution Approach 1:
The system performs measurement and retuning operations in advance during designated measurement gaps before actual data transmission begins. This preliminary action ensures that RF chains are properly retuned to wide bandwidth frequencies before communication starts, preventing interruptions during active data transfer while maintaining connection continuity.
Solution Approach 2:
The system implements periodic measurement gaps at predetermined intervals during which RF chains can be retuned. These periodic interruptions are scheduled in advance and do not affect continuous data transmission, allowing the system to maintain wide bandwidth communication while periodically adjusting RF parameters without causing performance degradation.
2Measurement precision
If measurement gaps are introduced for RF chain retuning, then retuning accuracy is improved, but communication interruption time increases
Solution Approach 1:
The system performs measurements and retuning operations to a sufficient degree of accuracy during measurement gaps, rather than attempting continuous perfect tuning. This partial action approach achieves the necessary retuning precision for wide bandwidth communication while accepting brief, scheduled interruptions rather than attempting uninterrupted tuning that would be impossible to achieve.
