Engineering Contradiction Analysis
1Device complexity
If multiple baseband circuits are provided with fewer antennas, then device complexity is reduced, but data transmission reliability deteriorates due to collisions
Solution Approach 1:
The radio frequency circuit provides collision information feedback to the baseband circuits about transmission collisions or receiving collisions. This feedback mechanism enables baseband circuits to detect collision situations and adjust their transmission timing accordingly, thereby maintaining data transmission reliability despite having fewer antennas than baseband circuits.
Solution Approach 2:
The system dynamically adjusts transmission timing based on collision information. Baseband circuits can change their transmission schedules in real-time according to the collision status reported by the radio frequency circuit, making the system adaptable to varying transmission conditions and preventing future collisions.
2Reliability
If timing synchronization is implemented for all baseband circuits, then data collision reliability is improved, but power consumption increases
Solution Approach 1:
Instead of implementing full timing synchronization for all baseband circuits, the system uses partial action by providing collision information only when collisions occur or are detected. This allows baseband circuits to operate independently most of the time, consuming less power, while still preventing collisions when necessary through targeted timing adjustments based on collision feedback.
