Engineering Contradiction Analysis
1Reliability
If packet duplication is configured for a bearer using traditional cell configuration methods, then reliability of wireless communication is improved, but device complexity and configuration overhead increase
Solution Approach 1:
The base station is segmented into a central unit and a distributed unit, allowing the configuration of cell identities for packet duplication to be managed separately. The central unit handles high-level configuration while the distributed unit manages specific cell configurations, reducing overall system complexity and configuration overhead while maintaining reliability through distributed packet duplication across multiple cells
Solution Approach 2:
The base station pre-configures cell identities that can be used for packet duplication before actual data transmission begins. This preliminary configuration establishes a pool of available cell identities that can be quickly assigned for duplication purposes, eliminating the need for complex real-time configuration decisions and reducing configuration overhead during active communication
2Productivity
If multiple cells are configured for packet duplication, then productivity of data transmission is improved, but loss of information increases due to configuration inefficiencies
Solution Approach 1:
The base station implements feedback mechanisms where the central unit monitors the configuration status and performance of distributed cell configurations. This feedback loop ensures that configuration information is accurately maintained and updated across both central and distributed units, preventing information loss while enabling efficient multi-cell packet duplication for enhanced data transmission productivity
