Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a higher error rate is used during initialisation phase, then communication speed and resource efficiency are improved, but transmission reliability deteriorates
Solution Approach 1:
The communication process is divided into two distinct phases: initialisation phase with higher error rate tolerance for fast configuration, and stable phase with target error rate for reliable communication. This segmentation allows each phase to be optimised independently for its specific requirements.
Solution Approach 2:
During the initialisation phase, the system performs preliminary measurements and determines communication configurations before entering the stable phase. This preliminary action enables the system to establish optimal parameters quickly without compromising final transmission reliability.
2Reliability
If a lower error rate (target error rate) is used during stable phase, then transmission reliability is improved, but communication efficiency and speed deteriorate
Solution Approach 1:
The system performs all necessary measurements and configuration determinations during the initialisation phase before transitioning to the stable phase. This preliminary action prevents the need for frequent adjustments during stable operation, thereby maintaining high communication efficiency while ensuring target error rate compliance.
Solution Approach 2:
Once the stable phase is entered, the system maintains continuous reliable communication using the pre-determined configurations. The measurements and adjustments are performed continuously in the background without interrupting the useful communication action, ensuring both reliability and efficiency.
3Adaptability or versatility
If different communication configurations are used for different phases, then adaptability to different requirements is improved, but system complexity increases
Solution Approach 1:
The system uses different communication configurations for initialisation and stable phases, with each configuration optimised for its specific requirements. The segmentation into distinct phases with distinct configurations enables high adaptability while managing complexity through clear separation of concerns.
Solution Approach 2:
The system dynamically transitions between different communication configurations based on the operational phase. The initialisation phase uses configurations optimised for rapid measurement and determination, while the stable phase uses configurations optimised for reliable communication, with automatic transition between them.

AI summary
A method of configuring transmissions in a mobile telecommunications network based on a target error rate for the transmissions, the transmissions being between a first mobile node of the mobile telecommunications network and a second mobile node of the mobile telecommunications network. The method comprises, in an initialisation phase, the first and second mobile nodes communicating (S801) in accordance with a first error rate and a first communication configuration, wherein the first error rate is greater than the target error rate; measuring (S802) an initial transmission quality associated with transmissions in the initialisation phase; based on the initial transmission quality associated with the first communication configuration, determining (S803) a second communication configuration corresponding to the target error rate; and in a stable phase, the first and second mobile nodes communicating (S804) in accordance with the target error rate and the second communication configuration.
