Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uplink transmission is performed in radio networks, then communication functionality is provided, but interference susceptibility increases leading to transmission failures
Solution Approach 1:
The patent implements a feedback mechanism where the terminal monitors uplink transmission failure rates and reports this information to the network node. The network node then uses this feedback to adaptively adjust the scheduling of uplink transmissions, thereby dynamically responding to interference conditions and improving transmission reliability.
Solution Approach 2:
The patent introduces dynamic scheduling adaptation based on monitored failure rates. Instead of static scheduling, the network node adjusts uplink transmission scheduling parameters dynamically according to the observed failure rate, allowing the system to adapt to changing interference conditions and improve reliability.
2Reliability
If monitoring of uplink transmission failure rate is implemented, then transmission reliability is improved through adaptive scheduling, but device complexity increases
Solution Approach 1:
The terminal autonomously monitors its own uplink transmission failure rate and generates reports without requiring complex external monitoring infrastructure. This self-service approach reduces overall system complexity while still enabling reliability improvements through adaptive scheduling.
Solution Approach 2:
The monitoring mechanism leverages existing terminal and network node functionalities, making them serve dual purposes: standard communication operations and failure rate monitoring. This multi-functionality reduces the need for separate dedicated monitoring components, thereby limiting the increase in device complexity.
3Reliability
If adaptive scheduling is implemented based on monitoring results, then interference is reduced and reliability improved, but loss of time occurs due to monitoring and reporting overhead
Solution Approach 1:
The patent implements partial monitoring by reporting failure rates based on selected uplink transmission types rather than monitoring all transmissions continuously. This selective approach reduces the time overhead for monitoring and reporting while still providing sufficient information for adaptive scheduling to improve reliability.
Solution Approach 2:
The patent changes the parameter being monitored from continuous transmission monitoring to periodic failure rate reporting. By transforming the monitoring approach from continuous observation to periodic measurement, the time overhead is significantly reduced while still enabling effective adaptive scheduling decisions.
