Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MDT mechanisms are used for 5G networks with higher frequencies and beam sweeping, then network coverage and capacity are improved, but interference identification accuracy deteriorates due to dynamic interference from mobile relays and other systems
Solution Approach 1:
The patent applies preliminary action by having the user equipment perform interference measurements and collect identity information about interfering entities before the interference significantly impacts network performance. The MDT mechanism is configured to measure interference levels and identify interfering cells or base stations in advance, allowing the network to take mitigating actions before severe degradation occurs. This is achieved through configured measurement objects that trigger measurements under specific conditions, enabling proactive rather than reactive interference management.
Solution Approach 2:
The patent uses an intermediary approach by introducing a dedicated MDT server or network entity that mediates between the user equipment and the network operator. This intermediary collects measurement data from multiple UEs, processes the interference information, and provides analysis results to the operator. The intermediary aggregates data from various sources including signal strength, quality indicators, and identity information, then presents processed insights that would be difficult to obtain directly from raw measurements alone.
2Measurement precision
If user equipment continuously monitors and transmits interference data, then interference analysis capability is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent applies partial action by configuring user equipment to perform interference measurements only under specific conditions rather than continuously. The MDT mechanism is triggered based on configured criteria such as signal quality thresholds, mobility events, or network-initiated commands. This selective measurement approach reduces the computational and energy burden on user equipment while still providing sufficient interference data for effective network optimization. The mechanism measures only what is necessary when needed, avoiding unnecessary continuous monitoring.
Solution Approach 2:
The patent implements multi-functionality by designing the MDT measurement mechanism to serve multiple purposes simultaneously. The same circuitry and measurement functions are used for both normal network operations and interference analysis. The user equipment leverages existing measurement capabilities for cell reselection, handover optimization, and quality assessment while also collecting interference data. This universal approach avoids dedicated hardware for interference measurement, reducing overall device complexity.
3Measurement precision
If user equipment stops signaling to enhance detection accuracy, then interference measurement precision is improved, but communication productivity decreases
Solution Approach 1:
The patent applies periodic action by implementing cyclic measurement and reporting intervals rather than continuous signal cessation. The network configures measurement periods during which the user equipment temporarily suspends normal communication signaling to perform interference measurements. These measurement periods are interspersed with normal communication periods, creating a periodic pattern of measurement and communication. This allows interference detection without complete communication shutdown, maintaining productivity while achieving measurement precision.
