Engineering Contradiction Analysis
1Reliability
If TCP/IP protocols are used for data transmission, then reliable delivery is achieved through re-transmission, but the protocol is too slow to adapt to rapidly changing data rates in 5G environments
Solution Approach 1:
The patent applies preliminary action by determining a designated data transmission rate in advance based on instantaneous data transmission capacity measurements. The network gateway pre-calculates appropriate transmission rates and communicates them to network entities before actual data transmission occurs, allowing devices to proactively adjust their transmission parameters rather than reactively responding to rate changes. This preliminary rate determination enables faster adaptation to 5G environment variations while maintaining reliable delivery through pre-configured transmission parameters.
2Productivity
If millimeter Wave spectrum is used for Fixed Wireless Access, then high data rates up to 10 Gbps are achieved, but high attenuation occurs even in fixed wireless access scenarios
Solution Approach 1:
The patent applies dynamics by continuously monitoring instantaneous data transmission capacity and dynamically adjusting the designated data transmission rate in response to changing channel conditions. The system transitions from static transmission rate configurations to dynamic rate adaptation, where the network gateway repeatedly measures capacity and updates transmission rates based on current attenuation levels. This dynamic approach allows the system to maintain high data rates when conditions permit while automatically reducing rates when attenuation increases, optimizing productivity despite mmWave challenges.
Solution Approach 2:
The patent implements feedback mechanisms where the network gateway continuously measures instantaneous data transmission capacity and uses this feedback to adjust designated transmission rates. The system establishes a closed-loop control where transmission performance measurements feed back into rate determination algorithms, enabling the network to adapt to attenuation variations in real-time. This feedback-driven approach allows the system to maintain optimal data rates despite the high attenuation characteristics of millimeter wave frequencies.
3Productivity
If the designated data transmission rate is set to the average data transmission capacity, then maximum throughput is achieved, but the rate is not always available due to fluctuations in the wireless link
Solution Approach 1:
The patent applies beforehand cushioning by determining a designated data transmission rate that is deliberately lower than the average data transmission capacity, creating a buffer or cushion against fluctuations. Instead of setting the rate at the maximum average capacity, the system selects a more conservative rate that is guaranteed to be available even when instantaneous capacity drops below the average. This cushioning approach trades some potential throughput for significantly improved reliability and availability of the transmission rate.
Solution Approach 2:
The patent applies parameter changes by adjusting the designated data transmission rate based on statistical analysis of instantaneous capacity measurements. The system changes the transmission rate parameter from a fixed average value to a dynamically determined value that accounts for capacity variations. By analyzing the distribution of instantaneous capacities and selecting an appropriate percentile or statistical threshold, the system optimizes the balance between throughput and availability, ensuring the designated rate is achievable with high probability while maintaining strong performance.
