Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dual connectivity is enabled for all 5G-capable wireless devices, then data transmission capacity is improved, but resource consumption increases excessively for devices that do not qualify for MIMO transmissions
Solution Approach 1:
The patent applies local quality by differentiating resource allocation based on device capabilities. Devices are categorized into MIMO-eligible and non-MIMO-eligible groups, with different resource allocation strategies applied to each group. MIMO-eligible devices receive multi-stream transmissions utilizing spatial multiplexing, while non-MIMO-eligible devices receive single-stream transmissions, ensuring each device receives resources appropriate to its capabilities.
Solution Approach 2:
The patent implements dynamics by dynamically adjusting the number of MIMO streams and resource allocation based on real-time device pairing efficiency metrics. The system monitors pairing efficiency and adapts resource allocation accordingly, increasing MIMO stream utilization when pairing efficiency is high and reducing it when pairing efficiency is low, thereby optimizing resource consumption while maintaining data transmission capacity.
2Productivity
If MIMO transmissions are utilized for all eligible devices, then resource utilization efficiency is improved, but devices that do not meet pairing criteria cannot benefit from MIMO
Solution Approach 1:
The patent applies universality by creating a dual-mode transmission system that can serve both MIMO-eligible and non-MIMO-eligible devices through the same 5G air interface. The system provides multi-stream MIMO transmissions for eligible devices while simultaneously providing single-stream transmissions for non-eligible devices, making the network universally compatible with all 5G-capable devices regardless of their MIMO capabilities.
Solution Approach 2:
The patent differentiates transmission quality based on device capabilities. MIMO-eligible devices receive high-quality multi-stream transmissions with spatial multiplexing, while non-MIMO-eligible devices receive standard single-stream transmissions. This local quality approach ensures that each device receives the appropriate level of service based on its capabilities.
3Adaptability or versatility
If the number of wireless devices attaching to 5G air interface is increased, then network coverage and accessibility are improved, but pairing efficiency decreases when devices do not qualify for MIMO
Solution Approach 1:
The patent implements feedback by continuously monitoring pairing efficiency metrics and using this information to dynamically adjust resource allocation and transmission strategies. The system measures pairing efficiency based on the ratio of MIMO-eligible to total connected devices and adjusts MIMO stream utilization accordingly, creating a closed-loop control system that maintains optimal pairing efficiency while supporting device accessibility.
Solution Approach 2:
The system dynamically adjusts operational parameters based on real-time pairing efficiency conditions. When pairing efficiency is high (many MIMO-eligible devices), the system increases MIMO stream utilization. When pairing efficiency is low (few MIMO-eligible devices), the system reduces MIMO stream utilization to avoid wasting resources, thereby maintaining accessibility while optimizing efficiency.

AI summary
Limiting dual connectivity in a wireless sector served by at least two wireless air interfaces includes monitoring a pairing efficiency metric of wireless devices in the wireless sector. When the pairing efficiency metric rises above a threshold, a maximum number of wireless devices able to attach to one of the at least two wireless air interfaces is increased, and when the pairing efficiency metric falls below the threshold, the maximum number of wireless devices able to attach to one of the at least two wireless air interfaces is decreased. The wireless air interface for which dual connectivity is limited can be a 5G interface, and load is alleviated by limiting dual connectivity thereto.
