Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If Cloud Radio Access Network (C-RAN) is implemented to increase network capacity, then network performance is improved, but deployment cost and complexity increase significantly
Solution Approach 1:
The patent segments the network into distributed base stations that operate semi-independently using millimeter wave links, rather than a centralized C-RAN architecture. This segmentation allows each base station to be deployed and managed independently, reducing overall deployment complexity while maintaining enhanced network capacity through coordinated multipoint operation.
Solution Approach 2:
The patent changes the operational parameters by introducing millimeter wave frequency links (24 GHz and above) for base station communication, enabling higher bandwidth and capacity without requiring the extensive fiber infrastructure of C-RAN. This parameter change achieves high network capacity with simpler deployment requirements.
2Ease of manufacture
If traditional network architecture is used to keep deployment simple, then ease of deployment is maintained, but network capacity is insufficient to handle high data traffic growth
Solution Approach 1:
The patent introduces millimeter wave wireless links as an intermediary medium between base stations, replacing the need for extensive fiber optic infrastructure required by C-RAN. This intermediary approach enables high-capacity coordinated multipoint operation while maintaining ease of deployment through wireless connectivity rather than physical fiber laying.
3Reliability
If coordinated multipoint operation is implemented to improve signal quality, then SINR is improved by 5db, but fronthaul traffic loading increases
Solution Approach 1:
The patent transitions to millimeter wave frequency dimension (24 GHz and above) for backhaul/fronthaul connections, providing vastly increased bandwidth capacity. This dimensional change in the electromagnetic spectrum allows coordinated multipoint operation and high-capacity fronthaul traffic to coexist without the bandwidth constraints of traditional lower frequency links.

AI summary
Methods, systems and devices for massive cooperative multipoint network operation are described. One example method for wireless communication includes transmitting, by a network node serving a plurality of mobile devices in a surrounding area, channel condition information and scheduling information for one or more of the plurality of mobile devices to a network-side server, receiving, by the network node from the network-side server, control information for scheduling transmissions to or from each of the one or more of the plurality of mobile devices, and controlling, by the network node and based on the control information, a communication to or from the one or more of the plurality of mobile devices at a future time or a different frequency band or a different spatial direction.
